/**
|
|
* 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.
