This is a question about how to construct Voronoi based on a boundary

[Wayne8887]

This is a tutorial on how to use Voronoi on the official website

Now I have made a Tyson polygon according to the instructions on the official website.
code：list var0 <- voronoi([{10,10},{50,50},{90,90},{10,90},{90,10}]);

This is the output result

But when I input the interface I want, such as using the example code provided by the official website.
list var1 <- voronoi([{10,10},{50,50},{90,90},{10,90},{90,10}], square(300));
But there was no result displayed

Here is my code

Sincerely, may I ask how teachers can solve this problem

I think you just forgot to draw the result of the voronoi operator, here is one example:

model voronoi

global {
	list<geometry> points <- [{10,10},{50,50},{90,90},{10,90},{90,10}];
	list<geometry> clusters <- voronoi(points);
	init {
		write clusters;
	}
}


experiment a {
	
	output {
		display scene {
			graphics "points and clusters"{
				loop p over:points{
					draw p color:#black;
				}
				loop c over:clusters{
					draw c color:#red wireframe:true;
				}
			}
		}
	}
}
