[PyOpenGL-Users] Quaternion slerp checked in

[Mike C. F. <mcf...@ro...>]

Not sure if others were interested in it, but I just checked in a method 
for OpenGLContext.quaternion.Quaternion that lets you do spherical 
linear interpolation (slerp) between two quaternions.  This is useful if 
you want to animate between two rotations using fractional values.

I'm thinking I may try to grok the spline-on-rotation interpolation code 
(so that with 5 or 6 rotations you get a nice fit curve that doesn't 
make the rotations mechanically switch direction at the sample points). 
  It looks pretty hairy though, so might just leave it with slerp.

Enjoy yourselves,
Mike
