Hello, I have a question about rational bezier curves (that is those with w (weight) coord).Rational Beziers do not behave correctly when increasing/decreasing control point's weight. The curve should go closer to the point with increseaing weight. Following picture showes that very well - http://commons.wikimedia.org/wiki/Image:Rational_Bezier_curve-conic_sections.svg But with OpenGL evaluators (at least on my ATI Radeon using both Ubuntu Linux and Windows XP) it does not act like that. Has anyone encoutered such problem ? THX Virgee
