Abstract: An apparatus to facilitate variable rate shading is disclosed. The apparatus comprises one or more processors to generate a course pixel output value for a pixel block, generate a gradient value comprising a gradient of the course pixel output value using neighbor pixel data and process the pixels in the pixel block using the gradient value to generate a fine pixel value for one or more pixels.

Abstract: Apparatus and method for temporally stable conservative morphological anti-aliasing. For example, one embodiment of a method comprises: rendering a current frame in a graphics processing apparatus, the current frame including color components and depth components; detecting edges within the rendered frame to generate a first set of edge candidates and a second set of edge candidates; performing spatial anti-aliasing using the first set of edge candidates; and performing temporal anti-aliasing using the second set of edge candidates.

Abstract: An apparatus and method for performing multisampling anti-aliasing. For example, one embodiment of an apparatus samples multiple locations within each pixel of an image frame to generate a plurality of image slices. Each image slice comprises a different set of samples for each of the pixels of the image frame. Anti-aliasing is then performed on the image frame using the image slices by first subdividing the plurality of image slices into equal-sized pixel blocks and determining whether each pixel block has one or more different pixel values in different image slices. If so, then edge detection and simple shape detection is performed using pixel data from a pixel block in a single image slice; if not, then edge detection and simple shape detection is performed using the pixel block in multiple image slices.

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.
