OpenGL ES versus OpenGL

Question

What are the differences between OpenGL ES and OpenGL ?

Answer 1

Just like to add that OpenGL 3.3 and OpenGL ES 2.0 are mostly interoperable, by using a subset of the features of OpenGL 3.3. My custom C++ engine uses the same API calls, with a few defines, for Android/IOS/Windows/OSX/Linux.

Among the key differences are:

• lack of geometry shader support
• no min/max blending (there may be an extension for this)
• no Quad List primitive
• more restricted texture formats (especially regarding floating point)
• glGetTexImage is not available
• there is no Transform Feedback, same for several other advanced features

There are also many other differences, but that covers several of the important ones.
