Summary

Differentiate wrt light source position

Description

Hi! I would like to perform differentiable rendering in order to move a light source to match a GT image. I see that the parameter to_world is not differentiable, so I was wondering if you have an idea on how to do this, if there is something else regarding a light source position I could optimize for example. Any tip will help!

sorry was to quick asking this. The answer is on https://github.com/mitsuba-renderer/mitsuba2/blob/pathreparam-optix7/docs/examples/10_inverse_rendering/invert_pose.py

Anyway, thanks for the amazing project!
