Hi,
Does any Marmalade library contain an ArcBall/Trackball utility aimed at 3d model rotation and touch event handling (mainly for touch screens)?

I'm VERY new to Marmalade Development and C/C++ (I'm a Java dev with some history of OpenGL ES via Monotouch/OpenTK) and am just try to get up to speed with some functionality I'll require for my game idea.

I know there are MANY implementations of ArcBall/Trackball, my question is, is there one that integrates easily with Marmalades pre-existing class library or a well used extension (i.e. OpenGL ES libraries etc.).

Below is the URL for a potential solution, I'm including here just in case no-one has an answer but were looking for something similar themselves (I'm trying to avoid the Quaternion mathematics etc., lazy, I don't mind migrating the code below to Marmalade's graphics primitives, if necessary).

Thanks
