WebApr 7, 2024 · Depth testing allows GPUs that have “Early-Z” functionality to reject geometry early in the pipeline, and also ensures correct ordering of the geometry. … WebGraphics hardware can perform early depth-based culling of fragments before computing their color value (in other words, before running your fragment shader). Consequently, if you utilize any features that would affect that, such as discard, alpha-testing, or manipulating gl_FragDepth the hardware's ability to do that optimization will be compromised since the …

Fragment discard and early fragment tests in practice

WebTo ensure early depth test rejection is used effectively, it is important for games to submit all draws that write to the depth buffer first. Doing so builds up the contents of the depth buffer so that early depth testing can reject subsequent obscured fragments.

WebThis will also perform early stencil tests. There is a caveat with this. This feature cannot be used to violate the sanctity of the depth test. When this is activated, any writes to gl_FragDepth will be ignored.The value written to the depth buffer will be exactly what was tested against the depth buffer: the fragment’s depth computed through rasterization.

WebThe Early Depth-Test then compares the z-value of each pixel that is about to be drawn with the ones that have already been drawn. If it determines the pixel would fail the Depth-Test and get discarded, it just discards it right then, before the pixel shader does any work on it. If the Early Depth-Test didn't exist the pixel would have been ...
