Abstract
Examples described herein relate to rendering an image using a reduced fidelity of shading for portions of a triangle that are potentially occluded by other objects. A computer device may pre-populate a potentially occluded depth map in a graphics processing unit (GPU) for a current frame based on depth data of a previous frame, a low resolution depth pre-pass, or a rasterizing occlusion geometry. The GPU may determine, at a rasterization stage, that a depth of a portion of a triangle being processed is further than a depth of a corresponding tile in the potentially occluded depth map. The GPU may decrease a fidelity of shading applied to at least the portion of the triangle in comparison to a specified fidelity for the triangle in response to determining that the depth of the portion of the triangle is further than the depth of the corresponding tile.
