    Hi,

    currently I’m trying to get some code to work on my Ubuntu Linux PC, using the OpenGL ES 1.1 framework (latest version from August 08). I had a look at the PVRShell to get an idea how offscreen rendering should work out. I wanted to create a pixmap and a pixmap surface, thus I created a native X11 pixmap and directed it to eglCreatePixmapSurface.

    eglCreatePixmapSurface(eglDisplay, eglConfig, (NativePixmapType)x11pixmap, NULL);

    First I tried this within my application, which did not work (returning EGL_NO_SURFACE). Then I thought I should test it internally within the PVRShell files, simply setting  m_pShell->m_pShellData->bNeedPixmap to true (everywhere needed). Unfortunately this does not work either (same error, although I did not change anything about the visual depth, etc.), so I suppose that there is something wrong, either with the SDK or with my configuration. Note that everything seems to work if I’m using a window surface. Attached I have some snippets from my Xorg.log file describing my X configuration.

    Any Ideas?

    Regards

    Clemens

    Our OpenGL ES PC Emulation libraries currently don’t support EGL pixmap surfaces. This may change in future releases.

    Hi,

    well, then I have stick to a different solution.

    Thanks anyway,

    Hi,

    Is the emulation of Pixmap Surfaces supported as of now? I am unable to get them working under OpenGLES 1.1 emulator.

    If not, can you suggest how I could emulate the offscreen rendering like pixmap or pbuffer?

    Thanks
    Mohan

    Pixmap Surfaces have not been implemented yet (it’s fairly complicated apparently). They are on the roadmap, but I can’t say when it will definitely be available

    Are pixmaps supported in the current version of Win32 SDK (PVRVFrame_2.06.26.0683)?

    Pixmaps (in terms of rendering to pixmaps) are not supported at that version.  And in general pixmaps are not yet supported.
