[osg-users] Fog and desired usage

2008-08-18 Thread brettwiesner
Hi, I just had a couple of questions about the desired usage of the fog state attribute. 1) What does it mean to have different fog states on different branches of the scene graph? Would this have any effect? 2) Is the desired usage to set the fog attribute on the root node? Thanks,

[osg-users] Update callbacks occur in between calls to glBegin and glEnd?

Hi, I was wondering if update callbacks are suppose to occur in between calls to glBegin and glEnd? I think this test code demonstrates that they do. I'm using a glGet command (in this case glGetIntegerv) and checking for it's error code. From the open GL docs: GL_INVALID_OPERATION is

Hi, Recycling context id's is something that seems fixed in 2.6.0. I'm not sure if you can keep a graphics context around without a window however you can keep the scene graph around. Just hold onto a ref ptr to the root node of your scene graph. You should be able to open a new window and
