I went back and did some more work generalizing the code I use to create brick
walls, and some new code I wrote to create concrete sidewalks.  The new code
includes the ability to create American and English spanning layouts for bricks,
but still uses isosurfaces with brick pigment functions.

The tufts of grass are generated using parts of the makegrass.inc macros from
Gilles Tran.

Good work, especially for the bricks. Something I like less are 
fractures through the concrete. Those need to be "smoother" in their 
"irregularity" if you understand what I mean. :-)

Thanks.  The early versions of the fractures were too smooth, and I probably
went a bit overboard.  I'll play with dialing it back.

The floor looks great !  I think the light is too desaturated,
omnidirectional/ambient. Having a sun-like spot/direct light lower at the
horizon and grazing more from the side would reveal more of the specularity of
bricks and concrete (which should be quite low intensity less than 0.2 but high
roughness /size and diffuse multiplier should also be lower to let it reveal).
For realism possibly with a slightly warmer temperature than the sky sphere
lightbouncing through radiosity if you like that mood?

I made some updates after resolving some issues noted in the "transparent box"
thread.  I have another version where I tried to show tendrils of steam rising
from the sidewalk, the way a wet sidewalk would look in the heat of the day, but
they looked more like streaks of rain, which didn't match the fact that the sun
was out in the rest of the image, so I took them out.  I left some media fog
right on the sidewalk, though.

I like it. Starting to look like my unkempt garden. ;-)

This media fog effect is really interesting ! And the flower in the middle
really takes on some awesome dramatic composition through its lighting.
(there's still an issue with lack of perceptible finish for the red bricks. and
it's the only issue now. I believe it would help a lot since they take up so
much space in the image)

Thanks!  The sun in this scene was positioned to cause the triangular highlight
on the limestone block and light the downspout.  I placed the flower to face the
sun as well.  However, that essentially puts the sun just behind the wall, so
the face doesn't get lit by it except by ambient light.

If I could think of a logical reason for there to be another light source that
would show off the bricks, I'd add it in.  I suppose I could try changing the
time of day a little bit to get the sun just in front of the wall, and hope I
don't lose the interesting highlight on the block.

Reflection off another wall.   Like a white concrete wall.
Or a white gravel or sand area of ground.

Just add it in..   ;)
