Thanks, that worked OK. I still have one problem. I see drawing only when
drawn straight ahead. If I draw on other locations, I don't see any drawing.
It seems that drawing and field of view are somehow out of sync??

2006/12/11, Gordon Tomlinson <[EMAIL PROTECTED]>:

 Its not too hard to do, the way I have do this is to derive my own node
from osg::Drawable

and the main function to them create is virtual void drawImplementation(
osg::State& state ) const ( there are a few others )

But you do all your opengl in drawImplementation(...) make sure you leave
Opengl in the same state you entered otherwise you will screw OSG's state
management

And in your osg::Drawable constructor call  setUseDisplayList(false)
otherwise you will only get called once, also you will have to see the
bounding box up..

See the OSG examples on creating nodes and simply replace drawable with
your custom drawable


Works well for us.... ( apologies for not having a sample I can share at
this time)



Best Regards

*Subject:* [osg-users] How to render one node just by using generic OpenGL
API

I want to render one node using glBegin() and other OpenGL commands. The
point is, I don't have static geometry, so I would like to render it on my
own.

thanks
