Velocity V and HPB Q [SOLVED]

I have a particles velocity vector
I want to change that to a new velocity vector - by changing the Pitch Angle
From the Velocity Vector I can get the HPB
I can then change the HPB angles
Q: How do get the new velocity vector, given the updated HPB.

I've got a little further with this, but the more I read the more I think I'll need quaternions.
And it doesn't appear that they are supported in C4Ds Python SDK.
Any chance of that happening for R16?

All I can tell you is I've been looking for them too and it seems they are not in the Python API...

I think you might need to get into Matrix transformations for that..

you can create a vector by creating a Matrix from your HPB values and applying this Matrix to a default vector:
# create Matrix m = c4d.utils.HPBToMatrix(hpb) # default vector vec = c4d.Vector(0,0,1) # apply vec = m * vec
