Description
Simon Truempler's illustrated deep dive into the GPU raster pipeline for artists and technical artists, hosted on simonschreibt.de. Version 2.0 adds five book-length sections, new videos, dozens of curated links, and expanded coverage of copying data from storage to the graphics card.
Topics include draw calls, material batching, API state changes, vertex fetch, the logical graphics pipeline, SIMD warps, shader cores, rasterization, FIFO behavior, tessellation, guard-band clipping, overdraw, and engine batching notes for Unity and Unreal. Animated diagrams accompany articles from MSDN, GPU Gems, Kayvon Fatahalian's architecture talks, and vendor whitepapers.
Beginners without programming background can follow the artist-friendly explanations, though API-specific caveats remain. It helps tech artists discuss performance with engineers and gives programmers a visual map of hardware behavior.
