3D Grid Generator and differentiability #25

Closed v-prgmr closed 4 years ago

v-prgmr commented 4 years ago

Greetings,

I was going through your paper. I would like to know about the 3D Grid Generator. You mention in the paper that the 3D point cloud projection to 2D space is carried out differentiably.

Could someone point out where I can look for this portion in the code?

Thank you

you mean that how to generate 3D point from 2D space? if so, I think it's in code/common/all_transformer.py _3D_meshgrid_batchwise_diff

@oishigyunyu, thank you (y)
