Currently in osgswig you cannot directly override osg.Drawables in the
target scripting language.
This is partly because we have not enabled SWIG directors for this
class, which are responsible for such cross-language inheritance.
Also, Drawables are pure virtual/abstract which doesn't play
Hi Tommy,
Good to hear you are getting a better understanding of osgViewer, but
please don't use GLUT, it really is awful for anything more than
single threaded, single window basic OpenGL demos. osgViewer has
inbuilt into it far far more powerful and flexible cross platform
windowing support.
I'm looking to do the following in OSG, and I wonder if I'm on the right
track (before wasting time needlessly): have two render processes run in
parallel on two different GPUs, have one render a scene to texture and
let this texture be read by the other process and mapped to an object in
a
Hi Ferdi,
osgViewer::CompositeViewer runs all of the views synchronously - one
frame() call dispatches update, event, cull and draw traversals for
all the views. So for you case where you want them to run async, this
isn't supported. Supporting within CompositeViewer would really
complicate the
Hi Eduard,
The description of the problem sounds to me like the normals of the
geometries aren't of unit length so messing up the lighting model,
this can happen if there are transforms that scale the scene. You
can enable GL_NORMALIZE or GL_RESCALE_NORMAL modes on the scene to fix
the lengths
Hi Eduard,
if you look at Geodes Mesh6 Model and Mesh7 Model you'll notice that they don't have
any normals whatsoever. I'd suspect they're just picking up normals from one of the
previous nodes.

I have done all, but I can not find the file. I donwloaded the OSG and VPB
from the version svn related. I did everything but I do not know why, the
cmake does not fill that correspondence(osg_gen) and I have to do by hand.
Could you tell me where is osg_gen file?
