PHP使用php_stl计算STL模型体积和表面积

<?php

require_once 'vendor/autoload.php';

use PHPSTL\Handler\VolumeHandler;
use PHPSTL\Handler\SurfaceHandler;
use PHPSTL\Reader\STLReader;

$reader = new STLReader();
$reader = $reader->forFile('./111.stl');

$handler = $reader->setHandler(new VolumeHandler());

$volume = $reader->readModel();

$handler = $reader->setHandler(new SurfaceHandler());

$area = $reader->readModel();

var_dump($area);die;
