rasterizer / rasterization
The process of converting shapes into fragments (pixel-sized pieces) for the GPU to color in.
Rasterization is the act of scan-converting primitives into fragments: determining coverage, interpolating per-vertex values, and emitting one fragment per covered pixel for shading. It is the heart of real-time graphics and, in this stack, a heavily-worked component of the mzVolk renderer. The rasterizer is the hardware/software unit that performs it.
