We present prefiltered neural fields that output filtered signals in a single forward pass by analytically scaling Fourier-feature embeddings with the filter’s frequency response and training with a single-sample Monte Carlo estimate; the modulation generalizes from Gaussian to Box and Lanczos at test time.

We propose a novel Factorized Inverse Path Tracing (FIPT) method which utilizes a factored light transport formulation and finds emitters driven by rendering errors.

We propose a data-driven fiducial marker system tailored for deformed surfaces. Thanks to training based on photorealistic differentiable rendering, our markers enable applications such as motion capture and structured light.
