Can you try this example.php:
<?php

/***************************************************************

* All rights reserved
*
***************************************************************/
require_once("delaunay.php");

// Turn off all error reporting
error_reporting(0);

// example 1
$triangle=new DelaunayTriangulation();
$triangle->main();

$vis=new visualize("C:\Temp\\",$triangle);
$vis->genimage();

?>

First off, I'm using Linux and it doesn't have C:\Temp\ folder nor the drive C. You need to change it to fit your need. I think you are using Apache und Windows. Second can you try to run the script from the console? My script isn't meant to start in a browser. I wasn't aware that's can be a problem. The error message isn't so important at the momemt, please ignore it. Thank you.

Hey man,

the fix is from 2014!

Did you awake from coma?

You need the new example file!
