Class PackedMesh<ModelType>

constructor

• new PackedMesh<ModelType extends Model<ModelType>>(
      model: ModelType,
      materials: readonly CanonicalMaterial[],
      primitives: readonly [GeometryObject, undefined | number][],
      triangleElementMaps: readonly TriangleElementMap[],
      elementPrimitiveIndex: ReadonlyMap<number, number[]>,
  ): PackedMesh<ModelType>

• Construct a packed mesh.

  Type Parameters

  • ModelType extends Model<ModelType>

  Parameters

  • model: ModelType

    The model this mesh came from.
  • materials: readonly CanonicalMaterial[]

    The materials array for the packed mesh (referenced by index by primitives)
  • primitives: readonly [GeometryObject, undefined | number][]

    The primitives for this mesh (the mesh fragments by material), with the material index being the second item of the tuple.
  • triangleElementMaps: readonly TriangleElementMap[]

    Triangle element maps (one per primitive, in the same order, to map elements to primitives)
  • elementPrimitiveIndex: ReadonlyMap<number, number[]>

    Element primitive index, maps element local ids to the correct primitive.

  Returns PackedMesh<ModelType>

Readonlymaterials

Readonlymodel

Readonlyprimitives

ReadonlytriangleElementMaps

triangles

• triangles(
      cursor: IIndexSetCursor,
  ): IterableIterator<[number, number, ReadonlyUint32Array]>

• Get triangles from a cursor.

  Parameters

  • cursor: IIndexSetCursor

    The cursor to extract triangles for

  Returns IterableIterator<[number, number, ReadonlyUint32Array]>

  Yields

  Returns a tuple containing the local ID of the element, the primitive index, and the triangles.

  Note - there may be multiple batches of triangles from the same element, because the triangles maybe in different primitives.
