What's the normalization method of shapenetcore v2?

0 votes

On the wedsite, it notes: the preliminary ShapeNetCore v2 was incomplete and had different normalization than ShapeNetCore v1. Could you tell me more details about the normalization method? And what is the diagonal normalization in shapenetcore v1?

I couldn't find this info either but I found that the diagonal of the bounding box of the mesh vertices has length close to 1.

For shapenet v2, 

v_norm = (v-centroid) / norm(diag),


  • 'centroid' is the mean point of all vertices of the mesh
  • 'diag' is the diagonal vector of the bounding box

The normalization scripts are here:

Hello, jianfeiguo. Is there a code of shapenet v1 normalization?
