Abstract
Method, system, and computer-readable storage medium for flattening 3D patches of a 3D graphics model. For each vertex in each polygon of a plurality of polygons of a 3D patch from a 3D graphics model, a vector is determined from a seed point of the 3D patch to the vertex. An axis in a plane of the polygon that includes the seed point and is perpendicular to the vector is determined, and the vector rotated around the axis until the vector is in the plane of the polygon to generate a corresponding 2D vertex at the endpoint of the rotated vector in the plane. The determining a vector, determining an axis, and rotating the vector for each vertex in each polygon of the 3D patch generates a 2D patch of co-planar polygons corresponding to the polygons of the 3D patch, which is stored for use in a computer graphics application.
