Patent ID: 7650588

Claim:
A pattern generation method for increased fidelity and/or improved focus of computer processing power, the method comprising: receiving, at a data preparation module of a pattern generation system, design data describing a pattern to be generated; processing, by the data preparation module, the received design data to generate a non-overlapping polygon representation of the design data; generating, by the data preparation module, metadata from the non-overlapping polygon representation, wherein the metadata is associated with the pattern in an unfractured format, and wherein the metadata includes properties associated with at least one of corners and edges of the pattern; fracturing, by the data preparation module, the non-overlapping polygon representation; and transmitting, by the data preparation module in parallel with one another, the fractured non-overlapping polygon representation and the metadata to a pattern generator adapted for generating the pattern based on the fractured non-overlapping polygon representation and metadata including at least one of corner and edge properties associated with the pattern in an unfractured format.
