Hi, there, Paul.
I have tried to adapt your PickHandler class to solve my specific
problem, but I couldn't. Please, help me out. Honestly I haven't completely
understand it (when you check for Intersections and stuff like this) but I
imagined that all I had to do was to put my own methods after the "if
(_selectedNode.valid())" condition.
Well, let me elaborate a little bit more on my software's current
situation.
There is a Point class, that is osg::MatrixTransform's daughter. Each
Point's instance has a geode child, which carries a sphere with a certain
color. What I need to do is change the sphere's color after this shape was
selected by mouse picking. I've tried creating a method changeColor, that
belonged to the Point class, and I've made the PickHandler a daughter of
that class, so that it would have access to the method.
Specifics of the method aside, what do I have to do to call that
method? Is it simply by writing "_selectedNode->changeColor();" in the above
mentioned condition's nest? That doesn't seem to work very well.... Do I
have to declare _selectedNode as a global variable before the definition of
the class? If yes, what kind o pointer would it be?
By answering this, you'll make someone eternally grateful to you!
