This template is based on the <a href="https://github.com/jsxgraph/jsxgraph/blob/main/examples/parametricsurface3d_glider.html"><code>ParametricSurface3D</code> glider example</a> in the <a href="https://github.com/jsxgraph/jsxgraph/tree/main/examples">examples folder</a> included with the source code. Gliders on parametric surfaces have been available for a long time; this summer’s work just made their motion more intuitive by keeping them inside the surface’s parameter range.</p>
