Research And Implement Of Particle Technology In Scene Of Crane Simulator

The environment of tower crane has a wide range of special features, that means the performance varied, and the main feature is the unfixed shape, irregular movement, as same as difficult to use conventional methods to simulate modeling and rendering, In the meantime, the model is often difficult to take into account the reality, and hard to turn into real-time requirements. Irregular particle system is used for modeling fuzzy objects and images generated by a method that uses a completely different from the previous modeling, rendering a systematic approach to construct and draw the scene, which can form a landscape form and features of the overall Dynamics. In this thesis, crane driving simulator is a scene of realistic virtual reality based on the design and implementation of particle effects.This research project topics come from The State Administration of Quality Supervision Loop Simulation Based on Tower Crane Simulation Training System (item number:2009QK0293) and The Safe Operation of Tower Cranes Cluster Intelligent Control System (item number:2009QK0294). The design firstly describes Virtual reality system and the basic concepts of particle effects to generate rules and process. Through the existing particle system visual effects of various research and analysis, it will be pointed out that there are many inadequacies in the existing particle effects, so the program should be improved. Meanwhile, according to the existing collision detection techniques, the particle system approach would be analyzed in order to making the scene more realistic.Adding large particle effects to the system as application can effectively enhance the authenticity of the scene to make the system more powerful and better user immersion. This realization of a variety of particle effects, such as rain and snow effects, fog effects, sparks construction site, surface dust, effective scene in the snow, and so on. The collision detection of particle technology is firstly used in calculating the motion of particles, so that snow particles cannot pass through other objects in order to achieve a more realistic scenario. In my design, there are three kinds of special effects scenes, a motion control and two aspects of the study, based on the characteristics of particles in the scene. The main technology is modeling methods based on texture, combining the real-time rendering, and the establishment of a variety of realistic special effects scenes, which not only increase the scene's Immersion but also improve production efficiency. To make a more realistic particle effects scenes, we use the collision detection technique to control the movement of snow particles. Then the results and analysis of the collision between particles and other models are given. Finally all functions have come true based on the.net development platform. We achieve a tower crane driving simulator scene Roaming. The last work is a summary of this article.
