Difference between voxel grid and fragment volume? #104

Open murrdpirate opened 2 years ago

murrdpirate commented 2 years ago

The fragment volume is defined as the cubic volume that encloses the view frustums (with each frustum having a max distance). Thus, this volume can change based on the specific view frustums.

But the voxel grid appears to have a fixed size: e.g. 96 voxels in each dimension with a voxel size of 0.04 m.

Is the voxel grid aligned with the min corner of the fragment volume, but with a potentially different max corner?
