The FAQ is for 1.2 http://www.vis-sim.com/osg/osg_faq_1.htm#f40 so it may be
different for 2.x not, I'm still stuck on 1.2 until the new year

 

But you can push all bits along the lines of 

 

glPushAttrib( GL_ALL_ATTRIB_BITS );

 

glMatrixMode( GL_PROJECTION );

 

glPushMatrix();

 

glMatrixMode( GL_TEXTURE );

 

glPushMatrix();

 

glMatrixMode( GL_MODELVIEW );

 

glPushMatrix();

 

//

//

//

 

Your code here...

 

//

//

//

 

glMatrixMode( GL_TEXTURE );

 

glPopMatrix();

 

glMatrixMode( GL_PROJECTION );

 

glPopMatrix();

 

glMatrixMode( GL_MODELVIEW );

 

glPopMatrix();

glPopAttrib();

yup. I might be missing something though.
Don;'t know intelligent way to do other than to push each mode,attr, then
pop them.
Is there an overall one?

Hi all,
 
What is the easiest way to protect myself from a GL app that I am calling
that isn't cleaning up after itself?
I think that it is changing the states or attrs, or vertex arrays or
something, so that osg lazy eval gets messed up.
 
We have called
state::dirtyAllModes
dirtyAllAttributes
dirtyAllVertexArrays()
 
but it doesn't seem enough.
 
Maybe we are missing a state.
 
Is there either a getAllStates() that we can call to do this to, or a
disableLazyEval, or something?
 
Thanks,
 
Chris

Re: [osg-users] Mixing GL

2007-11-21 Thread Stephen Northcott 

There's a pretty good example here of mixing systems.

You could apply it either way around.. The way I have gnerally done it  
is to put OSG inside the other applications loop.


http://www.3drealtimesimulation.com/osg/osg_faq_1.htm#f40

Not sure how deprecated it is now, but worked for me not so long ago..

Kind regards,
Stephen.
