Abstract
An image generator computes a set of light sample points, wherein each light sample point is a point on a light source from a geometric model, and an irradiance image is computed for each light sample point, wherein an irradiance image is a view-dependent image taken with the light sample point being the view point and the light source for the irradiance image. From the irradiance images, the image generator creates an irradiance texture for each object in a set of objects being considered the scene and the image generator renders the image of the objects in the set of objects with each object's coloring determined, at least in part, from the object's irradiance texture. Depending on performance requirements, one or more operation of the image generator is parallelized.
