Hidden Line Removal shader

Hello. I was giving it a go at crerating a technical hidden line removal. I tried the Basic outline and it is almost it, but there is a strange flicker on the surfaces. I tried adding a "LOD"="0" on the outline pass of the shader with no luck. a sample of the cynergi apartment with the outline shader can be downloaded at:

Any ideas?

One word: hard

Something like this could (theoretically) be done in the pro version, by rendering a version of the image that has different colors depending on normals and depth, then running a dilapidated edge detect...

 

if its possible you are a rich man

I created a test with the toon shader. if the surfaces would not flicker it would be good enough.
