Tessellation engine and applications thereof

摘要

Disclosed herein methods, apparatuses, and systems for performing graphics processing. In this regard, a processing unit includes a tessellation module and a connectivity module. The tessellation module is configured to sequentially tessellate portions of a geometric shape to provide a series of tessellation points for the geometric shape. The connectivity module is configured to connect one or more groups of the tessellation points into one or more primitives in an order in which the series of tessellation points is provided.

1. A graphics-processing method implemented in a processing unit, comprising:
sequentially tessellating a geometric shape to provide a first set of tessellation points from among a plurality of sets of tessellation points for the geometric shape; and connecting tessellation points of the first set into one or more primitives in an order in which the tessellation points of the first set is provided, wherein the connecting further comprises:
selecting a lookup table from a plurality of lookup tables to determine whether tessellation points of the first set of tessellation points are connected; andcreating a primitive of the one or more primitives in a single clock cycle by looping through the lookup table.
