Question about how you pick the point in your training data #79

Open Zhangsihao-Yang opened 6 years ago

Zhangsihao-Yang commented 6 years ago

You are using 2048 points in each of your training data. How could you pick them?

charlesq34 commented 6 years ago

Hi @Zhangsihao-Yang

We used mesh sampling code from here to overly sample more than 10k points and then use farthest point sampling to pick the 2048 points.

Hi, @charlesq34 , Would you also point the code of farthest point sampling? Where could we find the code for FRS?

Hi @amiltonwong

You can check it here: https://github.com/charlesq34/pointnet2/blob/master/tf_ops/sampling/tf_sampling.py
