Hi,
I have POV-Ray (3.6.2) and found a typo in the help files at the end of
"Combining isosurface functions" (2.3.3.3.6), with this:
function{fn_A(x,y,z) + pow(Blob_threshold,(Fn_B(x,y,z) + Strength))}
function B (near the end) has a capital F, however the declared function has a
lower case f:
#declare fn_A = function { sqrt(pow(y,2) + pow(z,2)) - 0.8 }
#declare fn_B = function { abs(x)+abs(y)-1 }
POV-Ray displayed an "undeclared identifier" error message when trying to run
it, and it took me ages to spot the typo.
Regards,
