WebVoxel Vendredi is a discussion thread starting every Friday - 'vendredi' in French - and running over the weekend. The thread is automatically posted by the mods every Friday at 00:00 GMT. Previous Voxel Vendredis: see search result , or on the new reddit the Voxel Vendredi collections: 1 to 99 and current . WebAn algorithm is described that speeds up ray-tracing techniques by reducing the number of time-consuming object-ray intersection calculations that have to be made. The algorithm is based on subdividing space into an octree, associating a given voxel with only those objects whose surfaces pass through the volume of the voxel. It includes a technique for …

WebMay 8, 2014 · Voxel-based ray-tracing methods attract more and more attentions recently, because of geometry-independent scene description and the evolving of fast voxelization methods. Some scene voxelization and ray-voxel intersection techniques have been proposed for rendering global illumination interactively [21–26].
WebMajority of the perception methods in robotics require depth information provided by RGB-D cameras. However, standard 3D sensors fail to capture depth of transparent objects due to refraction and absorption of light. I… WebA ray-driven backprojector is based on ray-tracing, which computes the length of the intersection between the ray paths and each voxel to be reconstructed. To reduce the computational burden caused by these exhaustive intersection tests, we propose a fully graphics processing unit (GPU)-based ray-dr …
