$film->addImage($img);                                      // 将该图像输出添加到渲染胶片
$render .= $film;


// 五、输出场景文件 scene.scn，及渲染文件 render.cfg
echo $scene;
$handle = fopen( "./DemoScene/scene.scn",'w+');
fwrite($handle,$scene);
fclose($handle);

echo $render ;
$handle = fopen( "./DemoScene/render.cfg",'w+');

fclose($handle);




// // 六、启动渲染器
// $cmd = "luxcoreconsole -o ./DemoScene/render.cfg -f ./DemoScene/scene.scn 1>./DemoScene/render.log 2>&1";
// $output;
// $returnVar;
// exec($cmd,$output,$returnVar);

// if( $returnVar == 127 ){
//     throw new \Exception("Please install the luxcorerender bin file in the system directory correctly,Or add to the system environment variable");
// }
