With the rapid development of computer technology, CG (Computer Graphical) elements more and more impact in all aspects of people's lives. Including common special effects in movies, TV commercials, games, and virtual reality. Virtual reality technology, the rise of multimedia technology is widely used new computer technology, usually used to include the virtual scene, virtual products, virtual planning, real estate, museums and even the field of military simulation. Zhucheng Dinosaur Park VR system is a dinosaur-theme of the main elements of the VR system, the system describes the morphology of the different periods of the dinosaurs, movements, sounds, and dinosaur living environment, enabling users to take advantage of the displacement of the virtual camera to more direct understanding of the knowledge about dinosaurs. At the same time, the system also supports the user by the displacement of the virtual camera rotation operation with the interaction between the dinosaurs. System scene modeling using Paint Effects brushes library rich in plant brushes easily dazzling modeling effect. In terms of interface design, mainly to study how the use of simple and vivid cutscenes to complete the timeline change control, thus completing the transition time, space. For the characteristics of the system, starting from the actual production of the system, the main research work and achievements include the following sections: 1. Based on detailed analysis of the system requirements and core technology, the proposed system overall framework design. Summarized the structural characteristics of the different types of trees, complete system basic model framework for modeling trees with Paint Effects tool modeling features of the model drawn, while taking advantage of the completion of the path curve dynamically generated model. By comparing the structural characteristics of the different types of grass plants to complete the modeling of the system basic grass plants, and at the same time of particles generated by the system, combined with the completion of the Sprite Display Properties grass plants modeling. 4. Summarized the characteristics of different types of dinosaurs, complete systems dinosaur model modeling, analysis dinosaur model polygon features, the completion of the basic model classification and basic production systems dinosaur model. Complete the polygon modeling methods combined with particle system instance modeling dinosaur groups. Combined with the actual the dinosaur garden-shaped structure characteristics, and a variety of special topography, the standard terrain modeling complete Dinosaur Park. Establish the the dinosaurs basic dynamic library to combine the Skeleton tools to model the dynamic production including running, biting, chasing, roaring. With the direction of the development of the system and the system theme complete system interface design, interaction based on the distance of the virtual camera displacement dinosaur model, the firing of dinosaurs, including running, biting, chasing, roaring events such feedback. While taking advantage of the the data helmet, combined with the use of data gloves to touch-type firing system quiet virtual event. System test and data analysis. The major test of fidelity, interactive performance, data latency, data storage efficiency data, test results verify the design concept, able to meet the needs of the project.
