Abstract
Techniques for illuminating an indoor scene. A directional distribution associated with the indoor scene is received. The indoor scene has a first scene element and a first quadrilateral. The first scene element has a first shading point disposed thereon. The directional distribution is reparametrized such that the first quadrilateral as viewed from the first shading point corresponds to an axis-aligned rectangular region in the reparametrized directional distribution. The scene element is illuminated using one or more samples drawn from the shading point by performing importance sampling based on the reparametrized directional distribution.
