Methods

publicaabb

  • Calculates the min and max value in the coordinate system.

    Parameters

    • min: Vector3

      Minimum bounding vector3

    • max: Vector3

      Maximum bounding vector3

    • predicate: (o: BimIfcObject, recursionOptions: BimIfcObjectRecursionOptions) => unknown = DefaultBimIfcObjectForEachPredicate

      ?

    • clearTransformCache: boolean = true

      ?

    Returns void

publicapplyColor

  • applyColor(): void
  • @deprecated

    No longer does anything.

    Returns void

publicboundingInfo

  • Parameters

    Returns BoundingInfo

publiccomputeObjectBboxInWorldSpace

  • alpha

    Aggregates a bbox from current objects meshes. This does not include related children. This is alpha. Expect changes. Will probably be replaced by one of the other bounding info functions.

    @deprecated

    Use boundingInfo or aabb.

    Returns SimpleBoundingBox

publiccopyColorTo

  • copyColorTo(m: BimProductMesh, dst: Writeable<ArrayLike<number>>, dstOffset?: number): void

  • Parameters

    • m: BimProductMesh
    • dst: Writeable<ArrayLike<number>>
    • dstOffset: number = 0

    Returns void

publiccopyColorsTo

  • copyColorsTo(dst: Pick<Map<BimProductMesh, Writeable<ArrayLike<number>>>, set | get>): void

  • Parameters

    • dst: Pick<Map<BimProductMesh, Writeable<ArrayLike<number>>>, set | get>

    Returns void

publicdefaultColor

  • Parameters

    Returns boolean

publicentries

  • Gets a iterator for all Ifc products currently loaded.

    Returns IterableIterator<BimIfcObject>

publicforeach

publicgeometricallyIntersects

  • geometricallyIntersects(objects: BimIfcObject[], includeEnclosedObjects?: boolean, includeIntersectingObjects?: boolean): BimIfcObject[]

  • Checks intersections of an object (containing object) against an array of other objects.

    Parameters

    • objects: BimIfcObject[]

      Array of objects to test intersection against.

    • includeEnclosedObjects: boolean = true

      Default is true, it includes geometries completely geometrically on the inside, in the returned result.

    • includeIntersectingObjects: boolean = true

      Default is true, it includes geometries that intersects on border surface, in the returned result. If both enclosedObjects and intersectingObjects are false, the function will make a quick rough test based on bbox and return all objects intersecting and enclosing on bounding box level.

    Returns BimIfcObject[]

publicgetColorComponent

  • getColorComponent(m: BimProductMesh, colorComponent: RgbaComponent): number

  • Parameters

    Returns number

publicghostOutline

  • Makes the object give an ghosty outline when either SSAO or line outlines are enabled. It does this by making the object invisible but also flag it to still write to the depth buffer used by the lines and SSAO

    Parameters

    • enabled: boolean

      If true the object will be hidden but will also be set to still write to the depth buffer

    • optionalmeshes: BimProductMesh[]

      The specific meshes of the object to apply this method on

    Returns boolean

    A bool indicating if any of the objects meshes was changed as a result of this method call

publichighlight

  • Highlights the object

    Parameters

    • highlightIndex: IfcMaterialHighlightIndex = IfcMaterialHighlightIndex.One

      The highlight color index to use, setting it to zero means the mesh will not be highlighted

    • optionalmeshes: BimProductMesh[]

      The meshes to highlight

    Returns boolean

    a boolean indicating if the object was changed from the highlighting

publicisOnGpu

  • Parameters

    Returns boolean

publicmesh

publicmeshDescriptor

publicremove

  • remove(): void

  • Remove the IFC object and its children from the IFC hiearchy.

    Returns void

publicsetColor

  • setColor(color: ArrayLike<number>, meshes?: BimProductMesh[]): boolean

  • Parameters

    Returns boolean

publicsetColors

  • setColors(src: Iterable<[BimProductMesh, ArrayLike<number>]>): boolean

  • Parameters

    Returns boolean

publicstyle

publictransform

  • Parameters

    Returns Matrix

publicvertexData

publicstaticcreate

publicstaticcreateGeometryFrom

  • Creates a geometry consisting of all specified IFC objects (or specific meshes.).

    Parameters

    • items: (BimIfcObject | { ifcObject: BimIfcObject; meshes: BimProductMesh[] })[]

      All objects that will be combined. It is possible to optionally specify exactly which BimProductMesh that are to be used on each IFC object. If none is specified, then all meshes in the IFC objects are used. Geom. Items where isOnGpu === false will not be included in the final Geometry3d.

    Returns Geometry3d

    A Geometry3d instance that represents all geometry. Note that the geometry is in IFC space and not BabylonJS worldspace.

publicstaticcreateGeometryFromAsync

  • Creates a geometry consisting of all specified IFC objects (or specific meshes.).

    Parameters

    • items: (BimIfcObject | { ifcObject: BimIfcObject; meshes: BimProductMesh[] })[]

      All objects that will be combined. It is possible to specify multiple BimProductMesh to be used on each IFC object. If none are specified, then all meshes in the IFC objects are used. When isOnGpu === false, the geometry will automatically be loaded and included in the final Geometry3d.

    Returns Promise<Geometry3d>

    A Geometry3d instance that represents all geometry. Note that the geometry is in IFC space and not BabylonJS worldspace.
