Help with quaternions to have model look at point.

[vivienneanthony]

Hi

I'm trying to figure quaternions. If I have a Point Vector(4,3,1) with a Quaternion for example (.7,1,0.0). How do I go about it to look at something with a Point of (10,5,4) but making make sure the Quaternion Rotation angle is directed at the point?

In english, I need to get a Drone to move to a vector difference while facing that new location.

I'm using this engine functions.

Try using matrices. Write your own matrix class or download?

Directing a drone would be a good, but fairly straightforward application in 3D geometry I expect.
