This sub-module will enable you to create 3d-models you can use in any available 3d-package to create real 3d-images with refraction-effects, shadows and whatever you want. You could even create solid objects to put onto your (real! :-)) desk using a 3d-printing-service! But, beware, this can be like living on a edge. It can happen that you put much effort into a particular scene, and finally you will end with nothing. On the other side you could achieve outstanding results, which you could not get with any other technology.
Please credit and or link to this resource if you use them to create your images. For more information please read this
