Abstract
Volume rendering lighting using dot product methodology is disclosed. In one embodiment of the invention, a computer includes a processor, a computer-readable medium and a computer program. The medium stores first data representing a set of voxel data representing an object, each voxel datum having a gradient that is desirably either positive or negative, and second data representing a light source having a directional vector. The computer program is executed by the processor from the medium, and displays the set of the voxel data, including illuminating each voxel datum using a dot product of the gradient of the voxel datum with the directional vector of the light source.
