WebJan 4, 2024 · In line 11 a pixel format for the stencil testing is defined. Because depth and stencil testing have similar goals the context of both tests is stored in a single texture. In this case we define that every pixel uses 24 bits for the depth buffer and 8 bit for the stencil buffer. Lines 16-21 two wgpu::StencilFaceState for stencil testing: front ... A depth buffer, also known as a z-buffer, is a type of data buffer used in computer graphics to represent depth information of objects in 3D space from a particular perspective. Depth buffers are an aid to rendering a scene to ensure that the correct polygons properly occlude other polygons. Z-buffering was first described in 1974 by Wolfgang Straßer in his PhD thesis on fast algorithms for renderin…
