collectEdgesByDihedralAngle MethodStatic
Return manifold edge pairs whose dihedral angle is bounded by the given angle.
- The dihedral angle of a manifold edge is measured between the normals of its two adjacent faces.
- Boundary edges are not returned as they are not manifold.
collectEdgesByDihedralAngle(mesh: PolyfaceVisitor | Polyface, maxSmoothEdgeAngle?: Angle, sharpEdges: boolean = false): SortableEdgeCluster[]
| Parameter | Type | Description |
|---|---|---|
| mesh | PolyfaceVisitor | Polyface | existing polyface or visitor. |
| maxSmoothEdgeAngle | Angle | maximum dihedral angle of a smooth edge. If undefined, uses Geometry.smallAngleRadians. |
| sharpEdges | boolean | true to reverse the angle threshold test and return sharp edges; otherwise return smooth edges (default). |
Returns - SortableEdgeCluster[]

- polyface/PolyfaceQuery.ts Line 1862
