announceBoundaryEdges MethodStatic
Test if the facets in source occur in perfectly mated pairs, as is required for a closed manifold volume.
If not, extract the boundary edges as lines.
announceBoundaryEdges(source: undefined | Polyface | PolyfaceVisitor, announceEdge: (pointA: Point3d, pointB: Point3d, indexA: number, indexB: number, facetIndex: number) => void, includeTypical: boolean = true, includeMismatch: boolean = true, includeNull: boolean = true): void
| Parameter | Type | Description |
|---|---|---|
| source | undefined | Polyface | PolyfaceVisitor | polyface or visitor |
| announceEdge | (pointA: Point3d, pointB: Point3d, indexA: number, indexB: number, facetIndex: number) => void | function to be called with each boundary edge. The announcement is start and end points, start and end indices, and facet index. |
| includeTypical | boolean | true to announce typical boundary edges with a single incident facet |
| includeMismatch | boolean | true to announce edges with more than 2 incident facets |
| includeNull | boolean | true to announce edges with identical start and end vertex indices. |
Returns - void
