WebLike all images in this chapter, it was rendered with a GPU-based global illumination algorithm that uses rasterization hardware for efficient ray casting. Figure 38-1 An Image Rendered with Global Illumination Accelerated by the GPU. Techniques for including these effects usually require ray tracing for high-quality results. WebThe main idea is: each stair is a sequence of lines with similar domain of definition, and the staircase is a sequence of such elements. To avoid unnecessary computations, an octree is used to down-sample the environment point-cloud data. The resulting centroids are stored in n arrays, each containing points with equal height.
