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…
Bringing Linearly Transformed Cosines to Anisotropic GGX
Aakash KT, Eric Heitz, Jonathan Dupuy +1
Linearly Transformed Cosines (LTCs) are a family of distributions that are used for real-time area-light shading thanks to their analytic integration properties. Modern game engine…
Lessons Learned and Improvements when Building Screen-Space Samplers with Blue-Noise Error Distribution
Laurent Belcour, Eric Heitz
Recent work has shown that the error of Monte-Carlo rendering is visually more acceptable when distributed as blue-noise in screen-space. Despite recent efforts, building a screen-…
Passing Multi-Channel Material Textures to a 3-Channel Loss
Thomas Chambon, Eric Heitz, Laurent Belcour
Our objective is to compute a textural loss that can be used to train texture generators with multiple material channels typically used for physically based rendering such as albed…
A Sliced Wasserstein Loss for Neural Texture Synthesis
Eric Heitz, Kenneth Vanhoey, Thomas Chambon +1
We address the problem of computing a textural loss based on the statistics extracted from the feature activations of a convolutional neural network optimized for object recognitio…
Integration and Simulation of Bivariate Projective-Cauchy Distributions within Arbitrary Polygonal Domains
Jonathan Dupuy, Laurent Belcour, Eric Heitz
Consider a uniform variate on the unit upper-half sphere of dimension . It is known that the straight-line projection through the center of the unit sphere onto the plane above…
