title: How does 4x4 matrix work in 3d graphic?
body: <p>I am learning about 3d graphics and have stumbled upon matrixes, which I don't fully understand. I have a 3d object, with topology, points in coordinate system and ECS (4x4 matrix of the object).
  ECS is:</p>
  
  <pre><code>-1.1247455413666E-32 , 1.83690953073357E-16, 1                    , -95  , 
   1                   , 6.12303176911189E-17, 0                    , 604  , 
  -6.12303176911189E-17, 1                   , -1.83690953073357E-16, 200.5, 
   0                   , 0                   , 0                    , 1    , 
  </code></pre>
  
  <p>What does each line separated with comma mean ? Are these translation vectors?</p>
