Design And Implementation Of Zhu Cheng Dinosaur Park Virtual Reality System

With the rapid development of Computer technology, Computer Graphical(CG) element has become more and more influence in each aspect of our lives. Theses aspects include our common special effects in movies, TV ads, games, and virtual reality. Virtual reality technology, multimedia technology is widely applied after the rise of the new computer technology, it can be used to include virtual scene, virtual product, virtual planning, real estate, museums and even military simulation domain.Zhu Cheng dinosaur park VR system is the theme systerm of dinosaurs, this VR system mainly describes the form in different periods, the movement, the dinosaurs and dinosaurs living environment calls, through utilizing the virtual camera displacement to the more direct users can understand the knowledge about dinosaurs. Meanwhile, this system also support the user through virtual camera displacement and rotated operation to the interaction between with dinosaurs. In a scene model for system modeling effects, this paper mainly use paint brush the repository rich plant brush, easy to realize many glaring modeling effect. For interface design is concerned, the main research how to use concise vivid cut-scenes to complete our time axis to change for the control, thus completing our time, space for the transition. Based on this system characteristic, the actual production of departure from the system, the main research work and achievement from the following aspects:1. The detailed analysis of system requirements and core technology is proposed, based on the whole system framework design scheme.2. Different species of trees by generalizing the characteristic of structure, the complete system of basic trees, combined with model framework modeling Effects tools modeling features Paint to model, at the same time use path curve drawing complete dynamic generation of the model.3. Through comparing the different kinds of grassland, the structural characteristics of complete system basic grass plants, and modeling study particle system to generate, combined with Sprite display attributes complete grass plants model.4. Through inductive different kinds dinosaur characteristics, complete system model dinosaur modeling and analysis model dinosaur polygon features, complete system model dinosaur foundation model classification and basic production. Finish the polygon method and combining with the particle system instantiation to for dinosaur group modeling. Combined with practical fractal structure characteristics and dinosaur garden various special landform, complete dinosaur park standard terrain modeling. Build a dinosaur Skeleton, combined with the basic dynamic repository for the model tools for the dynamic production including running, worrying, chase, roar, etc.5. Combined with this system development direction and system interface design, complete system theme of displacement based on virtual camera with model dinosaur distance generation interaction, including running, dinosaur 5.3s roar bite marks, chase, events such as the feedback. At the same time use data to the helmet for system, combining with calm type using virtual data glove for some touching of firing incident.6. Through the system tests and analyse the data. Mainly to the system shows the real degree, interactive performance, data delay, data storage efficiency and related data test, test results demonstrate the design idea, can satisfy the project needs.
