readonlyifcName

ifcName: string

The name of the IFC file this instance represents.

readonlyifcProductsWithGeometryCount

ifcProductsWithGeometryCount: number

The total number of BimProductMesh instances in the IFC file this instance represents. Same as meshCount.

readonlyifcUrl

ifcUrl: URL

The url where the contents of the IFC file can be retrieved from.

readonlyindex

readonlyloader

loader: BimIfcLoaderElementParent

The loader this instance belongs to.

readonlymaterials

materials: Materials

Reference to a Materials instance.

readonlymeshCount

meshCount: number

The total number of BimProductMesh instances in the IFC file this instance represents. Same as ifcProductsWithGeometryCount.

readonlynumberOfIndices

numberOfIndices: number

The total number of indices contained in all instances of BimProductMesh in this IFC file.

optionalreadonlytransform

transform?: Matrix

An optional transform for the IFC file. This transform will be applied to all IFC product geometries

readonlytransformsRepository

transformsRepository: BimTransformsRepository

Reference to the transform repository this instance uses when transforming IFC product geometries.

readonlytypeObjectRepository

typeObjectRepository: BimTypeObjectRepository

Reference to the type object repository this instance uses for type properties.

Methods

ensureVertexDataLoaded

  • ensureVertexDataLoaded(): Promise<boolean>

  • Ensures that the vertex data is loaded.

    Returns Promise<boolean>

    A promise that resolves to a boolean. See it as a signal. I will be true if the call actualy loaded the data. Otherwhise it will be false (data loading is either in progress or has completed).

getVertexData

loadPropertySets

  • loadPropertySets(): Promise<boolean>

  • Loads the property sets and assigns them to the IFC products contained within this instance.

    Returns Promise<boolean>

    A promise that resolves to a boolean indicating whether the property set was loade

writeVertexData

  • writeVertexData(ifcProductMesh: BimProductMesh, transform: FastTransform, destination: GeometryArrays, offset: GeometryArrayOffset, aabb: { max: Vector3; min: Vector3 }, options: { includeNormals?: boolean }): void

  • Writes the vertex data to the specified destination.

    Parameters

    • ifcProductMesh: BimProductMesh

      The IFC product mesh.

    • transform: FastTransform

      The transformation matrix.

    • destination: GeometryArrays

      The destination geometry arrays.

    • offset: GeometryArrayOffset

      The offset in the geometry arrays.

    • aabb: { max: Vector3; min: Vector3 }

      The axis-aligned bounding box.

    • options: { includeNormals?: boolean }

    Returns void
