Javascript-форум - threejs Чтение stl файла

Пытаюсь с помощью threejs считать файл с диска и отобразить. Файл - бинарный stl. В результате сцена окрашивается в алый цвет (думаю проблемы с камерой) либо вообще ничего не отображается. В консоли вижу строчку "THREE.WebGLRenderer 61 three.min.js:417". Прошу помочь.
