Alias-Free Shadow Maps
(The Eurographics Association, 2004)
In this paper we abandon the regular structure of shadow maps. Instead, we transform the visible pixels P(x, y, z) from screen space to the image plane of a light source P0(x0, y0, z0). The (x0, y0) are then used as sampling ...
Hemispherical Rasterization for Self-Shadowing of Dynamic Objects
(The Eurographics Association, 2004)
We present a method for interactive rendering of dynamic models with self-shadows due to time-varying, lowfrequency lighting environments. In contrast to previous techniques, the method is not limited to static or preanimated ...
