Hi Ray, i hadn't tried it with incidende at 0 for some reasom - must try that...
But just to be really annoying i wonder if you (in your infinte wisdon
) can advise me on this: the LitSphere methodhttp://andy.moonbase.net/archives/tag/arthttp://www.cs.utah.edu/npr/papers/LitSphere_HTML/
I can get some interesting effects using the Gray Ball directly into the material port but i'm wondering how i can make it respond to lights - that should be possible right? Mudbox seems to use this method and you can change the lighting in that? I tried just plugging an incidence into the grayball's multiplier port but that didn't quite do it...
Can you help me out on this?
EDIT: also there are these techniques in this slideshow: http://www.slideshare.net/pakital35 Light Warping
and Radiance Scaling
- they seem very interesting too... i might have to move or rename this thread to a more generalized quest for NPR..
Oh and yeah i've seen the Tod Akita, the line work in the image i posted is pretty much based of that, great stuff indeed!
EDIT 2: more cool NPR stuff: http://www.valvesoftware.com/publications/2007/NPAR07_IllustrativeRenderingInTeamFortress2.pdf
i understand most of this except "warped diffuse" - looks cool...
