tri-grid projection #28

Closed oneThousand1000 closed 1 year ago

oneThousand1000 commented 1 year ago

Hello, thank you for sharing your interesting work!

The authors of EG3D mentioned that their triplane projection is actually a bi-plane projection (XY, XZ, ZX) (see https://github.com/NVlabs/eg3d/issues/67). After examining your code, it seems that this issue is still present. I'm wondering if you have considered the potential problems that may arise from this projection method in the proposed tri-grid?

I look forward to your kind reply!

We already considered and fixed it:

https://github.com/SizheAn/PanoHead/blob/main/training/volumetric_rendering/renderer.py#L15-L29

The tri-plane projection here is XY, XZ, YZ, whereas in your link the fix Eric provided is XY, XZ, ZY. They are essentially the same.
