announceSilhouetteEdges MethodStatic
Invoke the callback on each manifold edge whose adjacent facet normals form vectorToEye dot products with opposite sign.
- The callback is not called on boundary edges.
announceSilhouetteEdges(source: Polyface | PolyfaceVisitor, announce: (pointA: Point3d, pointB: Point3d, vertexIndexA: number, vertexIndexB: number, facetIndex: number) => void, vectorToEye: Vector3d, sideAngle: Angle = ...): void
| Parameter | Type | Description |
|---|---|---|
| source | Polyface | PolyfaceVisitor | facets |
| announce | (pointA: Point3d, pointB: Point3d, vertexIndexA: number, vertexIndexB: number, facetIndex: number) => void | callback function invoked on manifold silhouette edges |
| vectorToEye | Vector3d | normal of plane in which to compute silhouette edges |
| sideAngle | Angle | angular tolerance for perpendicularity test |
Returns - void
