Abstract
A volume data set composed of voxels is rendered onto an image plane composed of pixels by casting a ray through each pixel of the image plane. A surface of the volume data set is selected as a base plane. Sample points are defined along each ray so that the sample points lie in planes parallel to the base plane. Voxels adjacent to each sample point are sampled to determine a sample value for each sample point, and the sample values of each ray are combined to determine a pixel value for each pixel.
