title: How to draw NURBs with OpenGL ES
body: <p>In OpenGL NURBs can be drawn using <a href="http://glprogramming.com/red/chapter12.html" rel="nofollow">evaluators</a>. But it seems evaluators were <a href="http://en.wikipedia.org/wiki/OpenGL_ES#OpenGL_ES_1.0" rel="nofollow">removed</a> from OpenGL ES spec to make it light weight. In that case, how can one draw NURBs using OpenGL ES API?</p>
