A method to improve the performance of rendering image data (402) by converting what would normally be considered resolution-dependent image behavior into behavior that is substantially resolution-independent. This allows significant performance improvement since the rendering (454) can be performed on the lower-resolution image data used, for example, for on-screen viewing and when the image effect is applied to a higher resolution rendering, the effect, as viewed, is substantially the same as the effect viewed at a lower resolution. This conversion of normally resolution-dependent behaviors into pseudo-resolution-independent behaviors also allows the image effects to be applied to be carried out on a lower resolution image with confidence that when the image is rendered at a higher resolution that the image effects applied will substantially have the same appearance that the effect had at the lower resolution.

Systems and methods for producing an acceleration structure provide for subdividing a 3-D scene into a plurality of volumetric portions, which have different sizes, each being addressable using a multipart address indicating a location and a relative size of each volumetric portion. A stream of primitives is processed by characterizing each according to one or more criteria, selecting a relative size of volumetric portions for use in bounding the primitive, and finding a set of volumetric portions of that relative size which bound the primitive. A primitive ID is stored in each location of a cache associated with each volumetric portion of the set of volumetric portions. A cache location is selected for eviction, responsive to each cache eviction decision made during the processing. An element of an acceleration structure according to the contents of the evicted cache location is generated, responsive to the evicted cache location.

To reorder the states, a score is computed and assigned to each of the states. Next, the states are sorted according to their computed scores.

The sum of the scores in each row of the table is representative of the score for the associated current state associated with that row. The states are sorted according to their score and a new state transition table is generated in accordance with the reordered states.

In an embodiment, each crosspoint contains an internal queue, which can store one or more packets to be touted. Traffic rates to be realized between all Input / Output (IO) pairs of the switch are specified in an N×M traffic rate matrix, where each element equals a number of requested cell transmission opportunities between each IO pair within a scheduling frame of F time-slots.
