Constructors

constructor

new FrustumMesh(engine: WonderlandEngine, polyline: vec2[], apex: vec3, height: number, options?: FrustumOptions): FrustumMesh
Make a new frustum.
Parameters
- engine: WonderlandEngine
  
  The Wonderland Engine instance to use this mesh for
- polyline: vec2[]
  
  The polyline for the base.
- apex: vec3
  
  The apex point of the frustum.
- height: number
  
  The height of the frustum. The height is expected to not exceed the apex.
- Optional options: FrustumOptions
  
  Optional arguments for the frustum generation.
Returns FrustumMesh
Overrides BasePrismoidPyramidMesh.constructor
- Defined in client/FrustumMesh.ts:35

Properties

autoDispose

autoDispose: boolean = false

If this flag is set, then dispose will be called after a CSG operation is done. It's recommended to call mark instead of setting this manually, since the method is chainable.

`Protected` premadeMergeMap

premadeMergeMap: null | MergeMap = null

A merge map that defines how to create a manifold from the submeshes.

`Protected` submeshes

submeshes: Submesh[] = []

The list of submeshes to assign to this group.

Accessors

mergeMap

get mergeMap(): MergeMap
Get the merge map of this MeshGroup. If the MeshGroup has no merge map yet, then a merge map will be automatically generated and cached. Note that this process can throw.

Returns MergeMap
Inherited from BasePrismoidPyramidMesh.mergeMap
- Defined in client/MeshGroup.ts:172

submeshCount

get submeshCount(): number
Get the number of submeshes inside this MeshGroup.

Returns number
Inherited from BasePrismoidPyramidMesh.submeshCount
- Defined in client/MeshGroup.ts:193

Methods

dispose

dispose(): void
Destroy the Wonderland Engine meshes stored in this object. Note that if the submeshes are reused elsewhere, then this will destroy those too.

Returns void
Inherited from BasePrismoidPyramidMesh.dispose
- Defined in client/MeshGroup.ts:233

encode

encode(materials: Material[], transferables: Transferable[]): EncodedMeshGroup
Encode into a format that is passable to the Manifold worker, along with a numeric mapping for materials.
Parameters
- materials: Material[]
- transferables: Transferable[]
Returns EncodedMeshGroup
Inherited from BasePrismoidPyramidMesh.encode
- Defined in client/MeshGroup.ts:340

getSubmesh

getSubmesh(submeshIdx: number): Submesh
Get the submeshes at a specific submesh index.

Returns
A pair containing a WL.Mesh instance and a WL.Material instance.
Parameters
- submeshIdx: number
  
  The index of the wanted submesh.
Returns Submesh
Inherited from BasePrismoidPyramidMesh.getSubmesh
- Defined in client/MeshGroup.ts:203

getSubmeshes

getSubmeshes(): Submesh[]
Get the submeshes inside this MeshGroup.

Returns
A list of submeshes, where each submesh is a pair containing a WL.Mesh instance and a WL.Material instance.

Returns Submesh[]
Inherited from BasePrismoidPyramidMesh.getSubmeshes
- Defined in client/MeshGroup.ts:218

mark

mark(): FrustumMesh
Sets autoDispose to true (marks as auto-disposable). Chainable method.

Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.mark
- Defined in client/MeshGroup.ts:246

rotate

rotate(rotation: quat): FrustumMesh
Rotate all submeshes and the manifold by a given quaternion. Chainable method.
Parameters
- rotation: quat
Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.rotate
- Defined in client/MeshGroup.ts:328

scale

scale(factor: vec3): FrustumMesh
Scale all submeshes and the manifold by a given per-axis factor. Chainable method.
Parameters
- factor: vec3
Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.scale
- Defined in client/MeshGroup.ts:310

transform

transform(matrix: mat4, normalMatrix?: mat3): FrustumMesh
Transform all submeshes and the manifold by a given matrix and normal matrix. Chainable method.
Parameters
- matrix: mat4
- Optional normalMatrix: mat3
Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.transform
- Defined in client/MeshGroup.ts:255

translate

translate(translation: vec3): FrustumMesh
Translate all submeshes and the manifold by a given translation vector. Chainable method.
Parameters
- translation: vec3
Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.translate
- Defined in client/MeshGroup.ts:301

uniformScale

uniformScale(factor: number): FrustumMesh
Scale all submeshes and the manifold by a single factor. Chainable method.
Parameters
- factor: number
Returns FrustumMesh
Inherited from BasePrismoidPyramidMesh.uniformScale
- Defined in client/MeshGroup.ts:319

`Static` fromEncodedMeshGroup

fromEncodedMeshGroup(engine: WonderlandEngine, encodedMeshGroup: EncodedMeshGroup, materials: Material[]): MeshGroup
Create a new MeshGroup from an EncodedMeshGroup.
Parameters
- engine: WonderlandEngine
- encodedMeshGroup: EncodedMeshGroup
- materials: Material[]
Returns MeshGroup
Inherited from BasePrismoidPyramidMesh.fromEncodedMeshGroup
- Defined in client/MeshGroup.ts:82

`Static` fromWLEMesh

fromWLEMesh(mesh: Mesh, material?: null | Material): MeshGroup
Create a new MeshGroup from a WL.Mesh.

WARNING: The submeshes array and the manifold mesh will have their ownership tranferred to this object. If you modify them later, they will be modified here as well, possibly corrupting the mesh. To avoid issues with this, do a deep clone of the inputs
Parameters
- mesh: Mesh
  
  A WL.Mesh instance.
- material: null | Material = null
  
  A WL.Material instance. Null by default.
Returns MeshGroup
Inherited from BasePrismoidPyramidMesh.fromWLEMesh
- Defined in client/MeshGroup.ts:77

`Static` makeEmpty

makeEmpty(): MeshGroup
Create a new empty MeshGroup. Useless on its own, only ever appears as a fallback for CSG operations with no result.

Returns MeshGroup
Inherited from BasePrismoidPyramidMesh.makeEmpty
- Defined in client/MeshGroup.ts:160
