I'm actually aiming for a sandy environment.

In that case it works. Looking forward to the finished product

I think the ground fog is too overpowering.

Color is too saturated, perhaps?

Should you decide to accept this mission, a creative intersection of
f_rounded_box() (the brick) and f_torus() with creative arguments (the holes)
can give you a start.

Still far from that, but getting ahead.
Parsing is getting painfully slow for my taste, so I'm resorting to generating
include files using #write...
Next step will be to equip the SDL-generated sand mesh with normals to smoothen
it.

Well, what could give me a start is to hear that there already *are* such
functions in the first place ;)
Thanks for pointing me the right way. For now I guess I'll stick to my
home-brewn solution though.

I like how the focal blur simulates heat vibration. Perhaps if you make the
sky a paler blue, or more yellowish, the heat will be more intense. The blue
color tempers it somehow.

I've always liked the trick of eating away objects with other traced objects.
Especially using HFs as the impinging ones. (I made some irregular, sharp rocks
in a similar way, by randomly rotating a bunch of instanced HFs around a sphere.
Didn't use trace for that, though.)
Good job!

There's yet more to be "eaten away". Yummy - cruchy glass...
Before anyone complains: I'll move the far-off brick to somewhere else. And I'll
bring the sun around to the back again - the bricks on the right lack quite some
depth at this angle.
(Does anyone have an idea why the sand in the glass comes out so incredibly
green- / yellowish?)

Among other things, Alain saw fit to write:

I don't remember having counted the number of holes in bricks, but I'd say 3
holes is too few for the bricks I remember seeing. Searching google images
for "ladrillo" (Spanish for "brick") gives images with many more holes. And
actually searching for "brick" gives images with 10 holes.

Must be the effect of the glass color? reddish+bluish=yellowish?? Don't ask
me about the physics... :-)
I have seen this effect too.
