Question for the paper #4

Open SYSUykLin opened 3 months ago

SYSUykLin commented 3 months ago

Great paper, but I have some questions.

1) Is it necessary to learn physical properties from dynamic scenes? Why can't we just assume the force between anchors? Or just apply gravity? 2) Have u try other complex scene? For example, tank and temples datasets.

Thanks!

Hi, thanks for the questions,

  1. I think learning physical properties is significant to reduce domain gap for sim-to-real.
  2. I haven't tried this method on complex data yet, and I think it will be an extremely hard task in complex scene.
