Maybe another avenue of attack might be to add DEBUG_INFO messages to

I guess you have to use a osg::Texture1D instead of osg:Texture2D

Thank you for your suggestion I tried it but, again, no luck.
Di you manage to have coloured cartoon-shaded objects? If so, what
kind of texture did you use?
Thanks,

Hi every one,

I am subclassing MatrixTransform and overriding the accept(NodeVisitor)

Hi Shoham,
The issue you have is that the scene graph has holds internal ID's for
all the texture objects and display lists, you've deleted the graphics
context undernearth it so these ID are no longer valid, but the scene
graph doesn't know that they are invalid so when it dispatches them to
Hi Richard,
You could play multi-pass tricks like done in the osgdepthpartion
example, or just manage the visible distance so that the furthest
distance is never too far away. For instance a common trick is to use
Fog to make far objects fade away until eventually nothing beyond a

Hi Glenn,
I can't really give a straight answer without spending some time on
the code, but it does sound like CullStack should be returning the

that is exactly the problem, it seems from the source code that the

think one should write another shader that reads the current color and

Hi Michele,
Cell shading doesn't have specular highlights normally, if you want
this you'd need to do it in a custom shader. What you may need to do
is subclass from osgFX::Carton to add your own shaders, or just set up
the scene graph by hand to do the effect you want.
Robert.
On Dec 17, 2007
Thank you very much Robert,
for now I will try to modify the shader in a
subclass/cut-and-paste-class of osgFX::Cartoon so that it can handle
color-material and cartoon-like speculars, if I manage to have
something working I will post it back here (crossing fingers).
Regards,
Michele
Hello Michele,
Cell shading doesn't have specular highlights normally,
Actually, since the color for cel shading is determined according to
the angle to the light, you can do a fake specular highlight by just
playing with your color ramp (the 1D texture). For example, it could

I think I found the problem. I am using version 1.2 (which I forgot to
mention, again), and CullVisitor does not push and pop the viewport on the

Thanks again -gw

From OSG 1.9.x onwards the OSG hasn't included VS project files,
