[SciPy-user] quaternion and slerp interpolator, and all that
Wed Jun 3 16:39:56 CDT 2009
I have a related question. I have programmed a couple of
quaternion-valued functions and used arrays with a customized numpy
dtype for it. Something like
dtype = [('r',np.double),('i',np.double),('j',np.double),('k',np.double)]
Now, I am wondering if there is an easy way (e.g. using cython) to
define a custom quaternion scalar type and make numpy aware of it. I
found some information in the numpy book about this topic but couldn't
find any example code.
If anyone has working example code, that would be great -- as I said,
ideally using cython, but c code would be fine too.
