Abstract: Systems and methods of updating graphical objects are disclosed. The methods and systems receive polygonal data which described points on an object. A user indicates a length, and retopologized data for a region is automatically generated based on the length such that the retopologized data has fewer geometries than the received polygonal data in the region.

Abstract: Methods of producing an electronic geometric model, and systems which perform the methods are disclosed. In some embodiments, the method includes accessing electronic data, the data including polygonal data defining a reference object and a mesh of polygonal data points, the mesh including a plurality of edges. Such methods also include selecting an edge of the mesh, and in response to an indication from a user determining locations for additional data points, where the locations are adjacent to the selected edge and contact portions of the reference object. Such methods also include inserting the additional data points into the accessed data at the determined locations, and subdividing the accessed data having the additional data points with a subdivision algorithm, whereby subdivided data is generated. Such methods also include generating the geometric model based on the subdivided data, and storing the geometric model in a computer readable data storage.

Abstract: Systems and methods of updating graphical objects are disclosed. The methods and systems received polygonal data which describe discrete points on an object. A control mesh and a smoothed version of the control mesh are simultaneously displayed. When the control mesh is edited, the smoothed version is automatically updated by smoothing only a portion of the edited control mesh to generate a smoothed section, and replacing a portion of the smoothed version with at least a selected portion of the smoothed section.

Abstract: Methods and computer systems for generating and polygonal data are disclosed. The methods and systems receive polygonal data which describe discrete points on an object. The methods and systems algorithmically add vertices and edges prior to algorithmically smoothing and conforming the polygonal data in order to produce desired features, such as fillets, in the smoothed data.
