Noisy normal map in nerf_synthetic "materials" scene #6

Closed jpsml closed 3 months ago

jpsml commented 3 months ago

I executed the following experiment:

python -u train.py -s data/nerf_synthetic/materials/ --eval --iterations 61000 --white_background --densification_interval_when_prop 100

However, the obtained normal maps are a little bit noisy in the spheres with high specularity:

train_view_r_2_normal_map

I noticed that the obtained env maps are a little bit blurred:

env_cood1 env_cood2

Is this the expected result?

Our method does not model different roughness level and interreflections. Our method tends to first fit reflections with higher roughness, so the env. map looks a little bit blurred. Additionally, interreflections can affect normal reconstruction, resulting in poorer performance in the material scene.
