一种基于空间索引技术的全局光照快速绘制算法

在研究分析各种光照模型算法的基础上,提出一个基于对场景空间规则划分索引及建立光粒子空间分布,并以此进行全局光照计算的模型,其中包括提出一种从光源自适应地发射光粒子的模式和基于空间分割索引传播存储光粒子的技术,以及从视点出发的空间索引定位光粒子的收集显示方案.在算法实现的过程中,由于采用了场景空间规则划分的有序索引、对光...

A FAST GLOBAL ILLUMINATION RENDERING ALGORITHM BASED ON SPACE INDEXING TECHNIQUE

In this paper,we present a model of global illumination calculation which is conducted on the basis of partitioning and indexing the scene space rules and building the spatial distribution of light particles,according to the studies and analyses on various illumination model algorithms.The model includes a pattern to emit light particles adaptively from light sources and the technique of spreading and storing the light particles based on space segmentation index,as well as the collection and display scheme ...
