OpenGL ES on AM3517 with Linux and without X11

Other Parts Discussed in Thread: AM3517

 Hello,

    We are thinking to develop a graphical fullscreen application using the AM3517 microprocessor and we wondered if it possible to develop it using the OpenGL ES API on Linux but without X11 system. It is possible to make this and also take advantage of the graphical hardware processor?

 

Thank you,

    Juan

    That is possible, depends on your project. You can find the source code of framebuffer version of the demos/trainingcourses in the gfx SDK.

    But if your project has fancy 2D UI, you may want to think about Qt/E to speed up your developement.

    Ok, thank you I though if you use the framebuffer you couldn't access to the hardware acceleration through OpenGL. Could you tell me where I can download these demos/trainingcourses?

     

    Thanks

    you can get the demos and training courses in the Graphics SDK 3_01_00_06 package in the http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/AM3517/latest/index_FDS.html

    Juan,

       Without a windowing system (such as X11 or Qt) your OpenGL ES application must run in full-screen mode.  We call this a "Null" windowing system and this is how the demos in the PowerVR Graphics SDK run.  It works very well.  You could use OpenGL ES to simulate "windows" within the full-screen window or you can use the QGLWidget class to run OpenGL ES within the Qt windowing system.
