Another test movie clip of Z depth depending variable line thickness. Drawing was done by Freestyle for Blender using a custom style module in which relative Z depth (i.e. a proportion of absolute Z depth to the difference between the maximum and minimum Z depth values in the scene) is translated into line thickness.

Simply an awesome video, T.K.! Great job. Really looking forward to using these z-depth modules in the official Freestyle release (that is, when Freestyle is officially integrated in Blender - oh the day!)

One thing you could fix,though (which would increase the render time) is the clipping distance on the camera - things fade away pretty quick, and for the last video it's almost as though you are looking down a smoked, foggy tunnel, though I didn't originally get that idea.

And for the first clip (of the three video clips,) it looks odd as it fades into the distance because the line thickness verses the object thickness are not consistent, so the line gets thinner faster than the object does and causes the spiral whatcha-ma-call-it-thingy (the spiral boxes,) to appear to get lighter (towards the color white) near the fading point - and then they fade out too quick.

But I still love the work - especially the second two clips.

GREAT JOB, TAMITO!!!!!!

Nice !
I wonder if it is possible to make the strokes work with vector blur(vector pass) ?

Thanks artislight for the comments. Frankly speaking, the quick fade-out is the effect I wanted to achieve in this movie clip. If you have got a strange feeling from the movie clip, then it's a success for me :) Not so quick fade-out (i.e. the line thickness that is consistent with Z depth) could be achieved by choosing adequate minimum and maximum thickness values (FYI, in the case of this movie clip, the values are 0.1 and 5.0, respectively). But I am interested in telling visual lies by means of the Freestyle renderer, since IMHO that's what NPR rendering is all about.

delic, yes it is possible to make strokes blurred by vector blur composite nodes. Retouching renderred strokes by composite nodes is an interesting topic in general and there would be various artistic possibilities in that direction.

Great, i need to use this for a project, but i cant make it work in windows, can you explain wich build to use, and how to really use it ?

please, thanks!

Tweaking Knobs, thanks for your interest. The build I used to render this movie clip was a Win32 build (revision 17661, IIRC, of the Freestyle branch) I uploaded to GraphicAll.org. The build was lately updated to a newer revision and thus is not available, but I have confirmed the latest Win32 build works fine with the style module in question. The style module is available in the BlenderArtists Freestyle thread:
blenderartists.org/forum/showpost.php?p=1268940&postcount=286
How to use: (1) Store the style module code into a file (say, relative_z_depth.py); (2) start Blender and enable the Freestyle renderer by turning on the Freestyle button in the Output tab of the Scene buttons (F10); (3) choose the style module file from within the Freestyle tab (to appear when the Freestyle renderer is enabled); and (4) render a scene (e.g., the default scene having a simple cube) by hitting F12 or pressing the RENDER button in the Render tab.
