Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:37

IPlateSplittingStrategy that determines how to split plates if needed

Methods

Private _alignCrossJoints

▸ _alignCrossJoints(): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:369

Aligns cross joints to make them easier to assemble, i.e. makes that all plates going along one side have the slit on the top, and all plates going the along the other side have the slit on the bottom

Returns: void

---

Private _createCrossJoint

▸ _createCrossJoint(plateA: Plate, plateB: Plate, start: Vector3, end: Vector3): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:106

Parameters:

Name	Type
plateA	Plate
plateB	Plate
start	Vector3
end	Vector3

Returns: void

---

Private _createFingerJoint

▸ _createFingerJoint(jointPosition: IJointPosition): void

Parameters:

Name	Type

Private _createMissingJoints

▸ _createMissingJoints(): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:72

Returns: void

---

Private _createPairOfAlternatingTeeJoints

▸ _createPairOfAlternatingTeeJoints(plateA: Plate, plateB: Plate, continuousPlate: Plate): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:515

Create a pair of TeeJoints for two colliding reinforcement plates. The TeeJoints need to be created synchronously because a flag (isStartingAtCollision) needs to be set here. Depending on the value of isStartingAtCollision the TeeJointRenderer creates alternating TeeJoints.

Parameters:

Name	Type	Description
plateA	Plate	One part of the split plate
plateB	Plate	The other part of the split plate
continuousPlate	Plate	The continuous plate

Returns: void

---

Private _createTeeJoint

▸ _createTeeJoint(section: OutlineSection, plate: Plate): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:122

Parameters:

Name	Type
section	OutlineSection
plate	Plate

Returns: void

---

Private _fixPlateCollisions

▸ _fixPlateCollisions(preferredMethod: any): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:277

Merging plates may create plates that overlap, but are not joined. This method inspects the assembly, splits plates and creates joints in order to make the assembly physically buildable.

Parameters:

Name	Type	Description
preferredMethod	any	preferred method how to resolve collisions, either 'TeeJoint' or 'CrossJoint'

Returns: void

---

Private _getIntersectingPlates

▸ _getIntersectingPlates(assembly: Assembly): Array‹[Plate, Plate]›

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:566

an list of two physically intersecting plates each. Plates joined with each other are ignored. Plates where one plate touches the other

Parameters:

Name	Type
assembly	Assembly

Returns: Array‹[Plate, Plate]›

---

Private _groupPlatesByNormal

▸ _groupPlatesByNormal(plates: Plate[]): Map‹Vector3, Plate[]›

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:412

Parameters:

Name	Type	Description
plates	Plate[]	that need to be grouped

Returns: Map‹Vector3, Plate[]›

map of normal vector to the plates having this or the negated equivalent normal

---

Private _insertOutlinePointsIfRequired

▸ _insertOutlinePointsIfRequired(): void

Defined in src/model/data/Component/plateMerging/PlateMergingComponent.ts:164

This function makes sure that for every start and end of a joint under creation there is a point in the outline. After that, the outline is subdivided such that joint creation becomes as simple as linking the right sections.

                                  |←     sectionA    →|
        outline of plateA    -----●-------------------●----------
                                    |← desired joint →|
        outline of plateB    ---●--------------●-----------------
                                |←  sectionB  →|

                                          ↓

        outline of plateA    -----●-○-----------------●----------
                                    |← desired joint →|
        outline of plateB    ---●---○----------●------○----------
                                     ↖ inserted point

The Joint Model can only handle Joints between either a pair of OutlineSections (FingerJoint) or an OutlineSection and a Plate (TeeJoint) or a pair of Plates (CrossJoint). For the first two cases we might need to split existing OutlineSections. After we ensured that all necessary OutlinePoints are created, we create the Joints between them.
