Abstract: Aiming at the problem that the current HI-Z (Hierarchical Z-Buffer) occlusion culling algorithm has culling errors and occupies too much CPU computing power, this paper proposes a GPU-based ...

Stage 4: clipping & scan conversion using Z-buffer algorithm Your program will output five files: stage1.txt, stage2.txt, stage3.txt and z-buffer.txt, out.bmp. The first three files will contain the ...

Ray-tracing is one of the most researched areas in 3D photo-realistic image synthesis. We propose the T-BUFFER algorithm, which is a modification to the conventional ray-tracing algorithm and compares ...
