ShapeNet normalization #10

Closed jatentaki closed 1 year ago

jatentaki commented 1 year ago

When you mention global normalization to [-1, 1] in table 1 and per-example normalization to [-1, 1] in table 2, which flags on ShapeNet15kPointClouds does that correspond to? I'm thinking about the combination of normalize_per_shape, normalize_shape_box, normalize_std_per_axis and normalize_global. Thank you.

it's normalize_shape_box

jatentaki commented 1 year ago

Thank you for your answer. I assume normalize_shape_box=True refers to table 2, but what about table 1? Setting all the flags to False results in an exception coming from here.

ZENGXH commented 1 year ago

yes. Table 1 using normalize_global=True.
