quaternion from entity pan tilt roll

I'm trying to produce a quaternion rotation from an entity's pan tilt roll parameters in a dll...this is what im trying so far... doesn't quite work as orientations are wrong. I need this for a D3DXMatrixTransformation matrix...

D3DXQuaternionRotationYawPitchRoll
(
&qrot,
D3DXToRadian(_FLOAT(ent->pan)),
D3DXToRadian(_FLOAT(ent->tilt)),
D3DXToRadian(_FLOAT(ent->roll))
);

You don't need quaternions here: Use ang_to_matrix for getting a D3DX transformation matrix.

For converting an angle to a quaternion, you can either use a DirectX function, or use vec_cross to get the rotation axis and the angle about that axis. At least that's the theory, I haven't done it yet.

ok, ang_to_matrix works for what i want... thanks.
