Harmonics Virtual Lights : fast projection of luminance field on spherical harmonics for efficient rendering

Autor: Pierre Mézières, François Desrichard, David Vanderhaeghe, Mathias Paulin

In this paper, we introduce Harmonics Virtual Lights (HVL), to model indirect light sources for interactive global illumination of dynamic 3D scenes. Virtual Point Lights (VPL) are an efficient approach to define indirect light sources and to evaluat

International audience; Spherical Harmonics (SH) are commonly and widely used in computer graphics in order to speed up the evaluation of the rendering equation. With separable BRDF, the diffuse and specular contributions are traditionally computed s

International audience; Computer graphics artists often resort to compositing to rework light effects in a synthetic image without requiring a new render. Shadows are primary subjects of artistic manipulation as they carry important stylistic informa

We propose a versatile pipeline to render B-Rep models interactively, precisely and without rendering-related artifacts such as cracks. Our rendering method is based on dynamic surface evaluation using both tesselation and ray-casting, and direct GPU
