基於圖形處理器的即時頭髮渲染與模擬

Abstract

在這篇論文中，我們展示了一個基於圖形處理器的即時頭髮渲染與模擬實做。一直以來，有許多研究利用流體力學的方法來處理頭髮模擬的問題。其中一個可行的方法是用FLIP (Fluid-Implicit Particle)來維持頭髮所佔有的體積以及處理頭髮彼此之間的碰撞。我們呈現一個在CUDA計算能力1.1圖形處理器上模擬演算法的實做。基於OpenGL 4.0繪圖流程，我們的渲染程式可在繪圖硬體上動態地調整頭髮模型的細節來增進效能。

In this thesis, we demonstrate an implementation of real-time hair rendering and simulation program on graphics hardware. There have been many researches which applied fluid dynamics to deal with some problems in hair simulation. One of the workable methods is applying the FLIP (Fluid-Implicit Particle) method to maintain the hair volume and to handle the hair-hair collisions. We present an implantation of the simulation algorithm on graphics card with CUDA compute capability 1.1. Based on OpenGL 4.0 pipeline, our rendering program is able to dynamically adjust the detail of hair model on graphics hardware to achieve better performance.
