The Embedded Systems 3D Game Software Development Kit, short ES 3D Game SDK, is an Open Source 3D Game Engine / SDK for embedded devices / mobile phones. The ES 3D Game SDK uses the OpenGL ES standard for rendering its content. The SDK is written in ANSI C/C++ and uses almost, besides the OpenGL ES library, only ANSI C libraries. On Symbian devices, the Open C library can be used as well. Target platforms are mobile phones (e.g. Symbian S60 devices like the Nokia N93 or N95), Personal Digital Assistants (e.g. Pocket PC devices). As OpenGL ES is available for many platforms, the SDK runs on other machines as well (e.g. Windows) and cross platform development can be done.
