Hi Gabor,
Thanks a lot for the corrections in the spiral code, it looks great!!
I have another question, when I use the pdata-map! I only can make work the
array type "p" by putting (rndvec). Otherwise if I put only numbers in the
vector it doesn't do anything. I think I'm missing something about the pdata, I
already read the pdata and the deformation part of the manual, but I can't get
it at all.
I also understand that using pdata-set! we can access to a determined vertex,
but if we use pdata-map! all the vertices are going to be modified, am I right??
For example, if in this code I replace the "(rndvec)" for a "(vector 1 3 0)",
nothing happens:
(clear)
(define s (build-sphere 10 10))
(with-primitive s
(pdata-map!
(lambda (p)
(rndvec))
"p"))
Thanks,
Luis
