Yes I know, there are a lot of very nice ao effects producing osls’ which can achieve in some degree such a thing but it is only in some degree. And the reason is that the ao effects producing osls’ create, always, a fading out too in the lines appearing in the edges of objects. You never have a clear cut line on the edges (as is in the image below –the result has been achieved by modelling and not shading-). So, is there a chance to produce a clear cut line producing osl shader? A good line shader with edge crease degrees and line thickness options?
Such a shader may be useful in many shading tasks, especially when used in various node combinations, for producing edge decay effects, transparent line renderings, npr descriptions of hard surfaced models (as an alternative to Freestyle) etc.
So, any good osl programmer here to consider a solution? : - )
