OpenGL for Qt

OpenGL for qt-x11-opensource-src.

• You have to install mesa, which is open source OpenGL library in Linux. Follow this thread: http://www.larsen-b.com/Article/231.html
• When you configure your Qt-X11, you would see a text info like : "OpenGL support .... yes (Desktop)"
  

OpenGL for qt-embedded-linux-opensource-src

• Embedded Qt doesn't support full OpenGL, instead, it supports OpenGL ES (OpenGL for embedded system), a subset of full OpenGL with a smaller, more constrained API. The most important to OpenGL ES is its header file (API) and specification, you can find them at www.khronos.org. There exist various opensource libraries implementing OpenGL ES. You can find more opensource implementations at http://www.khronos.org/developers/resources/opengles/.

OpegGL for Qtopia

• Starting with the 4.2 release, Qtopia Core supports OpenGL ES (OpenGL for Embedded Systems). To be able to use the OpenGL API in Qtopia Core, it must be integrated with the Q Window System (QWS). This is done by providing an EGL implementation, i.e., a native platform window system interface.
