Abstract
A computer-implemented method for generating a shadow in a graphics scene. The method includes casting a ray having a finite length associated with a point on a surface of an object in the graphics scene towards a light source; determining whether the ray intersects any other objects in the graphics scene; and generating a shadow value associated with the point on the surface of the object based on a combination of geometric scene information obtained as a result of determining whether the ray intersects any other objects in the graphics scene and an image-based shadow map value.
