Abstract: Embodiment described herein combines a caching system with special cache flushing methods aimed at reducing thread divergence across a group of threads in a thread group, in order to synchronize branching paths taken by different threads executing on the same graphics processor execution unit, One embodiment provides for a graphics processing apparatus comprising graphics execution logic to execute one or more threads of a graphics shader program; an occluder cache to store input occluder node data for adaptive graphical effects logic of the graphics shader program; and compression logic to compress input occluder node data stored in the occluder cache. The occluder node data, in one embodiment, includes occlusion data for use with adaptive shadowing or transparency logic.

Abstract: An application binary interface includes a descriptor specifying a binary shader for each pass of a multi-pass shader. The application binary interface also includes a graphics state of a graphics object for each pass of the multi-pass shader. The graphics state for the first pass is an initial graphics state of the graphics object. The graphics state for each subsequent pass specifies a change from the graphics state of a previous pass. The application binary interface further includes parameters for the binary shaders. The application binary interface links the binary shaders together based on the parameters. Further, the parameters of the binary shaders may be modified at run time to configure the multi-pass shader. The binary shader of each pass is then executed based on the graphics state and parameters of the pass to render the graphics object.

Abstract: Different rendering techniques are selected for portions of a scene based on statistical estimates of the portions' rendering costs. A scene is partitioned into a bounding volume hierarchy. Each bounding volume includes a statistical model of the spatial distribution of geometric primitives within the bounding volume. An image to be rendered is partitioned into screen regions and each screen region is associated with one or more bounding volumes and their statistical models. The associated statistical models of a screen region are evaluated to estimate the rendering cost, such as the probable number of geometric primitives per pixel, for the screen region. Based on the rendering cost, the screen region is assigned to a dense geometry renderer, such as a ray tracing renderer, or a sparse geometry renderer, such as a rasterization renderer. Rendered screen regions are combined to form a rendered image.
