Line 138 in b6e0804

const float scale = exp2f(level * S) * H - 1.0f;

What's the difference between scale and resolution? Shouldn't they both refer to the number of voxels along one dimension?

And here you are trying to get the voxel center, why do you add 0.5 when align_corners is false?

Line 148 in b6e0804

pos[d] = inputs[d] * scale + (align_corners ? 0.0f : 0.5f);

@Guptajakala Hi, scale is float and resolution is int, it follows the original implementation's notation.
For the second one, you may refer to this.

Possible bug and difference between scale and resolution?
