[email protected] embeddedact.com Android includes support for high performance 2D and 3D graphics with the Open Graphics Library (OpenGL®), specifically, the OpenGL ES API. OpenGL is a cross-platform graphics API that specifies a standard software interface for 3D graphics processing hardware. OpenGL ES is a flavor of the OpenGL specification intended for embedded devices. Android supports several versions of the OpenGL ES API: • OpenGL ES 1.0 and 1.1 - This API specification is supported by Android 1.0 and higher. • OpenGL ES 2.0 - This API specification is supported by Android 2.2 (API level 8) and higher. • OpenGL ES 3.0 - This API specification is supported by Android 4.3 (API level 18) and higher. • OpenGL ES 3.1 - This API specification is supported by Android 5.0 (API level 21) and higher. Android supports OpenGL both through its framework API and the Native Development Kit (NDK). This topic focuses on the Android framework interfaces. For more information about the NDK, see the Android NDK. This program is towards how to develop mobile graphics using OpenGL ES for Android. 1. Introduction to 3-D Graphics 1.1.
