Programmable Graphics Pipeline
The GPU processes draw calls through fixed stages (vertex fetch, rasterization, per-sample operations) interleaved with programmable stages (vertex and fragment shaders); the application configures state and supplies shader programs rather than issuing per-pixel commands. WebGL 2 exposes this pipeline: data flows one way, vertices in, fragments out, framebuffer written.
This Concept is waiting for its first lesson!
