Hi
this is perhaps a stupid question, but I can't wrap my head around it.
Here's what I want to do:
I have an object attached to the root of the scenegraph, and a hud,
displaying some additional info. I want to connect a certain point of my
object with a certain point in my hud. For this I have to transform the
vertice of the object into the space of the objetc attached to my hud.
I can get the world-coord of the vertice via osg::localToWorld but how
can I transform this vertice into the "space" of the hud? Do I have to
apply the view and projection matrices of the cameranodes in the nodepath?
I there some built-in method in osg to transform from one local space to
another local space across multiple projections?
Thanks for any pointers,
Stephan
