ABSTRACT:
An image to be clipped is decomposed into its edges and the edges simultaneously clipped by multiple execution units of a SIMD computer along pairs of parallel clip planes. Successive parallel operations are performed on polygons recomposed using the clipped output edges, until all clipping has been performed.
