GPU Accelerated Voxelization Framework for 3D CAD models.

GPView voxelizes CAD models with a hybrid resolution. Supported CAD models are Wavefront (.obj) file and .off file formats. Output is in the form of binary .raw files with contiguous array.

Level1 resolution is a coarse level of voxelization and Level2 is a finer level of voxelization of particular Level1 voxels in a nested structure.
