METHODS OF ELIMINATING REDUNDANT RENDERING OF FRAMES

摘要

A method for reducing redundant rendering of frames includes receiving draw calls including state information for a frame. The method includes generating respective bounding boxes for the draw calls. The bounding box is generated based on vertex data, vertex programs and transformation matrices. The method includes comparing the draw calls of the frame to the draw calls of one or more previous frames and identifying draw calls that are not identical in the compared frames. The method includes identifying the bounding boxes containing altered regions of the frames based on the draw calls that are not identical in the compared frames. The method includes reducing the altered regions into a smaller set of clip rectangles and rendering only inside the clip rectangles.

1. A method of reducing redundant rendering of frames, comprising:
receiving draw calls including state information for a frame; generating respective bounding boxes for the draw calls, wherein the bounding boxes are generated based on vertex data, vertex programs and transformation matrices; comparing the draw calls of the frame to the draw calls of one or more previous frames; identifying draw calls that are not identical in the compared frames; identifying the bounding boxes containing altered regions of the frames based on the draw calls that are not identical in the compared frames; and rendering only inside the altered regions.
