I am using EPIC (http://www.mindcontrol.org/~hplus/epic/) in my game and was wondering if anyone has added support for quaternion based orientation prediction into it. Or if anyone has a suggestion on how to handle orientation prediction in a similar way to how EPIC predicts position.

EPIC uses a template, so you could instantiate it with <4, float> as arguments.
The output you get won't be normalized, so normalize after you read a value.
Other ways of interpolating a quaternion might be to interpolate in axis-angle space, or interpolating in Euler angle space. You might want to experiment with converting to/from different spaces when interpolating.

Thanks hplus! Using 4 floats and normalizing the quaternion did the trick.

Thanks for the great extrapolator. We plan to use it for all sorts of networking goodness on Zero Gear.
