Hello. Thank you for your excellent work. I would like to know how you handle gaussians that fall on the same grid during sparse convolution.

Hey, Not 100% sure about this but I think most of the traditional librairies compute the mean of features falling in the same voxel.

Hello, If this is the case, different positions of Gaussians may result in the same features, or how are the sparse features obtained from self-encoding utilized? I feel that the article does not make this clear. Could you help me?

Sorry for the late reply. We used implementation from spconv. Please check model/encoder/gaussian_encoder/spconv3d_module.py for more details.
