Tom,
everything is Sketchup, no other software involved.
The floor is a single face with an Autocad hatch pattern applied to it.
The fading is the result of the applied sketchy style with depth cue on.

Hi,
this bar has very little 3d elements in it.
All those doors and windows are just 2d Autocad lines, applied on single faces.
Same mo for the walls and the cabinets above the bar.
Saves time and keeps the model light to handle.

this is no post production, just native sketchup;
a style with sketchy lines and a touch of fog. Done in a second and yet a nice effect, don't you think?

some of you, from the old SU forums, will remember the techniques from Denis and Grant.
I just felt the urge to practice once more. Hope you like it.

Hi to all of you,
I added some nice images on my blog, have a look! http://3dnet-international.blogspot.com/.

hi digicent,
unfortunately it's not a standard style, but a combination of a sketchy style and some Photoshop.

Hi,
I made these in a couple of hours, for advertising purposes.
It gave me a chance to practice my own version of the watercolor technique once more.

done !
Craig did a wonderful job helping me with some SU problem a while ago.
