The personal website of Hector Piteau.en https://hepiteau.com/projects/sparse-voxels/https://github.com/hectorpiteau/sparse-voxelsA sparse voxel octree toolkit for representing and rendering 3D data. It combines a C++20/CUDA core with Python bindings for spatial queries, ray casting, and volume rendering. PyTorch integration makes density and color fields differentiable, connecting my work in 3D graphics with learning-based reconstruction.
