Converting core::quaternion to and from hkQuaternion

[3DModelerMan]

How do you convert a core::quaternion to a Havok hkQuaternion? Is it safe to assume you can just copy the members like you can with vectors (I've already converted those.)? I'm working on a Havok physics animator, and I need to convert between the two types of quaternions.
Thanks.

I'm pretty sure it is just that, try and see if it works

Sometimes the ordering is changed. There is w,x,y,z. Sometimes they are stored WXYZ other times XYZW.

It`s exactly the same- just copy the members:

Code: Select all

irr::core::quaternion irrQuat = // your definition here
hkQuaternion hkQuat.set(irrQuat.X, irrQuat.Y, irrQuat.Z, irrQuat.W);

Works for sure. I was using Havok some time ago.
