I am using the Jitter Physics engine which gives a rotation matrix:

M11 M12 M13
M21 M22 M23
M21 M32 M33

And I need it so OpenGL can use it for rotation

GL.Rotate(xr, 1, 0, 0)
GL.Rotate(yr, 0, 1, 0)
GL.Rotate(zr, 0, 0, 1)

Initially I Tried

xr = M11
yr = M22
zr = M33

[1 0 0]
[0 1 0]
[0 0 1]

Which did not work, please help, I have been struggling on this for days :(

Re-Edit

The blocks are stored in text files with Euler angles so it needs to be converted or the rendering engine will simply fail.

I am now using the matrix in the text files.

Example Block

1,1,1                      'Size
0,0,0                      'Position
255,255,255                'Colour
0,0,0,0,0,0,0,0,0          'Rotation Matrix
