Constructors

publicconstructor

  • Constructor.

    Parameters

    • canvas: HTMLCanvasElement

      Canvas element where 3D content will be rendered.

    • _apiClient: TwinfinityApiClient
    • optionalbimApiOptions: Object

    Returns BimApi

Properties

publicreadonlycamera

camera: BimCamera

Camera is an instance of BimCamera and used for manipulating the 3D camera view of the BIM viewer.

publicreadonlyviewer

viewer: TwinfinityViewer

Exposes viewer internals. Use this to access BabylonJS API. Disclaimer! Accessing BabylonJS internals is considered advanced usage and you are effectively bypassing BimCoreApi (and subclasses). We cannot make guarantees that:

  • BabylonJS APIs will remain backwards compatible. Therefore, your application may break when BabylonJS is updated to a new version.
  • Babylonjs data that BimCoreApi creates, such as scene hierarchy, lights, camera etc., will remain backwards compatible between versions. Relying on this may break your application.
  • Your modifications to BabylonJS data (such as scene hierarchy, lights, cameras etc.) will not be changed by code in this package.
  • Other bugs will not occur as a result of direct usage of BabylonJS APIs. https://doc.babylonjs.com/api/classes/babylon.scene
@example
api.viewer.scene.ambientColor = new Color3(1, 0, 0);

publicstaticrunRenderLoop
beta

runRenderLoop: RunRenderLoopHandler = ...

Extension point for applications that need to run the renderloop outside their own change handling (AngularJs is one such example). Assignment should be done before creation of a BimCoreApi instance.

@example

Example for Angular JS

 const bimApi: BimApi;
 BimCoreApi.runRenderLoop = this.ngZone.runOutSideAngular;
@param

Renderloop function will be provided by the viewer. Simply call it in your provided function

        }
    });

    Parameters

    Returns void

publicgetIntersections

  • Intersects all visible BIM objects using ray from origin towards direction

    @example
    // GetIntersections makes a hit test on all visible BIM objects, from origin in direction and return first object intersection.
    const intersections = this.api.getIntersections([0, 0, 0], [1, 1, 1]);
    @example
    // GetIntersections makes a hit test on a subset of  BIM objects, from origin in direction and return first object intersection.
    const intersections = this.api.withSelection(myVisibleObjects, objects => this.api.getIntersections([0, 0, 0], [1, 1, 1]);
    @example
    // GetIntersections makes a hit test on a subset of visible BIM objects, from origin in direction and return first object intersection.
    const intersections = this.api.getIntersections([0, 0, 0], [1, 1, 1], myObjects);

    Parameters

    • direction: Vector3
    • objects: BimIfcObject[] = []

    Returns undefined | Intersection[]

    Intersection[] | undefined

publicinfo

  • General Twinfinity information such as customer portal name, Twinfinity API version etc.

    Returns TwinfinityInfo

publicloadPropertySets

  • loadPropertySets(): Promise<void>

  • Loads all BIM property sets for all loaded files.

    @deprecated

    Use ifc.loadPropertySets instead.

    Returns Promise<void>

publicon

  • Sets a handler to event of given type

    @deprecated

    Use onPointerObservable instead.

    Parameters

    • type: click

      Type of event. For now only “click” is supported

    • clickEventHandler: ClickEventHandler

    Returns void

publicproducts

  • Create a iterator that can be used to iterate over all BimIfcObject‘s. Same as foreach but with a iterator instead.

    @example
    for(const o of api.products()) {
        if (o.hasGeometry && o.class.id !== "IfcFlowSegment") {
            console.log(o.gid);

publicsetBackgroundColor

  • setBackgroundColor(color: Color3 | Color): void

  • Sets background color in viewer

    @example
    api.setBackgroundColor([0.95, 0.95, 0.95]);

    Parameters

    • color: Color3 | Color

      RGB in range 0-1

    Returns void

publicsetContainer

publicsetHighlightColor

  • Sets highlight color in viewer

    Parameters

    • color: Color3

      RGB in range 0-1

    • highlightIndex: IfcMaterialHighlightIndex = IfcMaterialHighlightIndex.One

      The highlight index tgo change, it’s restricted to One, Two and Three because it makes no sense to change the color of the Empty index (since it’s only there to denote that a productMesh has no highlight). The highlight index defaults to One

    Returns void

publicwithVisibleBimObjects

  • Makes it possible to perform API operations, that operate on the set of visible BIM objects, on a smaller set of (still visible) BIM objects

    @example
    // GetIntersections makes a hit test on a subset of visible BIM objects, from origin in direction and return first object intersection.
