How to extract the position and rotation of a homogenous matrix? Thanks Jack

Is the homogeneous matrix composed of others than translational and rotational transformations? What kind of orientation representation do you need to get?

In general, look out for the keyword "matrix decomposition".

I think I don't have to worry about orientations because I am dealing with bones :)
The original example uses one 3x3 matrix for rotation and a vector for position.
Now, I am using D3DXMATRIX, as that is homogeneous, I want to mimic what the example does....

One more question:
Is 3x3 matrix the same as a 4x4 matrix without translations?
| R | 0 |
| 0 | 1 |

Thanks
Jack
