I'm looking for a simple yet complete camera implementation (library) for OpenGL. My use case is rendering volumetric models - which I'm visualizing with glut. But my current camera implementation is a bit buggy.

After googling I found a few implementations such as those found in NeHe however they don't have all the functionality I'm after, specifically:

1. Left, Right
2. Strafe
3. Rotation about viewing a开发者_如何学JAVAxis
4. Arbitrary translation of viewing point

Any DirectX solutions that can be easily converted into OpenGL will also be appreciated.

Since I'm not sure about the question, I'm going to tentatively answer with a tutorial of mine :

Hope that helps. If it does not completely fulfills your needs, don't hesitate to explain exactly what is wrong, and I'll edit my post.
