coords and points

LiDaiY opened this issue · comments

Hello,
I am confused about the 'coords' and 'points'. I thought 'points' contain the XYZ, RGB and Normal. But I don't konw what does 'coords' represent. Looking forward your reply.

Hi @LiDaiY,

coords are the global coordinates of a scene, while points are the normalized coordinates in a block (in the range of [0, 1]). Later the method merges all of the blocks in a scene together for the MV-CRF step, hence it needs the global coordinates.

Thanks for your reply. I found data preprocessing scripts are in 'scripts' folders. I think I should read these codes for better understanding the data.
