SoHandleEventActionSetPickRadius Method |
Sets the radius (in pixels) around the viewport-space point through which the ray passes when doing ray picking.
Namespace: OIV.Inventor.Actions
Default is 5 pixels. Ray picking is performed when OIV.Inventor.Actions.SoHandleEventAction.GetPickedPoint() is called.
Note: By default the pick radius set here is only used when testing the ray against lines and points. To enable pick radius for triangle based geometry use the OIV.Inventor.Actions.SoHandleEventAction.EnableRadiusForTriangles(System.Boolean) method.
