Hi Jean-Sébastien,
i can send the code tommorrow, then you can review it, test it
and my we can improve a new boosting algorthime for next
generation of OSG. How would look like your timetable, do you
feel like having some time left to work on the osg integration or
do you just like finish the
Hi,
I have been trying to work out what the example osgdistortion is trying
to do with an overview to looking at doing warping to compensate for
multiple rotated cameras and curved/angled screens.
Part of the way through this investigation I read the thread on view

Hi!
I've exported an object from SolidWorks and stored it in .osg format.
Now I'm trying to get rendered the edges of an object (without triangles
as are seen in wireframe in the osgviewer - only the edges wireframe).
What would be best possible solution(s) to achieve this? I'd like to

Hi
i don't really understand what you like to render.
(A) wireframe mesh
(B) silhouette
(C) cartoon?

A CullCallback may store Statesets and push/pop them on the cullvisitor.
It would be nice if those GL Objects get released as well.

Basically only outline of an object. Are there any osg solutions?

If you want to render _just_ the outline, then the method I suggested will
still work, but you've just got to switch off rendering to
Hello to all interested in raytacing!
Everyone's talking about optimizations, kD-Trees and stuff...
Does anyone at all have a raytracer that supports everything OSG is able
to model/represent?
I'm talking about multitexturing, terrains, shaders, support for huge
scenes, and all the rest...

Hi Joachim,
i agree completely with the your point of view. but one important thing is,
and only this part i am working on
is the fact that we haven't an accelerated line intersection test
implemented for triangle represented topology. $
if we make use of the drive manipulator, we can drop in ver
Hi Adrian,
ok, I agree.
You said you built a kD-Tree on top of cow.osg. What exactly are you
doing with the vertex/triangle arrays then?
How much overhead in terms of memory does this produce? Would this
really scale for large scenes?
regards,
Joachim

Hello all,
i try to do Multipassshading in OSG v1.2.
I have written my own shader class in the class I use the osg::shader
for shading. At the time my shading code looks like that:
Shader::Shader(void) {
//creating program
program = new osg::Program;
//creating shader
vertShader = new
I think osgFX is where you want to look. That nodekit has some classes
Technique, Effect etc that allow you to define multiple passes. I haven't
used it personally but a developer in our group has used it quite a bit. If
you look at osgfxbrowser example, I think it has sample code but I'm not
Hi Adrian,
The code I posted is from a gui that I am trying to get to work with osg. I
have derived an OSGview class from the gui's Container class to show a 3D view
as the background of the widget. The gui works fine if I don't call
osgViewer::frame(), but nothing will display on top
Hi Sven,
i must agree Gerrick, one possible way to implement a multipass shading
in OSG is using the osgFX libary. It's stable and work well, but i think
a big disadvantage of this libary is the inflexibility. Each Shader you
will have to bind must be implemented separatly by overwriting special
