The graphics example of apidemos contains the OpenGL ES example. OpenGL ES is mainly used to develop 3D graphics applications. OpenGL ES (OpenGL for embedded systems) is a subset of OpenGL 3D graphics APIs. It is designed for embedded devices such as mobile phones, PDAs, and game hosts.
The following is an introduction to OpenGL ES in Wikipedia:
OpenGL ES is customized from OpenGL, excluding glbegin/glend, quadrilateral (gl_quads), polygon (gl_polygons) and other complex elements. After years of development, there are now two major versions: OpenGL ES 1.x for fixed pipeline hardware and OpenGL ES 2.x for programmable pipeline hardware. OpenGL ES 1.0 is based on the OpenGL 1.3 specification, and OpenGL ES 1.1 is based on the OpenGL 1.5 specification. They support both common and common lite profiles, respectively. Lite profile only supports fixed-point real numbers, while common profile supports both fixed-point and floating-point numbers. OpenGL ES 2.0 is defined by reference to the OpenGL 2.0 standard. The common profile is released in 2005-8, introducing support for programmable pipelines.
Before parsing the OpenGL ES example in Android apidemos, it is necessary to provide a simple development tutorial for OpenGL ES development, which can help developers who have never been in touch with 3D development.ProgramDevelopers understand the basic concepts and methods of OpenGL development. Many mobile phone platforms provide support for OpenGL ES Development Kits. Therefore, although the Android platform is used to introduce OpenGL ES, however, the basic concepts and steps also apply to other platforms.
For more information about the simple development tutorial, see jayway.
The OpenGL ES development tutorial in team blog is a simple and easy-to-understand development tutorial. It is suitable for beginners of OpenGL ES.
In addition to this concise OpenGL ES development tutorial, We will write a development tutorial specifically for OpenGL ES in the future.
