Here's a wall, made out of a height field... eventually it will be much
nicier...
The height field was rendered in povray as a 1024^2 hf_grey_16 bit png.
There is a pigment { rgb 1} and no reflection, the height field is
smooth, and there are no subsequent normals applied...
I wonder where the problem comes from...
Here a glimpse of the code:
height_field { png "BrickWall01.png" smooth
scale <1,0.1,1>
[...]
}

It seems to me that the edges are too sharp and height fields are not
designed to handle properly slopes like these, so you see lots of
artefacts on the sides of the bricks. You can try to have smoother
slopes on the sides.
Your other problem with the surface of bricks is not very obvious, you
might try to increase the resolution of your height field, sometimes,
especially when doing a zoom on a height field you need to go up to
resolutions like 7000x7000 ...
I hope it helps,

Or, you could go and try to use functions and smoothen
the perhaps obvious pixels by averaging several
slightly misplaced image-maps of the heightfield. But I'm
not too firm on functions, so thats just rambling about
stuff I've heard... :-)
