Subject: How can I evaluate and visualize code instead of running it.

I am using a tree and traversing down a tree to generate opengl code
How could I easily list the opengl code that I am generating, instead
of running it?

  def applytransform
    GL.PushMatrix();
    GL.Translate(*@Translation);
    GL.Translate(*@jointP);
    if @parent != nil
      GL.Translate(*@parentjointP);
    end
    GL.Rotate(*@rotation);
    GL.Translate(*@jointP.minus);
  end

  def traversetree
    GL.Clear(GL::COLOR_BUFFER_BIT);
    GL.PushMatrix();
    applytransform
    @children.each {|childnode| childnode.traversetree}
    drawprimitive
    GL.PopMatrix();
    GLUT.SwapBuffers();
  end
