A Switch node is the parent of a ScalarInterpolator node that changes the illumination of a Cylinder geometry by a PointLight. The ScalarInterpolator has been "switched out" by setting the whichChoice field to -1. The result should be, the ScalarInterpolator should continue send and receive events, and animate the illumination of the Cylinder geometry.'/> |
