first of all, I'm sorry for the stupid question, but it's really
important to me to understand this thing :-)
I'm reading and studying the very nice book of Zwiebak and i'm working
on a quick calc about a plane identification:
(x,y) ~ (x+2piR, y+2piR)
This should identify the entire plane (x,y) with the other planes
(x+2piR, y+2piR) ... (x+4piR,y+4piR), etc.
I have no idea about the geometric view of this object... but I think
it shouldn't be a 3d obj.
Is it correct?
thanks in advance,
