Massively Parallel Ray Tracing Algorithm Using GPU

Yutong Qin, Jianbiao Lin, Xiang Huang

摘要:

光线追踪是一种用于通过跟踪光穿过图像平面中的像素的路径并以大量计算成本模拟高质量全局光照的效果来生成图像的技术。但由于计算复杂度较高,不能满足实时绘制的要求。众核体系结构的出现,使得利用浮点运算的强大能力,大幅度缩短光线追踪算法的运行时间成为可能。本文提出了一种新的GPU实现和优化的光线追踪,以加速渲染过程。

英文摘要:

Ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of high-quality global illumination at a heavy computational cost. Because of the high computation complexity, it can't reach the requirement of real-time rendering. The emergence of many-core architectures, makes it possible to reduce significantly the running time of ray tracing algorithm by employing the powerful ability of floating point computation. In this paper, a new GPU implementation and optimization of the ray tracing to accelerate the rendering process is presented.
