Hi,
i'm looking for a function to pick a single point in the scene.
I've had a deep look in the picking tutorial, bit couldn't get down to
the single point.
I've created a point cloud by the geometry class. All points are in one
geometry "node".
# I like to pick one point
# I like to select a bunch of point (e.g. by a quader)
I've just found the OpenSG funktion OSGIntersectAction. As it was shown
in the example the intersection accept just a line (vector). I assume a
line can not intersect a point. What I might need is a volume object,
like a Frustum.
Is there already a function for picking / selec points in OpenSG
available and I couldn't find it? Or must I implement this funktionality
by my own, if yes how?
Thanks
Rainer
