One embodiment of the present invention sets forth a technique for splitting a set of vertices into a plurality of batches for processing. The method includes receiving one or more primitives each containing an associated set of vertices. For each of the one or more primitives, one or more vertices are gathered from the set of vertices, the vertices are arranged into one or more batches, the batch is routed to a processing pipeline line to process each batch as a separate primitive, and the one or more batches are processed to produce results identical to those of processing the entire primitive as a single entity.
