quaternion

Currently I have this to rotate my 3D model that rotates on it's local axis independent from the world's axis:

// Rotate model with Right Thumbstick
modelRotation -= pController.ThumbSticks.Right.X * mRotSpeed; // float value

What I'm trying to do is rotate the model using quaternion and not by a matrix.

I've searched for tutorials, but have found none that explains thoroughly on how to achieve this. Does anyone know how to I can use quaternions to rotate my model or a complete tutorial?

How do I implement a quaternion based camera?

as seen on Game Development - Search for 'Game Development'
I looked at several tutorials about this and when I thought I understood I tried to implement a quaternion based camera. The problem is it doesn't work correctly, after rotating for approx. 10 degrees it jumps back to -10 degrees. I have no idea what's wrong. I'm using openTK and it already has a… >>> More

I have Euler angles from a right handed system that I am trying to convert to a left handed system.
