aabb

• get aabb(): { max: Vector3; min: Vector3 }

  The axis-aligned bounding box of the geometry.

  Returns { max: Vector3; min: Vector3 }

center

• get center(): Vector3

  The center of the geometry's axis-aligned bounding box in IFC space.

  Returns Vector3

cullingDistance

• get cullingDistance(): number

  The distance at which the geometry should be culled.

  Returns number

cullOnCameraMove

• get cullOnCameraMove(): boolean

  Specifies whether to cull the geometry when the camera moves.

  Returns boolean

indices

• get indices(): GeometryIndiceArray

  Indices. Describes triangles by referencing items in positions.

  Returns GeometryIndiceArray

positions

• get positions(): Float32Array<ArrayBufferLike>

  Positions (x,y,z).

  Returns Float32Array<ArrayBufferLike>

uvs

• get uvs(): Float32Array<ArrayBufferLike>

  Uvs (u,v)

  Returns Float32Array<ArrayBufferLike>

applyToGeometry

• applyToGeometry(babylonGeometry: Geometry, engine: Engine): void

  Applies the geometry data this instances represents (positions, uvs, indices, aabb and optionally normals.) to the specified Geometry. Notice that the geometry is in IFC space. If geometry is assing to a Mesh one can use coordinateSystems.toBabylonTransform as the mesh pretransform matrix. This will ensure that mesh behaves as if it is in BabylonJS worldspace.

  Parameters

  • babylonGeometry: Geometry

    Geometry to receive geometry data.
  • engine: Engine

  Returns void

applyToMesh

• applyToMesh(mesh: Mesh, engine: Engine): void

  Applies the geometry data this instances represents (positions, uvs, indices, aabb and optionally normals.) to the specified Mesh.

  Parameters

  • mesh: Mesh

    Mesh to receive geometry data.
  • engine: Engine

  Returns void

copyNormalsTo

• copyNormalsTo<T extends Writeable<ArrayLike<number>>>(dst: T): T

  Copies normals to existing array.

  Type Parameters

  • T extends Writeable<ArrayLike<number>>

  Parameters

  • dst: T

  Returns T

merge

• merge(): Geometry3d

  Returns Geometry3d

toHandle

• toHandle(): Geometry3dHandle

  Handle for this geometry. Can be used to unload the geometry from the GPU.

  Returns Geometry3dHandle
