For a quick overview of all (new) language constructs you can take a look at the OpenGL ES 3.0 Reference Card and compare it to the OpenGL ES 2.0 Reference Card. The update of the language includes among other things new language constructs that give you access to the new features of OpenGL ES 3.0 (e.g., 3D textures) but it also makes changes to already existing features (e.g., the lookup function for a texture2D). To use the new features provided by OpenGL ES 3.0 you need to use the new OpenGL Shading Language (GLSL 3.00) in your shader. OpenGL ES 3.0 is fully backward compatible with OpenGL ES 2.0 which means that all your shaders targeted at OpenGL ES 2.0 keep running just fine. Nonetheless, it is important to keep in mind that only the aforementioned devices are capable of OpenGL ES 3.0 and not all devices that run iOS 7. So if you want to target OpenGL ES 3.0 there are already a lot of new devices out there that do support it. Desktop OpenGL does not support this.With the release of iOS 7 and the introduction of the iPad Air, the iPad mini with retina display and the iPhone 5S Apple has brought OpenGL ES 3.0 to their mobile devices. OpenGL ES 2.0 requires the specification of precision modifiers for attributes, uniforms and locals. On Web, the graphic stuff is handled by WebGL. Please note that support for OpenGL ES 3.0 is experimental on iOS.

To prevent your application from being shown to unsupported devices in the Play Store, add one of the following lines to your Android Manifest: On Android Open GL ES 2.0 and 3.0 can be used. OpenGL 4.5 should be able to fully emulate GL ES 3.1. GL ES 3.1 & 3.2 have done a lot of work to bring the API’s functionality significantly closer to it’s desktop counterpart. Please note that MacOS only supports the OpenGL 3.2 core profile.

For mimicking GL ES 3.0 on desktop, one can specify the exact OpenGL version, that should be used. On desktop, OpenGL 4.3 provides full compatibility with OpenGL ES 3.0. GL ES 3.0 is the successor of OpenGL ES 2.0. To mimic GL ES 2.0, libGDX does not request any specific OpenGL version, so the driver will be more forgiving. GL ES 2.0 is roughly based on Open GL 2.0, however, there are some incompatibilities that weren’t resolved until Open GL 4.1. On Desktop, libGDX is mapping all its graphics calls to OpenGL.
