I've developed a very simple 3D engine that can display solid geometries on 7650. It is still an early attempt to get it properly working (especially light shading and z-order with multiple objects displayed on the screen simultaneously).
It works pretty well on the Series 60 Concept Beta SDK, but at the moment I do not have an actual 7650 device, so I can't say if it will be worth to keep working on it.
I would be very grateful if someone could check it out on the real phone and tell me how it works (in particular the fps).
The url (for both download and OTA) is:
I tested your MIDlet and it works very smoothly in 7650.
I have also tested, quite time ago nearly samekind of
3D engine which can be founf from here:
