Yes, pyeuclid had "cross" and "dot" product of vectors. I am
impressed with it and curious how it works: the Vector3 class
is available without any prefix euclid:
v = Vector3(111.., 222.2, 333.3)
works without requiring as in:
v = euclid.Vector3( etc...)
I am really intrigued by that. OTOH, I also am somewhat
aprehensive about using something that affects the program
writing after importing "euclid", without any need to explicitly
refer to euclid. Looks rather risky to me. What does that do
to the namespace?
Thanks for bringing this to my attention. I confess that I
would be hapier if euclid was accessible in a "standard" manner
with prefix of module name for classes in the module.
