[Abstract]:With the rapid development of computer technology, CG (Computer Graphical) elements affect people's lives more and more. These include common movie effects, TV ads, games, and virtual reality. Virtual reality (VR) is a new computer technology developed after the wide application of multimedia technology. It can be used in the fields of virtual scene, virtual product, virtual planning, real estate, museum and even military simulation. The VR system in Zhucheng Dinosaur Garden is a thematic VR system with dinosaurs as its main element. The system describes the morphology, movements, sounds and living environment of dinosaurs in different periods. By using the displacement of virtual cameras, users can learn more directly about dinosaurs. At the same time, the system also supports users to interact with dinosaurs through virtual camera displacement rotation and other operations. For system scene modeling, this paper mainly uses the abundant plant brushes in the Paint Effects brush library to easily realize a lot of dazzling modeling effects. For interface design, the main research is how to control the time axis change by using vivid and concise animation to complete the transition of time and space. According to the characteristics of the system, the main research work and results are as follows: 1. Based on the detailed analysis of the system requirements and core technologies, the design scheme of the overall framework of the system is proposed. 2. By summarizing the structural characteristics of different species of trees, the model framework modeling of the basic trees of the system is completed, and the modeling characteristics of Paint Effects tools are combined to draw the model. At the same time, the dynamic generation of the model is accomplished by using the path curve. 3. By comparing the structural characteristics of different species of grassland plants, the model modeling of basic grassland plants in the system is completed. At the same time, the generation of particle system is studied, and the model modeling of grassland plants is completed with Sprite display attributes. 4. By summarizing the characteristics of different kinds of dinosaurs, the modeling of the system dinosaur model is completed, the polygon characteristics of the dinosaur model is analyzed, and the basic model classification and basic making of the system dinosaur model are completed. The polygon modeling method combined with particle system instantiation is used to model the dinosaur population. The standard terrain modeling of the dinosaur garden is completed by combining the topographic structure characteristics of the actual dinosaur garden and various special landforms. The basic dynamic library of dinosaurs was established, and the model was made dynamically with Skeleton tools, including running, biting, chasing, roaring and so on. 5. According to the displacement of the virtual camera and the distance between the dinosaur model and the system interface design, the system interface design is completed, and the dinosaurs' running, biting, chasing, roaring and other incident feedback are generated according to the displacement of the virtual camera and the distance of the dinosaur model. At the same time, the data helmet is used to simulate the system, and the data glove is used for the point-touch event. 6. Test the system and analyze the data. The system display reality, interactivity, data delay, data storage efficiency and other related data testing, the test results verify the design concept, can meet the needs of the project.
