This is the second episode of the adventures of "Harold on the road", 
in a version probably (very) close to the final one.

	A few credits : snail model by G.Tran, Micra car (the closest one) by 
R. Bui, other cars by various authors found at 
http://dmi.chez-alice.fr/models1.html   .
	Trees made with Arbaro and PovTree. Edges of the main objects obtained 
with my PovEdge program.

	Comments, critics, etc. are welcome !

Love it!   Where's the first episode?  I'm curious what approach you took
for making the road.

Ohyes, this is wonderful. It's interesting how the deliberately flat
texturing looks so realistic in this image - I guess it's the contrast with
the outlined objects... very nice indeed.

Arbaro sounds nice, though written in java: certainly faster with polygon
trees than the many CSG macro generators.  Is there any reason why povray
SDL would not handle it, other than performance perhaps?

I've seen PovEdge before and it seems to have matured a lot to be able to
produce  such smooth round edges.  I myself am not really into
non-photorealistic raytracing, but this is definetely a plus for the povray
community. :)

I'm curious about render time. :)

I love the mix of cartoon/realism in that scene :-) And the caption is just 
delicious!

Thanks. The first episode, I don't think I have posted it on this ng. It 
can be seen here : http://tuabiht.chez-alice.fr/PovEdgeEx/harold1.jpg
The caption reads "Of course it was a shortcut, but Harold knew he would 
need all his vigilance to go through the roadsign fields".

The whole ground (road + landscape) is a single parametric isosurface. 
In fact, the curve of the road in the xz plane is a parabola, and I have 
computed "local coordinates" for points on the road (U : position along 
the road, V position across the road). This a kind of analytical UV 
mapping, which allow me to get easily the texture of the road, and 
placement macro for objects on the road.

Thank you. I simply tried to keep the landscape textures compatible with 
the cel-shaded cars (so, simple flat textures).

The nice point about polygon trees is instantiation : multiple copies of 
a single tree cost the same resources as the single tree.

Thank you. I have used the version posted here a few weeks ago. Getting 
the edges for most of the cars was really a question of minutes.

> I'm curious about render time. :)

	With the simple textures and the unique light-source, rendering was 
quite quick (~1 hour at 3600x4800 !). Because of the many objects and 
edges, parsing becomes a bit long though (~15 minutes).

Ah, it is nice to see people like the caption ! ;-)

This image would have great potential to become an awesomely realistic
image if you dropped the outlines, used some more elaborated textures
and perhaps a photorealistic sky.

  Some people have commented that they like the mix between realistic
and cartoony elements in the image. I have to be honest, I don't really
like that too much myself. It makes the image just look odd. Either it
should be completely cartoony or completely realistic. This kind of
mix between the two just doesn't work very well, IMO.
  It would be interesting to see a photorealistic version of this
image.
