Detailed Description

Assemble independently constructed trimmed faces into shared OpenNURBS topology. These routines do not standardize or compact a B-Rep.

Function Documentation

brep_curves_coincident()

bool brep_curves_coincident ( const ON_Curve &  first, const ON_Curve &  second, double  tolerance, bool *  reversed = NULL  )

extern

Bound whether two curves trace the same locus within tolerance. Returns false when refinement cannot establish coincidence within its work limit. Point samples alone never establish a match.

brep_stitch_naked_edges()

int brep_stitch_naked_edges ( ON_Brep &  brep, double  tolerance, brep_assembly_result *  result = NULL  )

extern

Merge unambiguous pairs of coincident naked edges in place.

Each retained edge acquires the trims from its duplicate. Face pcurves are not changed. Returns the number of merged edges, or -1 on an OpenNURBS topology error. Ambiguous matches are deliberately left naked.

brep_set_edge_endpoint_tolerances()

bool brep_set_edge_endpoint_tolerances ( ON_Brep &  brep, double  minimum_tolerance  )

extern

Derive edge tolerances required by authored vertex and trim endpoints. Geometry is not changed; existing larger tolerances are preserved.

brep_orient_faces()

bool brep_orient_faces ( ON_Brep &  brep )

extern

Make face orientations consistent in a closed two-manifold B-Rep.

brep_assemble()

bool brep_assemble ( ON_Brep &  brep, double  tolerance, brep_assembly_result *  result = NULL  )

extern

Stitch, orient, derive tolerances and flags, and validate an assembled B-Rep. The return value reports whether the resulting B-Rep is valid; solidity and incomplete topology are reported separately in result.
