Class: CellFactory

Builds CellMembranes for an assembly and provides methods for updating its mesh. Current building-algorithm only works on axis-aligned cuboids (assumptions are marked in the code)

Properties

Private cellSize

• cellSize: Vector2

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:93

---

Private cells

• cells: CellMembrane[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:94

---

Private mesh

• mesh: Mesh

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:92

Methods

Private _buildFromPlane

▸ _buildFromPlane(plane: Plane): CellMembrane[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:298

Find all intersecting cycles and convert each to a cell

Parameters:

Name	Type
plane	Plane

Returns: CellMembrane[]

---

Private _buildGrid

▸ _buildGrid(): Plane[][]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:254

Lays a grid with a given cell size over the mesh. The longest side of the assemblies aabb will get the longer cell size, everything else gets the shorter cell size

This is not an optimal placement (but it's fast)

Returns: Plane[][]

the planes where cuts of the grid are per axis

---

Private _buildMiddleOutline

▸ _buildMiddleOutline(membrane: CellMembrane): Outline

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:218

Parameters:

Name	Type
membrane	CellMembrane

Returns: Outline

---

Private _buildWithExiting

▸ _buildWithExiting(): CellMembrane[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:114

Returns: CellMembrane[]

---

Private _calculateNeededMembrane

▸ _calculateNeededMembrane(surface: MeshSurface, membranes: CellMembrane[]): CellMembrane

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:144

A surface needs another membrane if for any section the distance of the first or last membrane along the section to the start or end of the section is greater than the material size

Limitations: - Only works with rectangular surfaces - Only checks the minimal dimensions of the material size and not both dimensions

Parameters:

Name	Type
surface	MeshSurface
membranes	CellMembrane[]

Returns: CellMembrane

---

Private _getAnchorFromPosition

▸ _getAnchorFromPosition(position: Vector3, plane: Plane): PointOnEdgeAnchor

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:314

Parameters:

Name	Type
position	Vector3
plane	Plane

Returns: PointOnEdgeAnchor

---

Private _getTouchingSurfaces

▸ _getTouchingSurfaces(middle: Outline): MeshSurfaceAnchor[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:232

Find Plates which touch the membrane and return the Anchor of their MeshSurface

Parameters:

Name	Type
middle	Outline

Returns: MeshSurfaceAnchor[]

---

build

▸ build(mesh: Mesh, materialSize: Vector2, existingCells: CellMembrane[]): CellMembrane[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:99

Builds new membranes on a cuboid mesh with or without existing membranes

Parameters:

Name	Type	Default
mesh	Mesh	-
materialSize	Vector2	-
existingCells	CellMembrane[]	[]

Returns: CellMembrane[]

---

Static Private _buildMiddleOutlines

▸ _buildMiddleOutlines(plane: Plane, assembly: Assembly): Outline[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:65

Searches for a Cycles in the intersections of the cells plane and the plates to intersect.

Parameters:

Name	Type
plane	Plane
assembly	Assembly

Returns: Outline[]

---

Static Private _createSurfaceDescriptor

▸ _createSurfaceDescriptor(outline: Outline): SingleSurfaceDescriptor

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:69

Parameters:

Name	Type
outline	Outline

Returns: SingleSurfaceDescriptor

---

Static Private _flipNormalIfNeeded

▸ _flipNormalIfNeeded(normal: Vector3): Vector3

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:85

Flips the normal so it points into positive xyz-space. This only works on axis aligned cuboids

Parameters:

Name	Type
normal	Vector3

Returns: Vector3

---

Static findUnusedMembranes

▸ findUnusedMembranes(cells: CellMembrane[], mesh: Mesh): CellMembrane[]

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:50

Return membranes that are not intersecting all their surrounding surfaces

Parameters:

Name	Type
cells	CellMembrane[]
mesh	Mesh

Returns: CellMembrane[]

---

Static updateMembraneSizeAfterPushPull

▸ updateMembraneSizeAfterPushPull(membrane: CellMembrane, otherMesh: Mesh): void

Defined in src/modules/kyub.core.cell/src/CellFactory.ts:32

If push-pull widens the box orthogonal to a membrane, the membrane needs to be made wider as well. This is done by modifying the mesh (SingleSurface) of the membrane

Parameters:

Name	Type	Description
membrane	CellMembrane	The membrane to update
otherMesh	Mesh	The mesh that got push-pulled

Returns: void
