1. A graphics subsystem, comprising: a geometry processor configured to receive input vertex data and process the input vertex data received to produce vertex data output; a resampler configured to receive the vertex data output of the geometry processor and to generate a resampler output responsive to the vertex data output received; a fragment processor configured to receive the resampler output, to modify the resampler output and to generate a fragment processor output responsive to the resampler output received; and a raster analyzer configured to receive the fragment processor output and to generate processed vertex data as output in a format compatible with the geometry processor.
