| 摘 要： | 光线跟踪算法是真实感图形学中体绘制的主要算法之一,本文分析了基于GPU的光线跟踪技术的实现原理,设计了基于流的GPU光线跟踪体绘制方法。根据设计的三个实验场景所包含的三角形面片数,在2种不同分辨率下,分别实现GPU和CPU的光线跟踪绘制。通过实验结果比较、分析,发现随着场景复杂度的增加,基于GPU加速的光线跟踪算法将明显优于CPU上的算法。

| Abstract: | Ray Tracing Algorithm is a main algorithm for volume-rendering in photorealistic rendering. In the paper,the prin- ciple of the ray tracing based on GPU are analyzed and designs the algorithm based on stream for GPU. according to the count of the triangle surfaces in the three experiment scenes,realized the algorithm on GPU and CPU in two resolutions. With the re- sult,It was found that the algorithm on GPU is better than on CPU,especially obvious in the more complicated scene. |
