Hi
By default OSG will have display list turned on which means the drawing
is cached and thus when you change something it will not be reflected,
if your changing tings a lot you might want to disable display list
alternatively you can tell OSG to rebuild the display list with a call
like myGeometry-dirtyDisplayList();
I would recommend a searching the forum archive as well as this has been
discuss many times and there are many ways in which you could edit
geometry on the fly

Subject: [osg-users] Moving a line and its vertices
Hi,
I have created a line in my scene based on the osggeometry example. I
create the line and it displays fine, but I also need to change the
end-points on the line dynamically as the simulation progresses. I
started out by re-setting the vertex array data at each step in the
render loop, but that did nothing. The line stayed exactly where it was
when it was first initialized. I then tried creating a new vertex array
and calling setVertexArray at each step, and this blew up spectacularly
after a few steps. Is there any example of how I am supposed to get my
line and its end points to move dynamically in the simulation?
Thank you!
Cheers,
David
