RE: [Plib-devel] Texture and blend modes

[Ben W. <be...@bg...>]

I think that glpopattrib(); will pop all attributes including anything you
have changed other then the gl_depth and gl_fog. Perhaps you want to
specific ones. 

Later Ben
I will have a look in my book about that. Later

Those are nifty little calls, when did they get added? :-)

So you are saying I could do something like the following:

  static int predraw( ssgEntity *e ) {

    glPushAttrib( GL_ENABLE_BIT | GL_DEPTH_BUFFER_BIT );

    glDisable( GL_DEPTH_TEST );
    glDisable( GL_FOG );

    return true;
  }

  static int postdraw( ssgEntity *e ) {
    glPopAttrib();

    return true;
  }

This unfortunately yields rendering problems ... can you see anything
obvious that I am doing wrong or misunderstanding here?

Curt.
