In the model panel you can choose a discrete surface, on which the discrete
geodesics shall be shown. Pick a starting point for the geodesic by holding
"i" pressed and clicking at any point of the surface.
Curve panel controls:
| Slider "Length" |
Analytic length of geodesic curve. |
| Slider "Direction" |
Starting Direction of geodesic curve. The direction is given by an
angle in the tangent space at the selected point. |
| Slider "Element Index" |
Index of the element, which contains the starting point of the
geodesic curve. |
