Glsl octree
WebAn octree is a tree-based data structure for managing sparse 3-D data. Each internal node has exactly eight children. In this tutorial we will learn how to use the octree for spatial partitioning and neighbor search within pointcloud data. Particularly, we explain how to perform a “Neighbors within Voxel Search”, the “K Nearest Neighbor ...

I use an octree to spilt the data in chunks of manageable 3D textures, and then use a back to front rendenring of slices of the octree with proper blending to obtain a fake raycasting solution (nothing new here). My problem is that there are visible …

Here the octree is built on the GPU using a 3D volume texture for data storage (leaf nodes) and a brick pool for allocating internal nodes, built from the bottom up then mip-map'ed for ray casting. If you are willing to bend a bit, there is a big project on sparse voxel octree's using CUDA, which would provide valuable insight into sparse ...
