Hello,
can somebody give my quick example of building height_field
with i.e. function { x+z+sin(x+z) } (instead of loading it from .bmp).
Where can I read more about it in help ?

#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

It is admittely hard to find (and this will probably be fixed). It's
in section 6.7.11.16 of the documentation.
