General Module Function
2D_Overlay provides a module that applies any connected module's output to the Viewer's 2D overlay. Objects in the overlay are not transformed (rotated, zoomed, panned). These objects are locked in position. This provides a mechanism to apply graphics like drawing title blocks or company logos.
However, you must ensure that the object sent to the 2D overlay fits inside its limited spatial extent. The 2D overlay is a window with an x-extent from -1.0 to 1.0. The y-extent is dependent on the aspect ratio of the viewer. With a default Viewer having a 4:3 aspect ratio, it is three-quarters of the x-extent (e.g. -0.75 to 0.75).
Module Input Ports
Optionally one or more objects to be children of this object. Multilevel object hierarchies can be built in this manner.
Module Output Ports
The renderable NON-TRANSFORMABLE object that is connected directly to a viewer.
