AI-powered developer The main problem (at least for me) was that the GVDB needs the graph library to work and this library is not supported for SM=20 and sm=21 (I know that they are going to be deprecated) devices therefore neither the GVDB library either, is my believed that this should be in the library documentation when I try to installed I did look if it was possible to install on a 21 I'm trying to use GLFW in place of NVPWindow because i want to run a voxelization in background without a window.

Write better Yes, the only small issue I had with gvdb.

Yep, @icoderaven's answer is correct - textures are interpolated as if each voxel/texel's value is specified at the center of the voxel/texel, so when using a texture with linear interpolation you have to add an offset of half a voxel to avoid blending with other voxels. main Sparse volume compute and rendering on NVIDIA GPUs - NVIDIA/gvdb-voxels Sparse volume compute and rendering on NVIDIA GPUs - NVIDIA/gvdb-voxels Sparse volume compute and rendering on NVIDIA GPUs - NVIDIA/gvdb-voxels The missing package manager for OS X.
