Variants
A hybrid between this and Z-buffering does away with the active edge table sorting, and instead rasterizes one scanline at a time into a Z-buffer, maintaining active polygon spans from one scanline to the next.
In another variant, an ID buffer is rasterized in an intermediate step, allowing deferred shading of the resulting visible pixels.
