Where to get the obj files?

[lonnietc]

Hello,

I just came across this you Sparse Voxel Octree and wanted to replicate the output.

I downloaded the Windows_MSVC in the release section but it seems that it is missing the OBJ files for Crytek Sponza, San Miguel, and Living Room.

Where can I download these and others to test out? Thanks

Hello,

Thanks for the link and I was able to load one but when I changed the levels from 10 which worked nicely but coarse and blocky, and then reloaded the same level (sponza) and tried to use 12 or 15 levels then the application crashed.

Also, while I am still new to voxels systems, it seems that the OBJ files have both triangles which are used polygon engines and vertices which are used by voxel engines.

Does this mean that you are only using the vertices from the OBJ file? Thanks

Hi. For the second question, The OBJ file itself doesn't have any kind of "voxel vertices" in it. My application transform the vertices and polygon faces in an OBJ file to voxels with a voxelization algorithm (described in https://www.icare3d.org/research/OpenGLInsights-SparseVoxelization.pdf).

And for the first question, the capable max level is limited by your GPU's video memory and max render area since the voxelization algorithm runs on GPU (e.g. level 12 on sponza requires about 2GB of video memory)

I hope these explanations could help you.
