partial point clould completion application

[Zhengxinyang]

If I have only one partial point cloud and want to do forward with your pre-trained model, how do I adjust the scale and center of the partial point cloud?

[yuxumin]

centering (by subtracting the mean coordinates) and scaling it according to the training samples of the pretrained PoinTr. PoinTr-ShapeNet55 is roughly [-1, 1], PoinTr-PCN is roughly [-0.5, 0.5])
