OpenGL ES 1.X - for Fixed Function Hardware

OpenGL ES 1.1 and OpenGL ES 1.1 Extension Pack

For fixed function hardware: OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and emphasizes hardware acceleration of the API, but is fully backwards compatible with 1.0. It provides enhanced functionality, improved image quality and optimizations to increase performance while reducing memory bandwidth usage to save power. The OpenGL ES 1.1 Extension Pack is a collection of optional extensions added to OpenGL ES 1.1 that reduced variability and bring significant improvements in image quality and performance.

OpenGL ES 1.1.12 Full Specification (.PDF, April 24, 2008). This document provides a self-contained definition of OpenGL ES 1.1. It is recommended for readers who are unfamiliar with desktop OpenGL 1.5.

OpenGL ES 1.1.12 Difference Specification (.PDF, April 24, 2008). This document defines OpenGL ES 1.1 by providing an annotated list of differences relative to the desktop OpenGL 1.5 specification . It is considerably shorter than the Full Specification, and so is recommended for readers who already have a good understanding of desktop OpenGL. The technical content of the two documents is intended to be identical.

OpenGL ES 2.X - for Programmable Hardware

For programmable hardware: OpenGL ES 2.0 is defined relative to the OpenGL 2.0 specification and emphasizes a programmable 3D graphics pipeline with the ability to create shader and program objects and the ability to write vertex and fragment shaders in the OpenGL ES Shading Language. OpenGL ES 2.0 does not support the fixed function transformation and fragment pipeline of OpenGL ES 1.x. Learn More...

OpenGL ES-SC for Safety Critical

OpenGL SC 1.0

For Safety Critial applications: OpenGL ES-SC 1.0 is defined relative to the OpenGL 1.3 specification and is designed to meet the needs of the safety critical market in Avionics, Industrial, Military and Automotive applications including D0178-B certification. Learn More...

OpenGL SC 1.0 at a glance

The Safety Critical Profile for OpenGL is defined to meet the unique requirements of the for safety-critical applications such as avionics and automotive instrumentation displays. OpenGL SC 1.0 removes functionality from OpenGL ES 1.0 to minimize implementation and safety certification costs. It also adds functionality, such as display lists, that are required to support legacy and auto-generated display applications in safety critical markets.

For Safety Critical applications: OpenGL SC 1.0 is defined relative to the OpenGL 1.3 specification and is designed to meet the needs of the safety critical market in Avionics, Industrial, Military and Automotive applications including D0178-B certification.
