Vector Math

I3Position and I3Direction

New operations:

• addition

• subtraction

• scalar multiplication

• dot products

• cross products

• magnitudes

• conversions

Works with normal math operators in C++ and Python.

example:

I3Position p(1,2,3), q(4,5,6);
std::cout << p+q << std::endl;
// I3Position(5,7,9)
std::cout << p-q << std::endl;
// I3Position(-3,-3,-3)
std::cout << 2*p << std::endl;
// I3Position(2,4,6)
std::cout << p*q << std::endl;
// 32.0
std::cout << I3Direction(p) << std::endl;
// I3Direction(Zenith (deg): 143.301, Asimuth(deg): 243.435)
