### frames/DemoFrames01
Demonstrates how to create a 3D path and attach cylinders to it at regular intervals with the correct orientation.
- The path is constructed using the `path3D` builder.
- A rectified copy is created to be able to sample it at equal-length intervals.
- We call the `frames` method on the rectified contour to generate a list with 100 transformation matrices which
make it possible to attach oriented 3D objects at specific locations in the curve.
- We finally use the transformation matrices to draw cylinders along the 3D path.
The orbital camera extension enables interactive 3D view manipulation.
A fixed random seed is used to make sure this demo outputs a specific output. We can delete the
`random` arguments to get a unique result each time the program runs.

### hobbycurve/DemoHobbyCurve02
This demo creates a list of random 2D points, finds the alpha shape contour for those points,
and finally makes that contour smooth by calling `hobbyCurve()`.

### hobbycurve/DemoHobbyCurve03
This demo shows how the [org.openrndr.shape.ShapeContour]'s method `hobbyCurve()` can be used
to round contours with linear segments.
