Three dimensional modeling accuracy analyzing medium for use during processing of three dimensional scanning data, has instructions for presenting measure of loss of accuracy, which is to be assigned to selected operation, to user

摘要

The medium has a set of instructions for providing a collection available of three dimensional (3D) scanning data (4) forming a model (12) e.g. lattice model or scatter-plot model, which represents a form of a three-dimensional object. A computer aided design (CAD) system is provided to remodel a CAD subfield, which is formed by the 3D scanning data. An operation is selected to manipulate a part of the 3D scanning data or a part of the CAD subfield. A measure of loss of accuracy, which is to be assigned to the selected operation, is determined and is presented to the user. Independent claims are also included for the following: (1) a method for analyzing a three dimensional modeling accuracy during processing of three dimensional scanning data (2) a system for analyzing three dimensional modeling accuracy during processing of three dimensional scanning data.
