Martinez algorithm for polygon Boolean operations, PHP library.

martinez-rueda-php's Issues

When performing union in several multipolygons, some of them are lost.

mpoly1.json
mpoly2.json

$arr1 = json_decode(file_get_contents("mpoly1.json"));
$arr2 = json_decode(file_get_contents("mpoly2.json"));

$subject = new \MartinezRueda\Polygon($arr1);
$clipping = new \MartinezRueda\Polygon($arr2);

$result = (new \MartinezRueda\Algorithm())->getUnion($subject, $clipping);
echo json_encode($result->toArray()), PHP_EOL;

Differences of polygons or other unions works as expected, but with this particular files, some output is missing, see attached output.jpg.

Using the martinez-rueda javascript implementation, everything goes well.

codepen javscript implementation

Can anybody offer some help?
