Abstract
A method for Monte Carlo volume rendering in accordance with the present teachings includes: (a) tracing a plurality of light rays into a scene containing volumetric data, the light rays configured for simulating global illumination; (b) randomizing the scattering location and direction of the plurality of light rays through the volume, wherein a common sequence of random numbers is used in order for the scattering direction of each of the plurality of randomized scattered light rays to be substantially parallel; (c) computing at least one trilinearly interpolated and shaded sample along each of the plurality of randomized scattered light rays based on stored volumetric data, wherein at least a portion of the stored volumetric data used in at least a portion of the computing is configured for coherent access; and (d) rendering the volume with global illumination based on a plurality of iterations of the tracing, the randomizing, and the computing. Systems for Monte Carlo volume rendering are described.
