matrix question

Hi, I have a little wierd problem. You see, I want to be able to determine a vertex-point inside a glPushMatrix() thing... My code looks something like this:

glPushMatrix();
  //load and render a model
glPopMatrix();
  

Inside that matrix, I want to determine a vertex which is valid outside that matrix... Do I make any sense?? Well, lets put it this way. In that matrix I get a point which is x = 1.5 y = 0 z = 2.0 But in the "world" matrix it's rendered at x = 10.5 y = 2.0 z = 4.0 I want to somehow transform the vertex from its local coordinate system to the world coordinate system. Is that possible? [edited by - dario_s on May 14, 2003 7:30:53 PM]
