Unfortunately, the website doesn't allow you to do that for free anymore, but I found an even better one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4i_S1NwKjN8.html
In the core it is, but it has a few more features and is competely free. It generates 3d images and you can outline them yourself, which is really useful.
