Along with OpenGL, support OpenGLES

[kwadroke]

Devices like the Raspberry Pi, Android phones and devices, Beagleboards and other embedded systems do not support full OpenGL. Please add support for OpenGLES for those and other systems.

Bear in mind, this is the first time I've ever touched any opengl stuff, so I'm not familiar with what opengles even is... quick googling makes me think it's a subset of opengl.

I am using gtk for all the mouse/keyboard events and for windowing stuff, and for the main game loop, so, without some considerable work, I'm stuck with gtk. For opengl, I'm using gtkglext, which allows using opengl on a GdkDrawable. It's not clear there's any other reasonable way to combine gtk and opengl. It's also not clear to me whether or not gtkglext supports opengles, or whether it requires full opengl. To some extent, it is what it is. What's driving me down this road is performance problems with the software renderer. So... does it work right now for you on raspberry pi?

This thread is not encouraging... :(

shit And I was hoping this change would make it work better on raspberry pi, not make it quit working altogether.

An idea....

It occurs to me that the "Main Screen" is really the only one that needs the opengl accelleration. I could potentially change the code to allow building a limited client which supports all the screens except "Main Screen" and do not require opengl. That way, the Rasp. Pi could at least be used for all those screens, though you'd still need a system with OpenGL support for the main screen.

So instead of "snis_client" and "snis_server", you'd have "snis_client", "snis_limited_client", and "snis_server". Better than nothing. I'll try to get that working.

a Limited client could work. Although I'd still like an all Raspberry Pi setup.

Ok, just pushed up a change that makes a limited no-opengl client. Let me know if you encounter any issues with it.

[smcameron]

Ok, for now, the limited client has main screen support too. However, this will likely cease to be the case at some point as I make the opengl 3d rendering code better.

For now I'm going to close this issue. Feel free to re-open it when it breaks at some point in the future - which is pretty likely. I will try to make sure the other screens besides the main screen continue to work without opengl though.
