The 'ETC2' scheme expands ETC1 in a backwards-compatible way to provide higher quality RGB compression, [6] as well as compression of RGBA (RGB plus alpha). The following ETC2 codecs are mandatory in OpenGL ES 3.0 [7] and OpenGL 4.3: [8]
Rendering calculations are outsourced over OpenGL to the GPU to be done in real-time. The DRI regulates access and book-keeping. The Direct Rendering Infrastructure (DRI) is the framework comprising the modern Linux graphics stack which allows unprivileged user-space programs to issue commands to graphics hardware without conflicting with other ...
In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.
OpenGL (Open Graphics Library [4]) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.
OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones ...
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]

Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. [ 1 ] [ 2 ] It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Game Technology Group at Sun Microsystems .
