Methods

publicgeometricallyContains

• geometricallyContains(mesh: BimIfcMesh): boolean

• alpha

  Checks if all vertices of mesh are completely contained by the geometry.

  ---

  Parameters

  • mesh: BimIfcMesh

    Mesh of geometry to test.

  Returns boolean

publicgeometricallyContainsBoundingBox

• geometricallyContainsBoundingBox(bound: SimpleBoundingBox): boolean

• alpha

  Checks if bounds of object are inside of geometry.

  ---

  Parameters

  • bound: SimpleBoundingBox

    SimpleBoundingBox in world space.

  Returns boolean

publicgeometricallyIntersectingBoundingBox

• geometricallyIntersectingBoundingBox(bound: SimpleBoundingBox): boolean

• alpha

  Checks if bounds of object are inside of geometry.

  ---

  Parameters

  • bound: SimpleBoundingBox

    SimpleBoundingBox in world space.

  Returns boolean

publicgeometricallyIntersects

• geometricallyIntersects(mesh: BimIfcMesh): boolean

• alpha

  Checks if there is a vertex from the mesh on the inside and outside of the geometry.

  ---

  Parameters

  • mesh: BimIfcMesh

    Mesh of geometry to test.

  Returns boolean

publicgetIntersectionPoints

• getIntersectionPoints(screenCoordinateOrRay: Ray | Vector2, sceneOrOptions?: Scene): Intersection[]

• Finds all intersections of a Ray object and a this geometry. If a Vector2 object is provided, a screen-spaced Ray form pixel will be used for intersection test.

  ---

  Parameters

  • screenCoordinateOrRay: Ray | Vector2

  • optionalsceneOrOptions: Scene

  Returns Intersection[]

  Intersection info. Will be empty if no intersection was found.

publicintersect

• intersect(o: BimIfcMeshIntersectionOptions): Intersection[]

• Perform intersection testing on a BimIfcMesh.

  ---

  Parameters

  • o: BimIfcMeshIntersectionOptions

    Intersection options. See BimIfcMeshIntersectionOptions.

  Returns Intersection[]

  Intersection info. Will be empty if no intersection was found.
