<div dir="ltr">Hi Andrew, <div>I am contacting you because of the parametric ellipsoid class you created.

<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>
