Howdy everyone,
I have objects under a group node called Objects that are rendered. When the objects get too far
away, Z-fighting occurs. Would it be possible to fix the Z-fighting by instead of adding the objects as a
child of Objects, create two

Hi,
I have problems with understanding the use of a NodeCallback.
Can anyone explain me what a Nodecallback is doing?
A NodeCallback is a class that implements a method ( operator() ), which
is called when a particular traversal (update, cull,

Hmm, only other thing that comes to mind is the two sampler uniforms.
Are they set to different values in the CPU code? That's all I can

Seems like you mess up sampler uniforms setup. You unit declared as unsigned int,
and osg uses different gl functions to set uniform with int and unsigned values
(which is right thing), and samplers uniforms must be set with signed int

Hi,
Guys, you are great! Thanks to both of you for your good explanations! :D
Another little question: I guess a Camera::DrawCallback is a callback that gets
added to a osg::Camera and that gets called (operator()) every time the camera
renders

Ok, but what do these 4 types exactly mean?
I guess a PreDraw callback gets called BEFORE the camera renderes and PostDraw

Paul's right. I checked the spec. glPolygonMode is not supported by
OpenGL ES. That was a surprise to me as
