» 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" |
