Editing OpenGL ES (section)

==={{Anchor|2.0}}OpenGL ES 2.0===
OpenGL ES 2.0 was publicly released in March 2007.<ref>{{cite web |url=http://www.khronos.org/news/press/releases/finalized_opengl_es_20_specification/ |title=Khronos Press Releases - OpenGL ES 2.0 |publisher=Khronos.org |date=2007-03-05 |access-date=2010-12-23 |archive-url=https://web.archive.org/web/20101228111715/http://www.khronos.org/news/press/releases/finalized_opengl_es_20_specification/ |archive-date=2010-12-28 }}</ref> It is roughly based on OpenGL 2.0, but it eliminates most of the [[fixed-function]] rendering pipeline in favor of a programmable one in a move similar to the transition from OpenGL 3.0 to 3.1.<ref>Edward Angel, Dave Shreiner, ''Interactive Computer Graphics: A Top-Down Approach with Shader-Based OpenGL'', 6th Edition, p. xxi-xxii, {{ISBN|978-0-13-254523-5}}</ref> Control flow in shaders is generally limited to forward branching and to loops where the maximum number of iterations can easily be determined at compile time.<ref>{{cite web|title=The OpenGL® ES Shading Language|publisher=Khronos.org|access-date=2013-02-16|url=http://www.khronos.org/registry/gles/specs/2.0/GLSL_ES_Specification_1.0.17.pdf}}</ref> Almost all rendering features of the transform and lighting stage, such as the specification of materials and light parameters formerly specified by the fixed-function API, are replaced by [[shader]]s written by the graphics programmer. As a result, OpenGL ES 2.0 is not [[backward compatibility|backward compatible]] with OpenGL ES 1.1. Some incompatibilities between the desktop version of OpenGL and OpenGL ES 2.0 persisted until OpenGL 4.1, which added the <code>GL_ARB_ES2_compatibility</code> extension.<ref>{{cite web|url=http://www.opengl.org/registry/doc/glspec41.core.20100725.pdf|title=The OpenGL(R)Graphics System: A Specification (Version 4.1 (Core Profile)|date=July 25, 2010}}</ref>
Actual version is 2.0.25.<ref>{{cite web|url=https://registry.khronos.org/OpenGL/specs/es/2.0/es_full_spec_2.0.pdf|title=OpenGL ES Common Profile Specification - Version 2.0.25 (Full Specification)|last1=Munshi|last2=Leech|first1=Aaftab|first2=Jon|date=2 November 2010|website=registry.khronos.org|archive-url=https://web.archive.org/web/20250312175627/https://registry.khronos.org/OpenGL/specs/es/2.0/es_full_spec_2.0.pdf|archive-date=12 March 2025|url-status=live}}</ref>

The Khronos Group has written a document describing the differences between OpenGL ES 2.0 and ordinary OpenGL 2.0.<ref>{{cite web|url=https://www.khronos.org/registry/OpenGL/specs/es/2.0/es_cm_spec_2.0.pdf|title=OpenGL© ES – Common Profile Specification 2.0.25 (Difference Specification)|date=November 2, 2010}}</ref>
