I don’t know about the SDL renderer for 2D games with regards to GLES2, but SDL GLES2 works fine here after I fixed the CreateContext line in SDLActivity.java to specify an appropriate list of
attributes (requesting the version I want).
Granted I’ve only tested on Tegra hardware here, but it works fine.On 08/06/2011 06:36 AM, William Dyce wrote:
I don’t think the SDL port currently supports ES 2.0 at the moment. The higher Android OS versions wouldn’t display anything until I forced GLES 1.1 to be used instead: apparently as of Android 2.2
it’s all GLES2 unless you specify otherwise.I’ve stripped out all the calls GL-only now - apparently it should be more efficient this way anyway (for desktop computers I mean). Android’s still not keep on texturing my polygons though: guessing
I’m still using something that doesn’t work properly in the embedded version. Other people have had similar issues - just type “android texture black” into Google and you get all kinds of stuff:

You really should drop glBegin/glEnd calls, specially if you plan to move later on to OpenGL ES 2.0 devices, which don't support this type of calls any longer.

A consensus on this subject seems to be lacking, so which flavor gives the best performance on a modern mobile gpu? -f or -x? I can't speak for Andriod, but every iOS device (forever) has had a FPU, so do NOT use fixed, it'll just slow it down. Stick with floats (especially for vertex data.) The next question is -- unsigned bytes for color data or floats? That's something I'm about to try, so I can answer that question later. I suspect unsigned bytes will be much faster (as memory bandwidth is your big concern here.) As for Williams question, I'd do a rewrite on my non-OpenGL ES desktop application first -- go to VBOs for everything, first, and eliminate all the glBegin/glEnd pairs. Make sure all your VBO indexes fit in unsigned shorts (no unsigned int indexes in OpenGL ES). You're going to want to do that before you even attempt a OpenGL ES port.
