Images bigger than 2^32 voxels can not be recosntructed on GPU. #404

Closed AnderBiguri closed 1 year ago

AnderBiguri commented 1 year ago

The variable that indexes Voxels on the GPU is unsigned long long, which translates to 2^32. GPUs nowadays are bigger than that, an A6000 has 48GB of RAM, meaning that a 2048^3 image can fit fully, with 2^33 voxels.

We need to fix this.

Actually its 2^64, but there may be some issue in the creation of this index.

This is supposed to be solved, waiting for confirmation to close the issue
