A shadow rendering method, the method comprising the steps of: providing observer data of a simulated multi-dimensional scene; providing lighting data associated with a plurality of simulated light sources arranged to illuminate said scene, said lighting data including light image data; for each of said plurality of light sources, comparing at least a portion of said observer data with at least a portion of said lighting data to determine if a modeled point within said scene is illuminated by said light source and storing at least a portion of said light image data associated with said point and said light source in a light accumulation buffer; and then combining at least a portion of said light accumulation buffer with said observer data; and outputting resulting image data. view more

A computer-readable medium carrying at least one set of computer instructions configured to cause at least one processor to operatively render simulated shadows in a multi-dimensional simulated scene by performing the steps of: providing observer data of a simulated multi-dimensional scene; providing lighting data associated with a plurality of simulated light sources arranged to illuminate said scene, said lighting data including light image data; for each of said plurality of light sources, comparing at least a portion of said observer data with at least a portion of said lighting data to determine if a modeled point within said scene is illuminated by said light source and storing at least a portion of said light image data associated with said point and said light source in a light accumulation buffer; and then combining at least a portion of said light accumulation buffer with said observer data; and outputting resulting image data. view more

A computer circuit for processing computer graphics data coupled to a computer system to operatively render simulated shadows in a multi-dimensional simulated scene by performing steps comprising: a) receiving observer data of a simulated multi-dimensional scene; b) receiving lighting data associated with a plurality of simulated light sources arranged to illuminate said scene, said lighting data including light image data; c) for each of said plurality of light sources, comparing at least a portion of said observer data with at least a portion of said lighting data to determine if a modeled point within said scene is illuminated by said light source and storing at least a portion of said light image data associated with said point and said light source; d) combining at least a portion of said light image data with said observer data; and e) transmitting resulting image data for display on a computer screen. view more
