[osg-users] StateSet UpdateCallback on a camera

2012-07-06 Thread Christian Schulte
Hi everyone, I'm facing a problem in our flight simulation environment, where we want to make the fog camera dependent ( in order to have cameras without fog for simulation control). I tried to follow the 2009 thread "[osg-users] Set fog in the canera StateSet" and

[osg-users] behavior of osg Tesselator with alpha transparency

Hi, I was trying to generate a textured halo around a flat (2D) geometric shape that is supposed to fade with distance without using any GLSL. The shape is a convex polygon. My approach is to create a polygon with a hole, where the vertices on the outer ring has alpha transparency 0 and those on

Hi Cedric, thank you for your hints. In fact I have a little idea about skeletal animation, but I’m new with this in OSG. I am reading and looking for info, but it’s still a bit messy for me. Is there any simple (as simple as this topic can be) example or tutorial anywhere? Thank you.

Thanks Tim for your response, I will try your solution with an empty UpdateCallBack for the camera. Concerning multiples views in my application, I didn't post my whole code, but we are in a class derived from osgViewer::CompositeViewer. I understand that Fog and Light are not SceneGraphNodes,

2012-07-06 Thread Frank Kane
From what I've read, captureCurrentState just returns the current state attributes in OSG - it's not actually capturing the current GL state. But, you could flip the problem on its head and capture the actual OpenGL state just prior to calling your library, and then restoring it when your
