ABSTRACT
Light transport simulation is ruled by the radiance equation, which is an integral equation. Photorealistic image synthesis consists of computing functionals of the solution of the integral equation, which involves integration, too. However, in meaningful settings, none of the integrals can be computed analytically and, in fact, all these integrals need to be approximated using Monte Carlo and quasi-Monte Carlo methods. Generating uniformly distributed points in the unit-hypercube is at the core of all of these methods. The course teaches the algorithms behind and elaborates on the characteristics of different classes of uniformly distributed points to help selecting the points most efficient for a task.

Deep image-based relighting from optimal sparse samples
We present an image-based relighting method that can synthesize scene appearance under novel, distant illumination from the visible hemisphere, from only five images captured under pre-defined directional lights. Our method uses a deep convolutional ...
A few good samples: shape & tone depiction for Hermite RBF implicits
NPAR '10: Proceedings of the 8th International Symposium on Non-Photorealistic Animation and RenderingWe present techniques for rendering Hermite Radial Basis Function (HRBF) Implicits in different pen-and-ink styles. HRBF Implicits is a simple and compact representation, providing three fundamental qualities: a small number of point-normal samples as ...
Stylized Rendering Using Samples of a Painted Image
We introduce a novel technique to generate painterly art map (PAM) for 3D non-photorealistic rendering. Our technique can automatically transfer brush stroke textures and color changes to 3D models from samples of a painted image. Therefore, the ...
