Twisted quads vs. Expressive quads

[jeremydouglass]

As discussed in your previous post

Polygons Distribution with loops

Let’s save the coordinates of a little square: float[] coords = new float[] { -10, -10, // x1, y1 10, -10, // x2, y2 10, 10, // x3, y2 -10, 10 // y4, y4 }; Think of it like a metal mold or template for pouring a little rubber stamp. We can make the stamp and use it all at once by passing the coordinates to beginShape() or beginShape(QUADS). Here is a stamp method to do that: void stamp(float[] coords) { beginShape(); for(int i=0; i<coords.length; i+=2) { // read two numbers e…

there are multiple ways to add randomness to a set of points that are not twisted. If you are growing out in four quadrant directions, you won’t give you every possible random quad – but it has a lot of variation, but concave shapes will be quite rare.

One way to get more frequent and “expressive” concave shapes is to do random points (or a random walk of points) and test for line-line intersection to detect invalid crossings.
