Real-Time Rendering of Rut Based on Material Point Method
Visualization is the most intuitive expression to show scene inside or outside. Along with further study on three-dimensional terrain, rendering technology of terrain is not able to meet the high demands of picture clarity and fluency when render the scene. It is necessary to introduce numerical methods - material point method for accurate calculation of terrain deformation. Construct basic terrain by Geometry Clipmaps algorithm and then select NTVPM as dynamics model to interact with the terrain. The application of the material point method is for particle separation of terrain and calculation of force. Finally, the real-time rendering effect of rut is implemented by GPU. The experimental results show that the improved algorithm meets the truth and fluency of real-time terrain rendering. Observation from different viewpoints and comparative analysis before and after the application of the material point method on fps, CPU utilization.
