BIM-Based 3D Reconstruction Technology

BIM-Based 3D Reconstruction Technology Optimization Model of BIM-based three-dimensional reconstruction technology and engineering model of visual perception Keywords: Three-dimensional reconstruction, visual perceptual model, engineering optimization, modeling, analysis. Abstract.Vision-based reconstruction is still there is a big limitation. Through its research-based approach introduces the primary visual three-dimensional reconstruction techniques, advantages and disadvantages of various methods were compared, it is desirable in this area can have a more comprehensive grasp, to further clarify the direction of future research. In order to improve the efficiency of the design and construction of bridge engineering, building information modeling (BIM) is introduced into the bridge project in the past. By analyzing the characteristics of bridge design and construction and the problems proposed bridge design and construction BIM-based optimization solutions, including preliminary design optimization, optimization of construction design, construction process optimization, optimization of the construction schedule and construction management optimization, combined with practical engineering project the applicability and effect analysis. Case application shows, BIM Bridge Project is applicable, can provide effective support for the bridge design and construction, thereby reducing rework and improve efficiency. The study may be large or complex bridge engineering BIM improve the efficiency and effectiveness of the design and construction of reference. Introduction The relevant information and data building information model is based on building projects as the basis for the model, building model were established by the real information of the digital information simulation building has, it has the visibility, coordination, simulated sex, optimality and showing of five characteristics. The BIM technology in the field of bridge engineering construction is currently in the early stages, preliminary exploration in the design, construction, and post-operation maintenance and repair of the entire life cycle of how to use BIM technology to improve design efficiency, improved design quality, strengthen the construction organization and post operations management, specific method and the application of BIM technology can bring benefits, hoping to BIM in bridge engineering to develop ideas. In recent years, domestic construction projects in the field of non-BIM is none other than the hottest technology in the construction industry has achieved good results after the application, the state began to vigorously promote the railway, highway, water conservancy and hydropower industry application of BIM technology in fields such as engineering, and bridge engineering in the construction field and a large proportion, especially high-speed railway, mountain railway, roads, bridges, often accounting for a larger significance in bridge engineering applications BIM technology on the entire major project, the paper will design, three stages of construction, operation and maintenance of the latter part of the project life cycle are the practical application of research needs and the effect of BIM technology. In recent years, should the needs of economic development, large, extra large bridge project more and more, such as China, Hangzhou Bay Bridge, the Hong Kong-Zhuhai-Macao Bridge, which bridge design and construction of a higher requirement. Bridge construction project not only involves complex geographical environment, and involves a number of complex projects, the most typical is the Steel Bridge. Currently, the design of large bridge projects usually rely on the traditional two-dimensional drawings and graphs to analyze the design by closing existing in conflict; construction planning is largely dependent on the experience of project managers to develop and implement, and is also a two-dimensional drawings to show. However, since the bridge project their own characteristics, its design complexity, component many rely solely on the traditional two-dimensional drawings difficult to detect in advance or found conflicts existing in the design; these design problems usually can be found in the construction phase, thus affecting the construction schedule and cost, will also affect construction safety. At the same time, in order to resolve the problem of engineering design and construction, we had to deploy more staff, which is also a significant increase in management costs. Therefore, to ensure the feasibility of the bridge may be constructed of engineering design and construction programs for efficient implementation of the bridge project is very important. Preliminary design stage is divided into two stages of design and post-design, including pre-design project approval, feasibility studies and scheme comparison and other parts, three-dimensional solid model of the bridge by using parametric modeling tools can be easily established according to the actual need to adjust the size, and the actual effect of the bridge into the real-time dynamic display, to achieve WYSIWYG, can intuitively design concept, design effects directly model the three-dimensional visualization of the project as a carrier to deliver policy-makers, which greatly facilitate the adjustment of the design, be revised in accordance with amendments and rendering, and cost control by adding information to keep abreast of changes after the investment increases and decreases, so that the bridge-bridge quickly determine preliminary program is very convenient and efficient. Figure 1 is a railway bridge stayed Bridge main bridge model, we need to establish a special bridge st ructure according to the characteristics of the family library for complex bridge structure using three-dimensional expression of BIM model than the traditional two-dimensional drawings clearer and easier to understand. The Proposed Methodology Three-dimensional modeling techniques.The use of modeling software for three-dimensional modeling is commonly used method, but modeling the need to spend a lot of manpower and material resources are often prohibitive, reconstruction effect is often unsatisfactory. Vision-based reconstruction technique to solve this problem and provides a new way of thinking. Three-dimensional vision-based three-dimensional reconstruction technology, which uses computer vision methods of three-dimensional model reconstruction of the object, is the use of a digital camera as the image sensor, the integrated use of image processing, visual computing technologies such as non-contact dimensional measurement, obtaining object using a computer program information. The advantage is that the shape of the object is not restricted to rebuild faster, can achieve automatic or semi-automatic modeling, three-dimensional reconstruction is an important direction of development, can be widely used, including autonomous mobile robot navigation systems, remote sensing and aerospace, industrial fields of automation systems, etc., the economic benefits generated by this technology is very impressive. As an important branch of computer vision technology, vision-based three-dimensional reconstruction of Marr visual theoretical framework is based on the formation of a variety of theoretical approaches. For example, according to the number of cameras can be divided into monocular vision method, binocular vision method, three monocular vision or monocular vision method; according to different principles, vision-based method can be divided into regions, feature-based visual method , model-based and rule-based visual methods; according to the obtained data the way, can be divided into active and passive visual method visual method. Figure.1 Three dimensional reconstruction technique According to research at home and abroad in recent years, were selected based on visual presentation of three-dimensional reconstruction of research and practical application of several methods and more comparative analysis, pointed out the main challenges for the future and the future direction of development. Depending on the number of cameras to use, this article will be divided into three-dimensional reconstruction method based on the visual method of monocular vision, binocular vision trinocular vision method and three methods were introduced, focusing on the monocular vision method. Monocular vision method.Monocular vision method is the use of a camera for three-dimensional reconstruction method. Images used can be a single point of view of single or multiple images can also be a multi-view multiple images. The former is mainly characterized by a two-dimensional image depth information deduced, these features include two-dimensional shading, texture, focus, contour, etc., it is also referred to as X shape recovery method. This simple device structure class methods, the use of single or small number of several images can be reconstructed three-dimensional object model; less than that normally required conditions more idealistic, practical application is not very satisfactory, the effects of reconstruction in general. The latter by matching different images of the same feature points matching using these coordinates in space constraint obtaining information in order to achieve a three-dimensional reconstruction. This method can be implemented in the reconstruction process of camera calibration, to meet the needs of large-scale reconstruction of three-dimensional scene, and in the case of resource-rich image reconstruction is better; the downside is that a greater amount of computing, a long time to rebuild. The following describes several major monocular vision method. Shading method.Shading method, that the brightness of the shape recovery method (SFS). This approach by analyzing image brightness information, using reflected light model, restore the normal to the surface of three-dimensional reconstruction information. Horn in 1970 first proposed the concept SFS methods, and gives a non-linear relationship between the two-dimensional image showing the brightness of each pixel in the corresponding three-dimensional point of law to the reflectance of light and the direction of Partial Differential Equations , the brightness of the equation. However, this method is a SFS under-constrained problem and needs to solve other constraints. Therefore, the traditional method of SFS also based on three assumptions. The main advantage of the brightness of the method is that it can recover from a single image in a more precise three-dimensional model can be applied in addition to mirror the object almost all types of objects. However, the brightness of the reconstruction of relying solely on mathematical calculations, results are poor, but because of the lighting conditions more stringent requirements, the need to know the precise position and orientation of the light source and other information, so that the brightness of the method is difficult to apply in the case of an outdoor scene lighting and other complex three-dimensional reconstruction on. Photometric stereo.Although the shading method to support the reconstruction of three-dimensional model from a single image, but less information is available in a single image, the actual reconstruction of the general effect. So Woodham of SFS method is proposed to improve the photometric stereo. Photometric stereo by a plurality of non-collinear light source to obtain multiple images of the object, and then a different image brightness simultaneous equations, solving the surface normal direction of the object, and ultimately restore the shape of the object. Technically, the use of two light sources can be obtained method object to the information, but the use of multiple sources of data redundancy can be resolved by the shadows and specular reflections caused by such factors can not solve the problem, better robustness, reconstruction effect It can be improved, so the current method basically using a plurality of (four to six) three-dimensional reconstruction of the light source. Photometric stereo advantages and brightness of the same law, the use of multiple images at the same time avoids the problems of ill shading method, and the use of multiple light sources also increased constraints, to improve the accuracy and robustness of the method; it the disadvantage is difficult to apply a mirror surface object and three-dimensional reconstruction of outdoor scenes and objects. Texture law.Humans can surface texture by projection on the retina perceive three-dimensional shape of the object, so the visual image information gradient texture can be used as information for Shape and depth cues. Based on this theory, the analysis can be repeated by surface texture unit image size, the shape, the recovery of the normal object, the depth information to obtain three-dimensional geometric model of the object, i.e., texture profile method for recovery. Texture is the basic theory of law: For a smooth surface and having a repeating texture units covering the object of which, when projected on the two-dimensional image, texture unit on which will be deformed, this deformation is divided into projection distortion (projective distortion ) and perspective shrinkage. Projection distortion so the farther away from the image plane texture unit looks smaller foreshortening distortion and image plane makes an angle greater texture unit looks shorter. Because these two variants can be measured from the image, so it can be analyzed after deformation texture units, reverse strike the surface normal and depth of information, three-dimensional reconstruction. Profile method. This method of contour images of objects through a plurality of angles to give a three-dimensional model of the object. Profile method can be divided based on voxel cone prime three methods based on visual and shell. Figure.2 Visual perception model Conclusion Reconstruction of 3D Vision technology is still in the exploratory stage, the practical application of the various methods is still some distance away from a variety of application needs to be urgently met. Therefore, in the future for a long period of time, we also need to do more intensive research in this field. This study shows that, BIM can provide effective support for the bridge design and construction. This study was expected to provide reference for increasing large, complex bridge design and construction efficiency and effectiveness, as well as assist in the promotion and application of BIM in the field of civil engineering. I believe that with the continuous promotion of theory and technology of BIM, BIM applications in civil engineering will become increasingly widespread, so as to improve their quality, efficiency and management level. Safety-critical structural bridge engineering, maintenance and repair of the late, operations management, file management can take advant age of powerful information technology BIM, visualization capabilities to achieve.

The Pleasure of Drugs Essay -- Pleasure Drug Abuse Essays

The Pleasure of Drugs The Oxford Dictionary defines pleasure. It is a feeling of satisfaction or joy. It is enjoyment. It is a source of pleasure or gratification. It is formally a persons will or desire. Finally they define it as sensual gratification. Now if we put these all together in one sentence, pleasure is something that brings an overall feeling of satisfaction and gratification while fulfilling desires. If that doesn’t sound good, what does? We have already determined that people naturally are drawn to altered states of consciousness. Its a fact that we are drawn to that which feels altered. It starts at a young age and hypothetically we realize the world of drugs and their ability to enhance normality by young adulthood. When we add in the pleasure principle to that already sought out feeling, you get something that feels so amazing, and is also potentially addictive. It is important to acknowledge the overpowering seductiveness and appeal of drugs. Because some drugs directly affect the way that the brain works and operates, the ecstasy that results can be overwhelming. This is exactly where society comes into play. If someone can only feel that sort of pleasure from the high of heroin or that calmness from a cigarette, why would they want to stop? What would their alternative be? It would be the pain of withdrawal and the numbness that they felt before they discovered the high. I can only liken my drug theory to a circle, because in reality there is no one who is really sober. There are things that make us all feel better. It can range from chocolate to caffeine to crack, but whether it be hard or soft, legal or illicit, a drug is something that makes us feel something other than â€Å"normal†. (Not that there is even a set normality.) The circle theory is that even if you are a heroin addict and get sober, the likeliness of you finding something else that makes you feel better than normal is high. It might not be heroin again, but chances are it will be something. It all comes back to the inherent human nature to find a plane of reality other than this one. We remember what feels good to us. It is something that our brain does for us. Because sex feels good, there is a natural desire to participate. We remember which foods we like best and how they make us feel when we eat them. It is a system i... ...ual. It has more to do with how our society dictates we should live. Everyone needs to be rich and own a BMW and marry a model and be happy all the time. For those who cannot live out that American Dream, there is an easy and more affordable dream: Drugs. We have to remember that they key to a healthy drug relationship is to use drugs in moderation, and not for the wrong reasons. It is important to keep in mind that drugs effect the body and the mind as well. Addiction is prevalent when the user can’t simple walk away from the drug and not miss it in some way or feel some type of withdrawal. We have to also understand that it is ok to feel the pleasure that drugs give to us. I will never condemn the use of drugs for recreational purposes, however we must each individually take responsibility for our own health and know when it is time to step away from a drug. Drug use does not always lead to addiction, but because pleasure is such a powerful drug within itself, it is easy to become dependent on something synthetic. Rather than relying on drugs for that pleasure high it is important to seek out other things besides drugs that induce the same types of pleasure.

Discuss the Advantages and Disadvantages of Owning a Car Essay

Everything has two sides to it, and there is no exception to owning a car. People can name just as many merits of owning a car as demerits of doing it. Apparently, convenience is one of the most important benefits that a car owner is looking for when spending huge sums of money for keeping one. Public transportation has developed rapidly in recent years in Vancouver. Yet, with the even faster expansion of Greater Vancouver Region, Vancouverites are expected to travel farther on a daily basis and there are always some places where you need to switch between trains, buses and seabus to arrive. Compared with driving, using public transport is time-consuming and tedious, esp. when you have luggage with you. Another benefit that driving brings you is to expand your life horizon to the extent that any other kind of transport can’t reach. Before coming to Canada, I lived about 200 kilometers from the world’s second largest desert: Taklimakan Desert. What is fascinating about the ‘sea of death’ is that a unique type of tree called diversi-formed leaves pillow have been flourishing in the heart of desert for thousands of years. The trees are said to be able to stand for 3 thousand years after dying, and lie for another 3 thousand years before rotting away. With a powerful Toyota 4700, my family used to visit the magnificent desert every year and are always stricken with breath-taking beauty of ‘Land of death and life’. In spite of these benefits that owning a car can bring us, the negative influence of driving to environment is also evident. Because cars are often single-occupied, driving means a huge more amount of gas emission than using public transport. In addition, keeping a car also requires constant extra expenses on fuel, parking and maintenance, let alone the considerable payment for car purchase and accidental damages. Things could be even worse when you fail to obey traffic rules and get penalties to pay for. Taking all these pros and cons into consideration, people often find it difficult to choose one over the other. Many people choose to drive for the convenience and freedom from harassments of hurrying to and waiting for public transport. Meanwhile, there are still more who enjoy a short time of relaxation on trains or buses instead of struggling to concentrate on driving after a tiring day.

When to Use a Singular or Plural Verb in Spanish

When to Use a Singular or Plural Verb in Spanish Spanish has several situations in which it may not be obvious whether a singular or plural verb should be used. These are some of the most common such cases. Collective Nouns Collective nouns - ostensibly singular nouns that refer to a group of individual entities - can be used with either a singular or plural verb for reasons that arent always clear. If the collective noun is immediately followed by a verb, a singular verb is used: La muchedumbre piensa que mis discursos no son suficientemente interesantes. (The crowd thinks my speeches arent sufficiently interesting.) But when the collective noun is followed by de, it can be used with either a singular or plural verb. Both of these sentences are acceptable, although some language purists may prefer one construction over another: La mitad de habitantes de nuestra ciudad tiene por lo menos un pariente con un problema de beber. La mitad de habitantes de nuestra ciudad tienen por lo menos un pariente con un problema de beber. (Half of residents of our city have at least one relative with a drinking problem.)   Ninguno By itself, ninguno (none) takes a singular verb: Ninguno funciona bien. (None function well.) Ninguno era fumador, pero cinco fueron hipertensos. (None were smokers, but five were hypertensive.) When followed by de and a plural noun, ninguno can take either a singular or a plural verb: Ninguno de nosotros son libres si uno de nosotros es encadenado. Ninguno de nosotros es libre si uno de nosotros es encadenado. (None of us are free if one of us is in chains.) Although some grammarians may prefer the singular form or make a distinction in the meanings of the two sentences, in practice there doesnt appear to be any appreciable difference (just as the translation of none of us is free in the translation might have been used with little if any difference in meaning). Nada and Nadie Nada and nadie, when used as subject pronouns, take singular verbs: Nadie puede alegrarse de la muerte de un ser humano. (Nobody can rejoice in the death of a human being.) Nada es lo que parece. (Nothing is what it seems.) Ni and Ni The correlative conjunctions ni ... ni (neither ... nor) is used with a plural verb even if both of the subjects are singular. This is different from the corresponding English usage. Ni tà º ni yo fuimos el primero. (Neither you nor I was the first.) Ni el oso ni ningà ºn otro animal podà ­an dormir. (Neither the bear nor any other animal could sleep.) Ni à ©l ni ella estaban en casa ayer. (Neither he nor she was at home yesterday.) Singular Nouns Joined by O  (Or) When two singular nouns are joined by O, you usually can use a singular or plural verb. Thus both of these sentences are grammatically acceptable: Si una ciudad tiene un là ­der, à ©l o ella son conocidos como ejecutivo municipal. Si una cidudad tiene un là ­der, à ©l o ella es conocido como alcalde. (If a city has a leader, he or she is known as the mayor.) However, the singular verb is required if by or you mean only one possibility and not both: Pablo o Miguel ser el ganador. (Pablo or Miguel will be the winner.)

Learning and Cognition

Learning and Cognition Introduction According to Kimble (1961), learning is taken as the process that brings in a relatively permanent alteration in behavior or potentiality in behavior as a result of reinforcement. For leaning to take place there must be a permanent change in the behavior. Therefore learning omits those behavior changes that are not permanent such as sleeping, eating and so on. In addition the term learning also do not consider the permanent changes that result due to maturation as learning process.Advertising We will write a custom essay sample on Learning and Cognition specifically for you for only $16.05 $11/page Learn More Learning and Cognition Whenever learning occurs, it is manifested as a change in behavior. The change though does not result immediately after learning, but occurs after some time span. Since learning cannot be studied directly, learning of behavior change is an important aspect because gives an inference to the process that preside behavio r change and hence making the study of learning possible. Except for B.F. Skinner who considers reinforcement and punishment as the most important aspects of learning behavior, majority of the learning theorist consider that learning compose of a superseding variable between experience and behavior (Olson Hergenhahn, 2009). This helps to differentiate performance and learning where performance exhibit the real learning as a behavior, although learning is regarded to take place before the exhibition of the learned behavior through performance. Thus it should be taken to represent potential for future behavior. Thus in summary, learning can be taken to represent behavior in potential that signify a superseding variable between experience and behavior; that ultimately gets expressed through the tool of performance. Conditioning is one process through which learning takes place. This type of learning was initially formulated by Pavlov and later augmented by Skinner. Conditioning can fu rther be split into two groups. These are classical conditioning and Instrumental conditioning. In the former conditioning, learning occurs when animals master how to associate neutral stimulus with natural stimulus they are familiar with. For instance classical conditioning results when a dog salivates when a man with a lab coat passes. This can happen only if the man that feeds the dog wears a lab coat every time he does it. Therefore the dog learns to associate the lab coat with food. Thus every time it sees a lab coat it associates it with food. On the other hand, the latter conditioning is also known as operant conditioning and it occurs when a behavior that already exists is reinforced in order to increases its chances of reoccurrences (Olson Hergenhahn 2009). Similarly it occurs when an animal masters to act in a certain manner in order to receive an intrinsically rewarding stimulus. This can be inferred by jumping of a trained dolphin from a pool of water so that to get a f ish.Advertising Looking for essay on psychology? Let's see if we can help you!

These forms of learning are very important in the day to day lives since Classical conditioning is used to differentiate between those objects that are essential for survival and those that are not, while on the other hand, operant conditioning is used for avoidance of unwanted objects. Almost every theory of learning includes cognitive association into the general stimulus-response relationship advocated by operant and classical conditioning. The said cognitive association can occur between an occurrence of two stimuli (S-O), depiction of a stimulus and response (S-R) or finally a representation of a response and an outcome (R-O). The most important factor in all these associations is that anticipation of the results acts as the mediator between learning and performance. T herefore the S-R association can result from preconditioning events (Kimble, 1961). For instance introducing of a pairing related stimuli and do away with any reinforcement which will result into the expectation that future representation of one of the stimulus will lead to the occurrence of the other one. On the other hand, reducing the frequency of representation of a set of stimuli will reduce the future expectancy of the representation of the desired stimuli or response. For example when a dog is conditioned that every time it sees a man with a lab coat it gets its food will salivate every moment it sees any man wearing a lab coat. Therefore there is a general expectancy that when the dog sees a man with a lab coat it will definitely salivate since it associates the lab coat with the stimulus it is familiar with food. If this procedure is altered and the dog does not get its food every time it sees a man with a lab coat, its expectation that it will salivate every time it sees a man with a lab coat decreases. Conclusion Behavior change can be regarded as the ultimate result of learning that is represented through the instrument of performance. Classical conditioning and instrumental conditioning are considered as the two forms of learning through which other form of learning can be linked to. It is from this learning paradigm that forms the basis of cognitive association which tries to explain the expectancy of future happenings as a mediating variable that helps to build a framework to enable comprehend cognitive processes so that to assist in.

Project Management Assignment Coursework Example | Topics and Well Written Essays - 500 words

Project Management Assignment - Coursework Example 60 days are required to finish the project. Theoretical smallest maximum number : 632/60 = 10.53 ~ 11. The critical path is B – D – H – K – L. This number is not practical without the interference of the critical path as all activities on the critical path apart from L on a slight note, are dependent on other activities and some overlap with other activities that demand human resource too. An imbalance would alter the duration of some dependencies thus directly affecting the critical path. However, with the more human resource, the implementation would have been viable and would have been implemented to in fact reduce the duration with a condition that the activities were done only in succession. The practical maximum number could thus be 10 while the practical minimum would be 2 as provided by the initial schedule. The critical path is through B, D, H, K, and L. this totals to 38 days. To maintain a maximum number of 14 humans at a time without interfering with the critical path duration in the schedule, we have to increase the duration of activity B to 10 days and reduce the human resource to 3. We then increase the duration of C to 21 days and reduce humans in the same activity to 2 humans. Finally, we reduce the duration of activity K by increasing human resource by 2 to 8. These changes ensure that at any particular time, including overlapping dependencies, the number of human resources is maintained by 14 humans. The schedule is redrafted in the above-drawn table.

Assignment Research Paper Example | Topics and Well Written Essays - 1000 words

Assignment - Research Paper Example The interface is easy to understand and use. There is a provision for requesting orders and other queries. The website shows a provision with Amazon.com where the user can place their requests. The overall visual appeal of the website is captivating enough to reaction the interest of the user (Harry Potter Wizards Collection). Answer 2 The Harry Potter Wizard’s collection presents a vast array of the products and merchandise that was used in their marketing. The first site in the wand gestures section contains information about the collection offered in the website. It offers Harry Potter and the deathly hallows cd for both part1 and part2 versions in 2D and 3D versions. It also contains map of Hogwarts, concept art prints and catalogs of props as well as posters that were prepared by the graphic designers of the film. The second site labels collection contains a book of 32 pages that provides the prop labels such as the ones used in the magic potions, vials for memory, Honey dukes as well as Weasleys' Wizard Wheezes. There are also videos showing the complete collection of Harry Potter goodies and merchandise. From the visual content of the site, it has been built keeping in mind the wizard and magical content of the film. There is a brilliant usage of red, black and golden color in the site. The wand has been used for navigation purpose that makes it more interesting and produces a magical feel in the users. Apart from the cd, videos and other merchandise featured in The Harry Potter Wizard’s collection, the company Warner’s Brothers can use Harry Potter products like bags, coffee mugs featuring the different characters. They can also sell garments like t-shirts, sweatshirts for both boys and girls similar to the ones that were worn by the three main characters in the films. Thirdly, the company can organize trips for the masses in their make shift locations of the film. Answer 3(a) After examining the two sites for Harry Potter and batme n it was found that both the movies offer the same type of merchandise to the consumers. Items Available for Harry Potter Items Available for Batman DVD for Harry Potter series like Harry Potter wizard collection. Sound tracks like the Harry Potter and the Deathly Hallows Part Two: Original Motion Picture Soundtrack CD, iphone cases featuring the film logos, bags and accessories such as earrings, necklace, pins etc. there were clothing for both kids and adults. Gift items were also available. DVD for Batman series like the animated series- tales of the dark knight. Digital video games were present such as the Arkham city. Plush toys featuring Batman costumes were available. Accessories in the form of backpacks, hats, jewelry, clothing like shirts for kids and adults, robes, jackets and sweatshirts were available. Most of the products available for the two movies are same in nature. It can be explained using porter’s differentiation strategy of the generic strategies model. Th e market for animated films and 2D/3D genre is very competitive and saturated. Also, Warner Brothers had the right elements to satisfy the needs of the movie fans. This helped them in creating a different brand identity for each films though the underlying physical commodity was the same such as the coffee mugs (Botten 276). Apart from these, movies such as the Lord of the Rings, Scooby Doo etc are featured in the Warner website. As Warner
