Data-Driven Interactive Quadrangulation

摘要

We propose an interactive quadrangulation method based on a largerncollection of patterns that are learned from models manually designedrnby artists. The patterns are distilled into compact quadrangulationrnrules and stored in a database. At run-time, the userrndraws strokes to define patches and desired edge flows, and thernsystem queries the database to extract fitting patterns to tessellaternthe sketches’ interiors. The quadrangulation patterns are generalrnand can be applied to tessellate large regions while controlling thernpositions of the singularities and the edge flow. We demonstrate therneffectiveness of our algorithm through a series of live retopologyrnsessions and an informal user study with three professional artists.
