Strange sampling of voxels. #2

Open ddutchie opened 5 years ago

ddutchie commented 5 years ago

I have noticed that there are some strange artifacts when objects are touching, almost as if the last possible voxel for that object is not being traced.

Looking into this, but have already managed to implement material sampling with an extra matrix4x4 buffer containing the material info.

It looks like it has to do with an objects scale. If the plane's scale on the x and z is above 1 issues occur

I'll check it out

Thank you! Another example of some of the artifacts:

I'll add an example scene with the issues to my branch

should be fixed, let me know

ddutchie commented 5 years ago

Much better, although I still get some issues with small triangles?

Any ideas why this would be happening?
