about impact of scale #60

Dear Author, Thank you for open-sourcing. I have tried semseg-pt-v3m1-0-base on scannet. Then I tried to use my custom point cloud dataset, but I found it's scale is different from scannet(e.g. the range of coord is much smaller). According to class Point(Dict) described, my properties of a batched point cloud include coord、grid_size、offset and feat. For coord, I found it's useful to adjust grid_size, but for different scale of feat, is the any parameter I can adjust?

Kindly remind that the range of color (contained by feat) is [-1, 1] (normalized)
