Even better, if there is a way to tell whether intersecting geometry is static

I had some people bug reports about the use of samplerRect in the osgOcean

Since this has caused problems for me, i noticed you still have a dangling

Hi Paul,
If I understand the problem correctly you can use a screen aligned quad with a
post render camera that has an orthographic projection.
i.e.

0.0, -1.0), osg::Vec3(screenWidth,0.0,0.0),
Ok, I think I get you.
You could achieve that by using a texgen node to compute a set of projected
texture coordinates for the plane and then map the texture onto it.
osgReflection would be a good place to look for that. You'd want a similar
approach but instead of using the prerender stage

Unless you explicitly ask the osg to clone your model's geometry it will share

Hi All,
I'm getting the following error/warning when I run my program. Can anybody tell
me what it means?
Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)

Cheers,

Look at depth of field, it works very well for underwater scene, going some way
to spoof the blurring in the distance caused by water. I believe there's a nice
implementation in the book ShaderX3
As for sun-beams or god-rays check out the book ShaderX5 there's a good article
on a multipass

Yes that's the case. Great, thanks for the rapid response. I'll give it a

I'm having difficultly getting a some geometry to always render infront of a
scene. I use an absolute matrixtransfom to move a cockpit model relative to the
camera position. However, as i move the camera around it intersects with
geometry in the scene.
Previously I achieved this by using a
Hi all,
I've created a cockpit model which moves around along with the camera movement.
To do this I've attached an update callback to the cockpit's transform. I pass
the viewers main camera into it and use that to set the cockpit transform to
the inverse of the main camera's view matrix.

I'm trying to work out the world coordinates of vertices in my shader,
and I'd like to check my understanding of a few things.
At the moment I manually go through the graph and grabbing the
transformations en-route to the target geode and create the matrix
myself, pass this to the shader, and
This was mentioned a while ago, search the forum for Problems with
osgViewer and ActiveX, there was a chap that was trying to do it in IE
so I presume you could get some relevant info from him.

Hi all,
Just a quick one for you.. when I use the following code:
osg::Vec3 eye, centre, up;
float dist = 0.f;
viewer.getCamera()-getViewMatrixAsLookAt( eye, centre, up, dist );
I seem to get the same value for both eye and centre. Is that supposed
to happen? If so how can I get
Ha sorry my mistake.. I though dist was an output parameter.
Must think before I speak/post!
