Is there a way to initialize using OpenGL ES 2.0?

[jgranick]

Hi!

Do you think it would be possible for this to work using OpenGL ES 2.0?

I know that OpenGL ES 1.0 is hard-coded into the EGL initialization code, but I wasn't sure if you knew if it would be that simple, or if there would be other problems that would occur?

Thanks

The main problem was that I didn’t have a good way to expose the ability to switch between ES 2.0 and ES 1, and most of the apps that were using SDL at the time seemed to be for desktop OpenGL 1, which was closer to ES 1 than ES 2.0.
I didn’t really try ES 2.0 – I think making the EGL changes should be sufficient.

Alright, then I'll try to take a look. On webOS, they back-ported an attribute from SDL 1.3 (2.0), SDL_GL_CONTEXT_MAJOR_VERSION.

On the OS they defaulted to OpenGL ES 2.0, but required that you set SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 1); if you needed 1.1 instead.

Maybe that would be the "right" way of handling it, with the exception of using OpenGL ES 2.0 by default

That seems pretty reasonable. Feel free to do the same, if you’re feeling ambitious. I won’t have time to get around to it for a little while yet.
