COMPUTING REPRESENTATIVE SHAPES FOR POLYGON SETS

摘要

A technique for efficiently processing sets of shapes is executed by one or more processors. The technique includes receiving a description of a set of shapes, the description including an indication of geometry for each of the shapes and an indication of positioning of the shapes relative to each other; generating a connected graph containing each shape in the set to define an ordered list; for each pair of shapes adjacent to each other in the connected graph, generating a respective convex hull enclosing the pair of shapes; generating a representative shape for the set of shapes, the representative shape enclosing each of the generated convex hulls; and operating on the generated representative shape to perform an operation related to the set of shapes.
