Abstract: Aspects comprise a ray tracing shadowing method based on the data structure of a uniform grid of cells, and on local stencils in cells. The high traversal and construction costs of accelerating structures are cut down. The object's visibility from the viewpoint and from light sources, as well as the primary workload and its distribution among cells, are gained in the preprocessing stage and cached in stencils for runtime use. In runtime, the use of stencils allows a complete locality at each cell, for load balanced parallel processing.

The salience of a physically significant detail may be controlled via a threshold value which may be user or system specified.
