Abstract
There is provided a system and a method for ordering rays in rendered graphics for coherent shading. The method comprises recording, using the processor, intersection points for each of a plurality of directional queries in the memory, wherein each of the plurality of directional queries has one intersection point, organizing, using the processor, the intersection points in the memory into a plurality of elements, and grouping, using the processor, the intersection points in the memory by shading context. The method may further comprise shading the intersection points, wherein the shading is performed on a plurality of elements substantially concurrently. The shading context may include a volume of intersection points. In another implementation, the shading context may be one of texture ID, material ID, and element ID. Additionally, the texture ID may correspond to a mesh face ID.
