Abstract
A moving or defocused geometry may be stochastically rendered by grouping a plurality of primitives of that geometry in a hierarchical data structure. Visible fragments may be located in that data structure by hierarchically traversing a ray frustum through the structure. A time-dependent ray tracing data structure may be used in some embodiments.
