Description
Hi, here is the details. when bev voxel is not a square, the VT-transform with ring&ray method still work？ mainly about the step to simplify FLOPs in VT. cause i see the Comment in get_proj_mat
bev_size = int(self.voxel_num[0]) # only consider square BEV
thank you

Research direction
Start by locating get_proj_mat and tracing how voxel_num is used in the ring&ray VT transform and its FLOPs simplification. Determine whether rectangular BEV dimensions are supported or require design changes; the issue is done when the supported behavior and validation are established.
