createFromRenderGraphic MethodStatic

Create a TileTreeReference that displays a pre-defined RenderGraphic. The reference can be used by a TiledGraphicsProvider or as a DynamicSpatialClassifier. For example:

/** Add a TiledGraphicsProvider to draw a sphere into the specified viewport. */
export function addTiledGraphics(viewport: Viewport): void {
  // Create a scene graphic with a 1cm chord tolerance.
  const builder = IModelApp.renderSystem.createGraphic({
    type: GraphicType.Scene,
    computeChordTolerance: () => 0.01,
  });

  // Produce the sphere graphic.
  builder.addSolidPrimitive(Sphere.createCenterRadius(new Point3d(0, 0, 0), 20));
  const graphic = builder.finish();

  // Create a TileTreeReference to draw the sphere.
  const treeRef = TileTreeReference.createFromRenderGraphic({
    graphic,
    modelId: viewport.iModel.transientIds.getNext(),
    iModel: viewport.iModel,
  });

  // Register a provider to draw the sphere as part of the viewport's scene.
  viewport.addTiledGraphicsProvider({
    forEachTileTreeRef: (_vp, func) => func(treeRef),
  });
}

createFromRenderGraphic(args: RenderGraphicTileTreeArgs): TileTreeReference

Returns - TileTreeReference
