API Reference > imodeljs-frontend > Views > ScreenViewport > pickDepthPoint pickDepthPoint Method Find a point on geometry visible in this Viewport, within a radius of supplied pick point. If no geometry is selected, return the point projected to the most appropriate reference plane. pickDepthPoint(pickPoint: Point3d, radius?: number, options?: DepthPointOptions): { plane: Plane3dByOriginAndUnitNormal, source: DepthPointSource, sourceId?: string } note The result plane normal is valid when the source is not geometry or a reality model. Parameter Type Description pickPoint Point3d Point to search about, in world coordinates radius number Radius, in pixels, of the circular area to search. options DepthPointOptions Optional settings to control what can be selected. Returns - { plane: Plane3dByOriginAndUnitNormal, source: DepthPointSource, sourceId?: string } A plane with origin from closest geometry point or reference plane projection and the source of the depth point.
