Detailed Description

template<typename T>
class fe::Matrix< 3, 4, T >

Matrix for 3D transformations.

Indexes

    0   3   6   9
    1   4   7   10
    2   5   8   11

represent

    Rot Rot Rot Tx
    Rot Rot Rot Ty
    Rot Rot Rot Tz

with the columns

    Direction Left Up Translation

The operator(i,j) addressing for a 4x4 matrix is:
    00  01  02  03
    10  11  12  13
    20  21  22  23

For translation on the right as shown, this is stored column major. Note that a few references place translation on the bottom, so this would act like row major.
