how to create a 4X4 matrix for directX with natnet?

[hangon]

Hi,
I'm trying to create a 4X4 matrix for directX from the rigidbodies streamed from arena (x y z qx qy qz qw). I have some quatToMatrix examples but not sure how to expand the matrix with the translations. Thanks for any pointers.

This should work with "Right Hand Coord" check box off in Other tab.

D3DXMATRIX m;
D3DXQUATERNION q(qx,qy,qz,qw);
D3DXMatrixRotationQuaternion(&m, &q);
m._41 = x;
m._42 = y;
m._43 = z;

Thanks Yoshi
that's very neat.
