Summary
|
Classes that define Quaternions and their operations
|
|
Description
|
Classes that represent and manipulate quaternions. Contain definitions
for basic arithmetic functions in a static class.
Quaternions are an extension of the idea of complex numbers, and
a quaternion is defined as:
q = a + b*i + c*j + d*k
In 1844 Hamilton described a system in which numbers were composed of
a real part and 3 imaginary and independent parts (i,j,k), such that:
i^2 = j^2 = k^2 = -1 and
ij = k, jk = i, ki = j and
ji = -k, kj = -i, ik = -j
The above are known as "Hamilton's rules"
