Thanks Ron, that's it. Never thought of planar warp. Actually I'm not sure
I completely understand how it works. The helpfile is a bit cryptic for
this one.
Is it like rendering plane{y 0 Texture}, and use the resulting image as an
image map? An imagemap is projected in the xy-plane, that's the reason for
the absence of a rotation around the x-axis. If this is so the translate -
0.5 can be commented out, but it can't, it gives a different result.
Re-reading this and after some more experiments I see the light (I think).
A translation <-0.5,-0.5,0> also does it. It's just like an imagemap.
All this looks like a promising way to make old wall with parts of the
stucco coming off.
