hello,
I want to add 2 spherical vector.
It's possible to do an abstraction with 2 "sph2cart", adding cartesian
value, and then a "cart2sph".
yes of course, but this is how you add a spherical to a cartesian vector. if you want to add 2 spherical vectors, just add them element-by-element...
but I'm looking for an external (or abstraction) using less cpu : it's an operation that I need to aply on many vectors...
what machine are you running ? how "many" vectors ? on modern machines you really shouldn't notice (if you don't have 100 millions of vectors each second, but then you will have to wait for faster hardware rather than faster abstractions/externals)
