Hi chippwalters and PaQ and everyone.

If you have Rhino+Thea Render it's also very easy and very very fast to generate realtime pseudo ambient occlusion
rendering in three easy steps :

1) Copy past object from Moi to Rhino

2) In rhino assign to all objects a simple white diffuse material

3) Play realtime viewport rendering with TheaRender plugin

Here's a quick and dirt video capture (sorry for the very bad quality but I recorded with my phone and left hand...)
