<div dir="ltr">My point is that I am setting a cutting plane for the ellipsoid inside the parametric equation. I am leaving point x,y,z =0 after the plane, also with derivatives DU and DV. So in the borders it doesn't look nice with a resolution of 64 points. I attach a pic to let you get an idea. Thanks</div>

<pre style="margin-top:0px;margin-bottom:0px"><span style="font-family:arial;white-space:normal">but when I move to a bigger resolution like 1024 it gets completely slow. I tried moving to OpenGL mapper and actor but nothing. My graphics card is an AMD W7000 (fast) so its not hardware problem. What can I do to tweak it and get a smoother look?</span></pre>
