Voxelith
Voxelith transforms smooth 3D models into beautifully structured voxel representations. At its core, a recursive octree (Divide and Conquer) algorithm decomposes complex meshes into hierarchical cubic units with surgical precision. Every triangle tested. Every empty region pruned. The result is a real-time interactive viewer with a custom software rendering pipeline, depth-sorted face drawing, and cinematic auto-orbit. No GPU abstraction layers, just pure math.
