Abstract: One embodiment of the invention is a collage engine that generates informative viewpoints of a 3D model based upon the editing history of the 3D model. In operation, the collage engine processes an editing log to identify segments of the 3D model that include related vertices. For a given segment, the collage engine selects a viewpoint used by the end-user to edit the 3D model and a viewpoint used by the end-user to inspect the 3D model. The collage engine may then present the informative viewpoints to the end-user for inclusion in a collage of 2D renderings based upon the informative viewpoints. Generally, the viewpoints used while editing and inspecting the 3D model are of importance in the overall presentation of the 3D model. Therefore, collages of 2D renderings based upon the informative viewpoints can be generated effectively.

Abstract: A stroke parameterization engine within a rendering engine is configured to map a texture to the surface of a three-dimensional (3D) model along a stroke defined by an end-user of the rendering engine. The stroke parameterization engine converts the stroke to a polyline, then generates a geodesic trace by sliding a geodesic circle along the polyline and collecting points associated with the 3D model that fall within the geodesic circle. The stroke parameterization engine then parameterizes points associated with the polyline and the geodesic trace using UV coordinates associated with a texture map, thereby generating UV coordinates for each point within the polyline and geodesic trace. The stroke parameterization engine then projects the texture map onto the surface of the 3D model using the UV coordinates generated for the polyline and geodesic trace.

Abstract: One embodiment of the present invention sets forth a technique for mesh refinement. The technique involves receiving a mesh including a plurality of triangles. The technique further involves processing the mesh to generate a refined mesh by performing an edge flip operation on the mesh, performing an edge split operation on the mesh, and performing an edge collapse operation on the mesh.
