Methods

Static Private _edgeAndNextAreCollinear

▸ _edgeAndNextAreCollinear(edge: MeshHalfEdge): boolean

Defined in src/util/Polygon3DFixing/FilterCollinearEdges.ts:74

Parameters:

Static Private _findNonCollinearStartEdge

▸ _findNonCollinearStartEdge(cycle: MeshHalfEdge[]): MeshHalfEdge | null

Defined in src/util/Polygon3DFixing/FilterCollinearEdges.ts:25

Parameters:

Name	Type

Static Private _skipCollinearEdges

▸ _skipCollinearEdges(cycle: MeshHalfEdge[], startEdge: MeshHalfEdge): MeshHalfEdge | null

Defined in src/util/Polygon3DFixing/FilterCollinearEdges.ts:48

Return null when the whole cycle degenerates.

Parameters:
