Question: Define and plot a hypersurface of (euclidian) R³

<p>Hello!</p>
<p> </p>
<p>I'd like to visualize my daily work and plot a curvature flow. First of all, I need to define and to plot a hypersuface. How do I do that?</p>
<p>Afterwards I'm going to calculate it's fundamental form and other geometric quantities.</p>
<p> </p>
<p>Kind regards</p>
