Can anyone give me a simple answer about the exact difference between OpenGL and WebGL? I need more specific on the following:
programming semantics, API’s inheritence, API’s extensions etc.
I’ve looked at the following site but it is not very clear to me:
http://www.khronos.org/webgl/wiki/WebGL_and_OpenGL_Differences
WebGL is “OpenGL ES 2”, not plain OpenGL (the ES stands for ‘for Embedded Systems’). So there’s the first difference. OpenGL ES is essentially a subset of OpenGL. In addition, WebGL is almost the same as OpenGL ES 2, but has some subtle differences, explained in the link you provide. There’s not much to add to that link, it’s a pretty clear explanation of what is different between OpenGL ES 2 and Webgl.
