GPU mode yield inaccurate result

[CuberMessenger]

I just voxelized a simple cube, defined as (obj file):
v 150.100006 400.100006 550.099976
v 550.099976 400.100006 550.099976
v 150.100006 800.099976 550.099976
v 550.099976 800.099976 550.099976
v 150.100006 800.099976 150.100006
v 550.099976 800.099976 150.100006
v 150.100006 400.100006 150.100006
v 550.099976 400.100006 150.100006

f 1 2 4
f 1 4 3
f 3 4 6
f 3 6 5
f 5 6 8
f 5 8 7
f 7 8 2
f 7 2 1
f 2 8 6
f 2 6 4
f 7 1 3
f 7 3 5

The CPU mode generate fine result, but the GPU mode yield something inaccurate:




The first image is the voxelization result visualized by marching cubes algorithm and meshLab, some glitch appears along the diagonal line. The latter 3 images are 3 continuous 2-D plane of the voxelization result, the middle one shows that the glitches comes from the voxelizer.

I barely know about cuda programming and the voxelization algorithm, just point out this issue, maybe someone can fix it.
Still very nice voxelizer 😃 !

Yeah, I think this is an artifact of the bounding box of the model perfectly aligning with the model itself. Probably a numeric instability. Will look into it.
