Differentiable Shadow Mapping for Efficient Inverse Graphics

1 code implementation CVPR 2023 Markus Worchel, Marc Alexa

We show how shadows can be efficiently generated in differentiable rendering of triangle meshes.

Super-Fibonacci Spirals: Fast, Low-Discrepancy Sampling of SO(3)

no code implementations CVPR 2022 Marc Alexa

Super-Fibonacci spirals are an extension of Fibonacci spirals, enabling fast generation of an arbitrary but fixed number of 3D orientations.
