In one aspect, the invention provides improvements in a digital data processor of the type that renders a three-dimensional (3D) volume image data into a two-dimensional (2D) image suitable for display. The improvements include a graphics processing unit (GPU) that comprises a plurality of programmable vertex shaders that are coupled to a plurality of programmable pixel shaders, where one or more of the vertex and pixel shaders are adapted to determine intensities of a plurality of pixels in the 2D image as an iterative function of intensities of sample points in the 3D image through which a plurality viewing rays associated with those pixels are passed. The pixel shaders compute, for each ray, multiple iteration steps of the iterative function prior to computing respective steps for a subsequent ray.
