Patent ID: 8462147

Claim:
Enacted in a mega-mesh editing tool of a computer system, a method for sculpting a three-dimensional, graphical environment, comprising: receiving structure data that structurally defines the graphical environment in three dimensions at a first resolution; storing composite data based on the structure data received, the composite data comprising a first subset defining the graphical environment at the first resolution; exporting section-localized data based on the composite data to a three-dimensional sculpting tool external to the mega-mesh editing tool, the sculpting tool configured to output three-dimensional coordinates of a plurality of vertices of a plurality of polygons spanning a section, the section-localized data defining the section of the graphical environment at least structurally; receiving from the three-dimensional sculpting tool refined section-localized data defining the section of the graphical environment at a second resolution finer than the first resolution; augmenting the composite data to include a second subset, which, in combination with the first subset, defines at least the section at the second resolution, according to the refined section-localized data received.
