Can you use cuFFT with the VolumeGVDB class?

I’m looking at the documentation for cuFFT and the input datatypes do not include VolumeGVDB. Is there a way to perform a 3D FFT on VolumeGVDB data? Or do I need to perform some sort of data conversion for cuFFT.

Thanks

What is VolumeGVDB? What is the data layout?

Thanks for sending the cuFFT datatype. I’ll provide a bit of context. I’m trying to convert a 3D model (polygonal mesh) to a GVDB Data Structure. In order to perform the conversion, I use the SolidVoxelize function. I believe this will result in the voxels having a channel that I can read their value which may be a float or an int. I’m not even sure there will be a value at the voxel because just their presence in the datastructure should imply a value.

So given this GVDB structure which corresponds to a voxelized part, how do I perform a 3D FFT(cuFFT) on the GVDB datastructure. Do I have to write my own function to map a GVDB DataStruct to cuFFTReal?

Can only post one link at a time so here is a link to SolidVoxelize
