How can I blend a rgba-image over a Performer rendered window? There is a
part in the insight documentation that tells me to do such actions in the
DRAW_Callback. But the example shows only a command like DrawOverlay() and
I don't know how to do that. Is there a way to load and put an image on
the screen only by using Performer own functions? Another problem we have
is to attach a camera (pfChannel) to a moving node (pfDCS) to follow the
scene from the perspective of the object. Like a camera mounted on the top
of a car. A possible solution would be to calculate the eye Position in
every CULL callback by hand. Is there some better way, like using the DCS
as input device for a pfTransformer?
I would be very happy if anyone could show me some good example file or
some lines of source.
Thank you very much,
Steven.
