摘要:
Methods and systems may provide for identifying a plurality of subject commands that reference a common screen location and access a read/write resource, and serializing the plurality of subject commands according to a predefined order. Additionally, execution of the plurality of subject commands may be deferred until one or more additional commands referencing the common screen location are executed. In one example, the plurality of subject commands are serialized in response to a serialization command.

The problem of generating high quality images with a rendering pipeline based on decoupled sampling may be addressed by generating non-extrapolated shading locations and by determining improved texture filtering footprints. This may be accomplished by performing shading at the center of a bounding box that bounds mapped shading samples.
摘要:
Representing a transparent object as a summation of substantially zero step functions of a visibility curve for the object. An array may be used to store nodes to represent the visibility function. The size of the array may be limited to be storable within a memory of an on-chip graphics processing unit.

A dynamic volumetric medium, such as hair, fog, or smoke, may be represented, for purposes of shadow mapping, by transmittance versus depth data for that medium. In one embodiment, the representation may take the form of a plot of transmittance versus depth, with nodes where the transmittance changes non-live linearly with respect of depth into the medium. The number of nodes in the representation may be reduced to reduce memory footprint and to enable the storage of the representation on the same chip doing the shadow mapping. In some embodiments, the number of nodes may be reduced, one node at a time, by removing the node whose underlying trapezoid has the least area of all the remaining nodes.
