## Demos
### DemoDelaunay01
[source code](src/jvmDemo/kotlin/DemoDelaunay01.kt)
This method sets up a graphical application using the OPENRNDR framework
to visually demonstrate Delaunay triangulation on a set of points scattered
along a circle with Poisson disk sampling.
The application features the following:
- A central circle with a defined radius.
- Points generated within the circle using a scatter algorithm that
maintains specific spacing and avoids clustering.
- Delaunay triangulation computed from the combined point set.
- Rendering of triangles that are part of the Delaunay triangulation.
- Visual styling with dynamic color shading for better clarity of layers
and triangle order.
This method demonstrates concepts of computational geometry and procedural
rendering.

### DemoVoronoi01
This program generates a Voronoi diagram within a defined circular area and visualizes it.
The program performs the following:
- Defines a circular area and a rectangular bounding frame within the canvas.
- Uses Poisson Disk Sampling to generate points within the circular area.
- Computes the Delaunay triangulation for the generated points, including equidistant points on the circle boundary.
- Derives the Voronoi diagram using the Delaunay triangulation and the bounding frame.
- Extracts the cell polygons of the Voronoi diagram.
- Renders the Voronoi cell polygons on the canvas, with a pink stroke on a black background.
