"Web3. Boundary Representations (B-Rep) A boundary representation for a solid stores the topology as well as the geometry of the solid. Geometry models position, size, and orientation; topology models adjacency and connectivity. Constructive solid geometry models the geometry of a solid, but the topology of a solid is not present in a CSG tree. " - Ray casting for modeling solids pdf

WebAbstract. Ray tracing, ray casting, and other forms of point sampling are important techniques in computer graphics, but their usefulness has been undermined by aliasing artifacts. In this paper it is shown that these artifacts are not an inherent part of point sampling, but a consequence of using regularly spaced samples. Web2.2 Ray Casting Algorithm The CUDA algorithm for ray-casting is given in Algo-rithm 1. In ray-casting, all rays of a tile operate in parallel. Each ray intersects with all triangles of the …
