Hello,<br><br>I am interested in using a spatial object with the shape of a torus or toroid. I've been reading the documentation online, and I think that I only have to re-write a couple of functions: ValueAt(), IsEvaluableAt(), IsInside(). Are these the only functions I need to rewrite or should I also type a constructor or other things alike. Can you help me with some guidelines, please?<br>
<br>Thank you<br><br><br clear="all">Antonio Foncubierta<br>
