Non-Orthogonal Reduction for Rendering Fluorescent Materials in Non-Spectral Engines
Alban Fichet, Laurent Belcour, Pascal Barla
We propose a method to accurately handle fluorescence in a non-spectral (\eg, tristimulus) rendering engine, showcasing color-shifting and increased luminance effects. Core to our…
Transforming a Non-Differentiable Rasterizer into a Differentiable One with Stochastic Gradient Estimation
Thomas Deliot, Eric Heitz, Laurent Belcour
We show how to transform a non-differentiable rasterizer into a differentiable one with minimal engineering efforts and no external dependencies (no Pytorch/Tensorflow). We rely on…
Iterative -(de)Blending: a Minimalist Deterministic Diffusion Model
Eric Heitz, Laurent Belcour, Thomas Chambon
We derive a minimalist but powerful deterministic denoising-diffusion model. While denoising diffusion has shown great success in many domains, its underlying theory remains largel…
A Data-Driven Paradigm for Precomputed Radiance Transfer
Laurent Belcour, Thomas Deliot, Wilhem Barbier +1
In this work, we explore a change of paradigm to build Precomputed Radiance Transfer (PRT) methods in a data-driven way. This paradigm shift allows us to alleviate the difficulties…
