question: public boolean divideAndDraw ( GL2 gl , Point2D center1 , Point2D center2 , QuadCurve2D curve , GLEntity shape1 , GLEntity shape2 , QuadCurve2D last ) { QuadCurve2D left = new QuadCurve2D . Float ( ) ; QuadCurve2D right = new QuadCurve2D . Float ( ) ; curve . subdivide ( left , right ) ; boolean resL = drawCurve ( gl , center1 , center2 , left , shape1 , shape2 , last ) ; boolean resR = drawCurve ( gl , center1 , center2 , right , shape1 , shape2 , last ) ; return resL || resR ; }
target:  Divide the given curve in two half, and call drawCurve on each part.
