Abstract
A computer-implemented solid modeling system that detects incorrect orientations of lofted solids involving non-degenerate, degenerate, closed cases, and then ensures that the face normals of the lofted solids are correctly oriented, so that they are pointing outwards with respect to the material side of each face.
Claims36
A computer-implemented graphics system, comprising:
- (a) a computer;
- and
- (b) a feature-based modeler, executed by the computer, for processing a representation of a three-dimensional (3D) model that includes at least one lofted solid, wherein the feature-based modeler detects an incorrect orientation of the lofted solid in the 3D model and ensures that one or more face normals of the lofted solid are correctly oriented.
A computer-implemented method of processing a three-dimensional (3D) model that includes at least one lofted solid, comprising:
- (a) detecting an incorrect orientation of the lofted solid in the 3D model;
- and
- (b) ensuring that one or more face normals of the lofted solid are correctly oriented in response to the detected incorrect orientation.
An article of manufacture embodying logic for performing a computer-implemented method of processing a three-dimensional (3D) model that includes at least one lofted solid, the method comprising:
- (a) detecting an incorrect orientation of the lofted solid in the 3D model;
- and
- (b) ensuring that one or more face normals of the lofted solid are correctly oriented in response to the detected incorrect orientation.
