What projection matrix and world transformation do I need to have an isometric projection?
I found that the easiest way is to just use a Transformation Matrix like:
And just adjust the Rz(a) to 45º and Rx(g) to 35.264º
Or if -z to Rz(a) to -45º and Rx(g) to 215.264º

What projection matrix and world transformation do I need to have an isometric projection?
Another way to formulate an Isometric projection is with the matrix:
$
\left[ {\begin{array}{cc}
cos(\phi) & sin(\phi)sin(\theta) & 0 & 0 \\
0 & cos(\theta) & 0 &0 \\

I found the answer, someone pointed me to the spherical coordinates system and it is the exact match. as shown here
The only difference is that, this assumes phi is actually calculated from the z-axis ...
