Translation: Translation refers to moving an object to a different position on the screen. Formula: X = x + tx Y = y + ty where tx and ty are translation coordinates The OpenGL function is glTranslatef ( tx, ty, tz ); 2. Rotation: Rotation refers to rotating a point. Formula: X = xcosA - ysinA Y = xsinA + ycosA, A is the angle of rotation. flos newport ri
