Matrix is a row dominated 4x4 matrix. Realsoft 3D uses matrices to represent spaces and transformations for geometric objects.

  | a0  a1  a2  a3 |
  |                |
  | b0  b1  b2  b3 |
  |                |
  | c0  c1  c2  c3 |
  |                |
  | d0  d1  d2  d3 |
  +----------------+

Matrix operations (such as concatenation, scale, translate etc. concatenate the new matrix on the right side. In other words, the latest operation is executed the first using 'first in last out' order.
