I want a band of mountains on the horizon that drop to foothills and finally
a plane as z approaches 0.
#declare MountFunc = function {"ridgedMF" <1,5,3,1/3,50>}
with
function{ y + (MountFunc(x*z,0,z)*5)} // (note the x*z)
doesn't work. While the mountains become less prounounced, the plane is at
the level of the highest peak rather than the foothills.
As a kludge, function{sqr(y) + sqr(z) + (MountFunc(x,0,z)*5)} is okay with a
separate shape for the plane, but I would prefer option a).
Any ideas?
BTW has anyone got any samples of good parameters for ridged mf?
