Pipeline

A series of steps that a graphics [[API]] (such as [[wgpu]]) uses to convert [[vertices]] into an on-screen image.

High-level steps:

1. Vertex Fetching: Vertices are loaded from buffers.
2. Vertex Shading: Vertices are processed by a vertex [[vertex shader]].
3. Primitive Assembly: Vertices are assembled into geometric [[Primitive State|primitive]] (such as triangles).
4. Rasterization: The [[Primitive State|primitives]] are converted into pixels.
5. Fragment Shading: Pixels are processed by a [[fragment shader]] to produce colors.
6. Blending and Output: Colors are blended in the [[framebuffer]].
