Coordinate of the Scene (World Coordinate) #115

Closed MingleiDenso closed 2 years ago

MingleiDenso commented 2 years ago

Thanks so much for your comments inside code, that makes my reading so easy !

However, I am still struggled with the coordinate of the scene.

I found that the coordinate of the scene is [right up back] based on https://github.com/bmild/nerf/issues/34#issuecomment-616175083 (Edit: I think [right up back] here means camera coordinate according to README?)

However, I found it actually the orientation is different from [right up back] ? For example in the function create_spheric_poses, it looks like z axis is not back but up... I am a little lost here. Could you please give some idea ? Thank you !

I think I found the World Coordinate is [Left back Up]
