Webbtorch.scatter_add () to multiple dimensions. I am trying to scatter a 2D point cloud i.e a list of 2-D points onto an image. Given points (B * 2 * N ), scatter them onto an image of size (B * H * W). While scattering more than one point can fall on the same image pixel, and the value corresponding to those points should be added.
