Stream Processing to Generate 3d Meshes in Unity3d?

Is it theoretically possible to generate complex meshes on the fly in unity using GPU Stream processing? What library and code could implant stream processing into unity?

Here is a video demo of mandelbox generated in realtime with “boxplorer”:

NOTE!!! if you have a slow laptop edit the .CFG file to 320 pixels or you will have 1fps! fast graphics can do 20-60 fps.

All of the .CFG files are different shapes, move them next to the exe and rename to see them.

In Unity you can not generate geometry in shaders.
Unity only supports SM2 and SM3, not SM4+ (geometry shaders or tesselation), as such you would need to generate rendered geometry on the CPU using the Mesh class
