The effects of lighting and resulting shadows within a computer simulated three-dimensional scene are modeled by rendering a light depth image and a light color image for each of the light sources. The light depth images are compared to a camera depth image to determine if a point within the scene is lighted by the various light sources. An accumulated light image is produced by combining those portions of the light color images determined to be lighting the scene. The resulting accumulated light image is then combined with a camera color image to produce a lighted camera image that can be further processed and eventually displayed on a computer display screen. The light color image can be static or dynamic. Transformations between different perspective and/or coordinate systems can be precalculated for fixed cameras or light sources. The various images and manipulations can include individual pixel data values, multiple-pixel values, polygon values, texture maps, and the like.

The light depth data is compared to a camera depth data to determine if a point within the scene is lighted by the various light sources. Accumulated light data is produced by combining those portions of the light color images determined to be lighting the scene and stored in the frame buffer. The resulting accumulated light data is then combined with a camera color image to produce a lighted camera image that can be further processed and eventually displayed on a computer display screen. The light color image can be static or dynamic. The various images and manipulations can include individual pixel data values, multiple-pixel values, polygon values, texture maps, and the like.

An exercise therapy video game and monitor system for mentally and physically stimulating an individual. More specifically, the system includes a whole-body fitness program that integrates motion, motor-sensory learning, and vision using games and motion sensing technology to track video-directed body position and movements of the individual. The system includes at least a first gaming platform, interactive exercise software to provide movement instructions to the individual, a computing system, and one or more sensors, such as motion sensors or sensors associated with a mat, to track body positions and movements of the individual. The system can then provide instant feedback to improve the body positions and movements of the individual to better replicate video directions.
