Massive difference between stage3 psnr and the resulting mesh
Hey there,
I was using MobileNeRF to use on my own dataset. It works well with the default settings with a good mesh that I can render using the ThreeJS viewer.
However I am facing a problem when trying to tweak the parameters. I wanted a lightweight mesh, so I tried setting
point_grid_size = 48
. This reduces the PSNR from 32-ish to the 28dB area which is is fine.
However when I extract the mesh, it is not the 28db quality that was promised. While the pred_frames.pkl
images look right, the rendered mesh itself is quite poor.
Here are the changes I made in stage3.py
to extract the mesh:
- Change
point_grid_size = 48
- Changed the texture size from
1024*2
to1008*2
. The 1008 comes from the fact thatquad_size*layer_num == texture_size
so I chose the closest multiple of 48.
Any hints to what might be going wrong?
