Methods

modify

modify(geometry: BufferGeometry): BufferGeometry

Inherited from SubdivisionModifier.modify
- Defined in @here/harp-geometry/lib/SubdivisionModifier.ts:33
Subdivides the faces of the given [[THREE.BufferGeometry]].

This method modifies (in-place) the vertices and the faces of the geometry. Please note that only the vertex position and their UV coordinates are subdivided. Normals, vertex colors and other attributes are left unmodified.

Parameters
- geometry: BufferGeometry
  
  The [[THREE.BufferGeometry]] to subdivide.
Returns BufferGeometry

Protected shouldSplitTriangle

shouldSplitTriangle(a: Vector3, b: Vector3, c: Vector3): number | undefined

Overrides SubdivisionModifier.shouldSplitTriangle
- Defined in @here/harp-geometry/lib/EdgeLengthGeometrySubdivisionModifier.ts:106
override

Parameters
- a: Vector3
- b: Vector3
- c: Vector3
Returns number | undefined
