[Feature Request] Request for Implementing a Differentiable Voxelization Method in Spconv

[Uzuki Ishikawajima]

Dear traveller59,

I hope this message finds you well. We would like to express our sincere appreciation for your outstanding contribution. Recently, we have been engaged in robustness research on voxel-based networks.
In our endeavors, we have encountered the necessity for gradients of individual points within point clouds. It has come to our attention that Spconv currently lacks the implementation of a differentiable voxelization method. This prompts us to inquire whether there might be a possibility to implement such a feature into Spconv?

We would be immensely grateful for any guidance or insights you could provide on this matter.

Thank you for your time and consideration.

Regards,

Uzukid Ishikawajima
