This ticket will add support for visualization of convex hulls through the projectToBorder function and 2D clusters by adding the clusters parameter to the zplot function.
The projectToBorder function is a function that works together with the existing convexHull function. It takes two parameters:
1) A Convex Hull created by the convexHull function.
2) A matrix of 2D points to project to the border.
The projectToBorder function then projects each 2D point to the Convex Hull border and returns a matrix with these points.
Using this approach the border of a convex hull can be visualized in interesting ways.
Sample visualizations are attached.
