Can we extend when input resolution(voxel_size) is different in xyz dimensions?

[synsin0]

I see both gt_dist and pred_dist are multiplied with voxel_size after, what if voxel size is different on xyz dimensions?

You can have different resolutions across all three axes!

First of all, the cuda kernel is independent of the voxel resolutions. It only thinks of a grid as cells with integer-valued indices.

Second, the multiplication of gt_dist with voxel_size of 0.2 is actually a multiplication with $\frac{\sqrt{0.2^2 + 0.2^2 + 0.2^2}}{\sqrt{1^2 + 1^2 +1^2}}$. You could instead have different resolutions with different axes and multiply gt_dist and pred_dist with $\frac{\sqrt{v_x^2 + v_y^2 + v_z^2}}{\sqrt{1^2 + 1^2 +1^2}}$. Let me know if you try this!
