About

This repository contains code to reproduce the figures of the paper "Radiative Backpropagation with Non-Static Geometry". The implementation is based on the differentiable renderer Mitsuba 3.

• case_1_indirect_from_spatially_varying_emitter.ipynb: Code for Figures 1, 2, 3.
• case_2_cornell_box.ipynb: Code for Figures 4, 5, 6.
• moving_path_inset.ipynb: Code for the inset "non-static geometry moves a path".
