GENERATING INFORMATIVE VIEWPOINTS BASED ON EDITING HISTORY

摘要

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.

1. A computer-implemented method for generating a collage of two-dimensional (2D) renderings that represent a three-dimensional (3D) model, the method comprising:
generating a first segment that includes a plurality of vertices associated with a first surface region of the 3D model; selecting a first edit record included in an edit log and corresponding to the first segment, wherein the first edit record is associated with a first edit operation applied to the plurality of vertices included in the first segment and with a first viewpoint implemented when rendering the 3D model during the first edit operation; and generating a first 2D rendering of the 3D model that represents the first segment relative to a perspective associated with the first viewpoint for inclusion in a collage of 2D renderings that represents the 3D model.
