VISIBILITY-BASED STATE UPDATES IN GRAPHICAL PROCESSING UNITS |
摘要 |
In general, techniques are described for visibility-based state updates in graphical processing units (GPUs). A device that renders image data comprising a memory configured to store state data and a GPU may implement the techniques. The GPU may be configured to perform a multi-pass rendering process to render an image from the image data. The GPU determines visibility information for a plurality of objects defined by the image data during a first pass of the multi-pass rendering process. The visibility information indicates whether each of the plurality of objects will be visible in the image rendered from the image data during a second pass of the multi-pass rendering process. The GPU then retrieves the state data from the memory for use by the second pass of the multi-pass rendering process in rendering the plurality of objects of the image data based on the visibility information. |
