Many applications ranging from quasi-Monte Carlo integration over optimal control to neural networks benefit from high-dimensional, highly uniform samples. In the case of computer graphics, and more particularly in rendering, despite the need for uni

We present a method to implement quadtrees on the GPU. It relies on linear trees, a pointer-free alternative to recursive trees, that represents nodes as bit codes. We explain how to update this data structure with node splitting and merging, and sho

We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of microfacets may be retrieved b
