All Implemented Interfaces:

G3DRenderer
```
public class HermiteRenderer
extends java.lang.Object
implements G3DRenderer
```
Implementation of hermite curves for drawing smoothed curves that pass through specified points.

Examples of usage in Jmol include the commands: trace, ribbons and cartoons.

for some useful background info about hermite curves check out http://www.cubic.org/docs/hermite.htm Technically, Jmol implements a Cardinal spline varient of the Hermitian spline
