The ordered stages that transform scene data into an image on a display.
What is a rendering pipeline?
A rendering pipeline is the ordered set of transformations that turns a scene description into an image.
A typical real-time pipeline processes application commands, vertices, primitives, rasterized fragments, shading, depth and blending before presenting a frame.
Why is it useful?
Breaking rendering into stages lets hardware parallelize work and lets developers replace selected stages with shaders or specialized techniques.
The pipeline also explains why a visual error may come from geometry, coordinates, textures, lighting, sampling, color management or presentation timing.
Modern pipelines
Rasterization and ray tracing can cooperate. Compute passes may perform culling, lighting, post-processing or reconstruction.
Frames are synchronized with the display through queues and presentation modes.
Future
Rendering pipelines will become more heterogeneous and data-driven, with neural reconstruction and increasingly direct control over scheduling and memory.
The essential discipline remains making each transformation explicit enough to test and reason about.
