Based on [Is there a better way to draw gradient colored ellipse?](https://discourse.processing.org/t/is-there-a-better-way-to-draw-gradient-colored-ellipse/22220/4) I wrote a 3 point gradient which might look like this: PShader gradient; PShape shp; int[][] coordinate = { {0, 150}, {100, 450}, {200, 500}, {150, 750}, {400, 850}, {500, 750}, {450, 450}, {500, 100}, {175, 0} }; void setup() { size(600, 1000, P3D…
