Opengl Support?

[Wobedraggled]

I just thought of thism but could games like GLtron be ported over?

Someone in the know, let us know.

there is no opengl support at the moment because the 2x has no 3d hardware.

Some people are investigating whether the 2nd processor can be used to run a software opengl renderer but it's barely in it's planning stages at the moment so don't wait on it.

So yes when this eventually does happen, gltron should be able to be ported over, but I doubt it will be able to run at a good speed, it all depends on what sort of power people can get out of the 2nd processor.

At best the perfomance could be improved twice. Problem with opengl is it's really demanding a hardware 3d acceleration. Z-buffer and alphablending are very costly to do in a software and these features are very common for opengl's aplications.

Perhaps instead someone could work on porting/writing a software 3D renderer and tweaking that. I am sure that better performance could be found from a software renderer instead of trying to emulate (sort of) openGL which is reliant on 3D hardware. Just a thought....

I've had Vincent (an OpenGL-ES software implementation) and TinyGL (an OpenGL subset with a software renderer) running on the GP2X, but they are horridly slow. Mind you, they are just straight ports with no optimizations done. There have been screenshots posted previously in these forums.

Other people have mentioned Yeti3D, which is a decent option if you wish to build a game like Doom. It is not very flexible, but could be extended to support poly meshes.

I'm not working on 3D stuff at the moment. Concentrating on getting my application framework going in 2D with hardware acceleration at the moment.
