Matrix/HPB to XYZ and vice versa

Hello,
I've got some models in two different softwares, when one is using XYZ rotation and the other (cinema 4d) uses HPB/Matrix.
I couldn't find a way to get my model's XYZ via Python (only Matrix), so I'm looking to see how can I translate rotation matrix or HPB to XYZ and vice versa.Thanks in advance,
Sheilan.

Angles are always store in radian internally. 47° is the same as 0.820304748437 radians.
you can convert using this function DegToRad
I think that's what you have with the flag ROTATIONORDER_XYZGLOBAL
m = op.GetMg() # convert the matrix to XYZ xyz = c4d.utils.MatrixToHPB(m, order=c4d.ROTATIONORDER_XYZGLOBAL) # convert from radian to deg for i in xrange(3): xyz[i] = c4d.utils.RadToDeg(xyz[i]) print xyz

hello,
what come to my mind is those functions MatrixToHPB and HPBToMatrix
Or maybe i didn't understood your question.

@m_magalhaes Hello,
You misunderstood. I'm able to get Matrix & HBP but I need XYZ. I'm looking for either MatrixToXYZ or HPBToXYZ (preferably the first one).
Thanks,
Sheilan.

hello,
there's different flags you can use in that function, all values are differents.m = op.GetMg() print c4d.utils.MatrixToHPB(m, order=c4d.ROTATIONORDER_DEFAULT) print c4d.utils.MatrixToHPB(m, order=c4d.ROTATIONORDER_XYZGLOBAL) print c4d.utils.MatrixToHPB(m, order=c4d.ROTATIONORDER_XYZLOCAL)
what software are you using ? What are the types of XYZ (vector floats) ?
Cheers

I tried creating a cube and setting it's HBP manually.
HBP 47º 0º 0º
XYZ 0º 47º 0º
and the result is
Vector(0.82, 0, 0) Vector(0, 0.82, 0) Vector(0, 0.82, 0)
What I need is a result of Vector float that shows
(0.0, 47.0, 0,0)
(XYZ) as a result.

@m_magalhaes said in Matrix/HPB to XYZ and vice versa:
convert the matrix to XYZ
xyz = c4d.utils.MatrixToHPB(m, order=c4d.ROTATIONORDER_XYZGLOBAL) # convert from radian to deg for i in xrange(3): xyz[i] = c4d.utils.RadToDeg(xyz[i]) print xyz
Works perfectly. Thanks!
