Constructors

publicconstructor

• new BimTransformsRepository(_loaderElement: IBimIfcLoaderElement): BimTransformsRepository

• Constructs a new instance of the BimTransformsRepository class.

  ---

  Parameters

  • _loaderElement: IBimIfcLoaderElement

    The IBimIfcLoaderElement used for loading IFC data.

  Returns BimTransformsRepository

Methods

publicclear

• clear(): void

• Clears the transforms repository by removing all cached transforms.

  ---

  Returns void

publicconvertBimTransformToMatrixToRef

• convertBimTransformToMatrixToRef(wt: BimTransform, outMatrix: Matrix): Matrix

• Converts a BimTransform to a Matrix and assigns the result to the provided outMatrix.

  ---

  Parameters

  • wt: BimTransform

    The BimTransform to convert.

  • outMatrix: Matrix

    The Matrix to assign the converted result to.

  Returns Matrix

  The converted Matrix. Same as outMatrix.

publicgetMatrix

• getMatrix(m: BimProductMesh): Matrix

• Retrieves the matrix associated with the given BimProductMesh. If the matrix is already cached, it is returned directly. Otherwise, the matrix is calculated, cached, and returned.

  ---

  Parameters

  • m: BimProductMesh

    The BimProductMesh for which to retrieve the matrix.

  Returns Matrix

  The matrix associated with the given BimProductMesh.

publicgetTransform

• getTransform(m: BimProductMesh): FastTransform

• Retrieves the FastTransform for the given BimProductMesh. If the FastTransform is already cached, it is returned directly. Otherwise, a new FastTransform is created, cached, and returned.

  ---

  Parameters

  • m: BimProductMesh

    The BimProductMesh for which to retrieve the FastTransform.

  Returns FastTransform

  The FastTransform for the given BimProductMesh.
