ABSTRACT:
A method apparatus, and software product generates raster-based complete outlines of raster-based rendered images based on 3D models. Preliminary outlines of a rendered image are created from the subregion identifiers, position data, and orientation data from the rendered image database. These preliminary outlines are then combined and refined to generate the final image outline. Subregion identifiers identify various subregions or materials in the image. Position data describes a distance between a pixel and a reference point. The orientation data describes the orientation of the underlying models at each pixel in the image. In one embodiment, orientation data describes variations in orientation at a given pixel with respect to some number of nearby pixels.
