Class: SurfaceTessellation

This class manages the position of all the tessellation lines on one surface. The position and the rotation of the cutting lines are given by a PointOnEdgeAnchor, which is laying exactly on the edge of two cutlines.

Properties

Private anchor

• anchor: PointOnEdgeAnchor

Defined in src/modules/kyub.core.tessellate/src/SurfaceTessellation.ts:31

This uses two anchors to define it's position. As long as the PointOnEdgeAnchor stays valid, this is the source of truth. When it get's invalid, which can happen (f.e. with some AddBoxel-Operations), the surfaceAnchor and the signatureInformation are used, to find a new edge for the tessellation, for which then the PointOnEdgeAnchor is newly initialized.

▸ _setSurfaceAnchor(anchor: MeshSurfaceAnchor): void

Defined in src/modules/kyub.core.tessellate/src/SurfaceTessellation.ts:90

For serialization purpose

Parameters:

Name	Type	Description
anchor	MeshSurfaceAnchor	-

Returns: void

---

Private _updateSavedEdgeSignatures

▸ _updateSavedEdgeSignatures(): void

Returns: void

---

clone

▸ clone(): SurfaceTessellation

Defined in src/modules/kyub.core.tessellate/src/SurfaceTessellation.ts:47

Returns: SurfaceTessellation

---

cutPlate

▸ cutPlate(originalPlate: Plate): Promise‹void›

Defined in src/modules/kyub.core.tessellate/src/SurfaceTessellation.ts:135

This will split the plate accordingly to the SurfaceTessellation

Parameters:

Name	Type	Description
originalPlate	Plate	The plate supposed to get cut Todo: This might be better to move into a SurfaceTessellationRealizer, as the SurfaceTessellation should more be an Todo: abstract structure keeping only the data.

Return approximated lines we will later cut this surfaceTessellation with. Approximated means that we don't care about holes, or concave inlets in the shape. By convention, the start of the line will be the vector sorted after x, y, z.
