Function

Name Description
GraphicDescriptionBuilder.create Create a GraphicDescriptionBuilder using the specified options.

Defined in

GraphicDescriptionBuilder Interface

An equivalent of a GraphicBuilder that is designed for use on a Worker. Unlike GraphicBuilder.finish, which produces a RenderGraphic, GraphicDescriptionBuilder.finish produces a GraphicDescription. The GraphicDescription can be returned from the Worker to the main thread, where createGraphicFromDescription can be used to quickly convert it to a RenderGraphic. Produce graphics using GraphicDescriptionBuilder on a Worker instead of using GraphicBuilder when you have graphics that may take a non-trivial amount of time to create, to avoid blocking the main JavaScript event loop.

@see GraphicDescriptionBuilder.create to instantiate this type.

Methods

Name Description
finish(): GraphicDescription Processes the accumulated symbology and geometry to produce a description of a renderable graphic.

Inherited properties

Name Type Inherited from Description
pickable Readonly Inherited Readonly<PickableGraphicOptions> | undefined GraphicAssembler If the graphic is to be interactive, specifies its Id and other options.
placement Readonly Inherited Transform GraphicAssembler The local-to-world transform in which the builder's geometry is to be defined.
preserveOrder Readonly Inherited boolean GraphicAssembler If true, the order in which geometry is added to the builder is preserved.
type Readonly Inherited GraphicType GraphicAssembler The type of graphic to be produced.
wantEdges Readonly Inherited boolean GraphicAssembler If true, edges are generated for surfaces, to be drawn if edge display is enabled for the view in which the graphic is drawn.
wantNormals Readonly Inherited boolean GraphicAssembler If true, normal vectors will be generated for surfaces, allowing 3d geometry to receive lighting and reduce z-fighting.
isOverlay Accessor Inherited ReadOnly boolean GraphicAssembler True if the builder produces a graphic of WorldOverlay or ViewOerlay.
isSceneGraphic Accessor Inherited ReadOnly boolean GraphicAssembler True if the builder produces a graphic of GraphicType.Scene.
isViewBackground Accessor Inherited ReadOnly boolean GraphicAssembler True if the builder produces a graphic of ViewBackground.
isViewCoordinates Accessor Inherited ReadOnly boolean GraphicAssembler Whether the builder's geometry is defined in CoordSystem.View coordinates.
Only graphics of type ViewBackground or ViewOverlay are defined in view coordinates.
isWorldCoordinates Accessor Inherited ReadOnly boolean GraphicAssembler Whether the builder's geometry is defined in CoordSystem.World coordinates - the inverse of isViewCoordinates.
