Abstract
Splat lights apply environmental lighting effects to objects in a scene. Splat light sources bypass all or a majority of the operations of a shader program. The rendered color of an object due to the splat light is specified directly by the color of the splat light. A splat light includes a color, a direction, and an angular range. The illumination of a point on an object from a splat light is determined by a normal vector at that point. The splat light contributes no illumination to points that have normal vectors outside of the angular range of the splat light. Because splat lights specify the illuminated color and intensity of points directly, splat lights produce predictable and consistent illumination on objects. Splat lights can be specified with a user interface that displays splat light indicators positioned on an environmental lighting framework.
