Subset of the OpenGL 3D graphics API designed for embedded devices such as mobile phones.

OpenGL for Embedded Systems (OpenGL ES) is a subset of the OpenGL 3D graphics API designed for embedded devices such as mobile phones, PDA's, and video game consoles. OpenGL ES is managed by the not-for-profit technology consortium, the Khronos Group, Inc.

Current version is OpenGL ES 3.2 (), publicly released in August 2015.

OpenGL ES 2.0
OpenGL ES 2.0 eliminates most of the fixed-function rendering pipeline in favor of a programmable one. Almost all rendering features of the transform and lighting pipelines, such as the specification of materials and light parameters formerly specified by the fixed-function API, are replaced by shaders written by the graphics programmer. As a result, OpenGL ES 2.0 is not backwards compatible with OpenGL ES 1.1.

OpenGL ES 3.0
The latest major version is the OpenGL ES 3.0 specification, publicly released in August 2012. OpenGL ES 3.0 is backwards compatible with OpenGL ES 2.0, enabling applications to incrementally add new visual features to applications.

glVertexAttribPointer and glVertexAttribFormat: What's the difference?

OpenGL 4.3 and OpenGL ES 3.1 added several alternative functions for specifying vertex arrays: glVertexAttribFormat, glBindVertexBuffers, etc. But we already had functions for specifying vertex arrays. Namely glVertexAttribPointer. Why add new APIs…

I'm making an android game and am currently not getting the performance I'd like. I have a game loop in its own thread which updates an object's position. The rendering thread will traverse these objects and draw them. The current behavior is what…

Appropriate multiplication of matrices for rotation/translation

In order to rotate/translate object (rotation only about z-axis and translation only in xy plane) not just w.r.t to global center (device center) but also w.r.t other arbitrary points, I created an algorithm, which is correct (because all senior…

Can I use glu with Android NDK

I can't seem to include glu.h in my Android NDK project. I'm trying to port existing C++ code to NDK, and it uses glu in a few places (notably gluErrorString). Does OpenGLES not have glu? Is there a port I can use? If not I can probably remove the…

OpenGL Texture Coordinates in Pixel Space

I'm working on an iPhone app that uses OpenGL ES 2 for its drawing. I know that typically texture coordinates are defined in the 0-1 range, but ideally I'd like to map them from 0-1023 (the size of my TextureAtlas) for readability's sake. I've seen…
