Abstract
Examples described herein relate to rendering a full resolution image using a reduced resolution depth pre-pass to pre-populate depth data for culling. A computing device may include a memory, a graphics processing unit (GPU) including a hierarchical depth buffer or full resolution depth data, and at least one processor. The computer device may render an occlusion geometry at a reduced resolution. The computer device may be configured to sample a depth value of pixels of the occlusion geometry. The computer device may pre-populate the GPU depth data based on the sampled depth values. The computer device may cull at least one tile or pixel from a full resolution rendering process in response to a depth of the at least one tile or pixel being further than a corresponding depth value in the GPU depth data. The computer device may perform the full resolution rendering process on remaining tiles or pixels.
