draw the square, then rotate the triangle

have a global variable rot

and in ur draw function

do this


drawSquare (); //ur square function or the code for ur square

glRotatef(rot,a,b,c); //a b c definces the vector u wana rotate about

drawTriangle ();

rot+= c; // c = ur angle inclination

or push and pop...

u really should do a tutorial, or read a book on what rotation is, and about how the transformation matricies work and such.

about the CTM and how each transformation multiplies the CTM with its new matrix.
