-This project is a voxelizer implementation in Rust using the Digital Differential Analyzer (DDA) algorithm. The DDA algorithm was chosen for its simplicity and efficiency in voxelizing 3D models.
+A 3D mesh voxelizer implemented in Rust using the DDA (Digital Differential Analyzer) algorithm. The DDA method is simple and fast when you only want to voxelize the surfaces of meshes.
