    Dear all,

     

    Before I’ll port my application to iPone OS, I develop it completely on Windows 7, Visual Studio 2010, PowerVR OGLES2_WINDOWS_PCEMULATION_2.06.26.0649.

     

    Despite I setup necessary parameters to allow my applicaiton display antialiased 3D objects, I can not achieved desired effects:

     

     const EGLint pi32ConfigAttribs[] =
     {
      EGL_LEVEL,    0,
      EGL_SAMPLE_BUFFERS,  1,
      EGL_SAMPLES,   2,
      EGL_BUFFER_SIZE,  0,
      EGL_SURFACE_TYPE,  EGL_WINDOW_BIT,
      EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
      EGL_NATIVE_RENDERABLE, EGL_FALSE,
      EGL_DEPTH_SIZE,   16,
      EGL_NONE
     };

     

    • Can you please confirm that there are no issues with multisampling and Windows Emulator?
    • Can you advice what else to test or try, to get the desired multisampled output? 
    • What additional specifications do you need to better understand the possible cause of the problem?

      • I have:

        • Intel based CPU
        • nVidia GTX 260 graphics.
        • Video driver: nVidia 64Bit, v.258.96
        • nVidia Control Panel: v.2.8.313.10

    • As a test application, I ran the following, but received no change in graphics output at all: “C:Program Files (x86)Imagination TechnologiesPOWERVR SDKOGLES2_WINDOWS_PCEMULATION_2.06.26.0649BinariesTrainingCourseIntroducingPODOGLES2IntroducingPOD.exe” -FSAAMode=4
    • Should I enable multisampling for OpenGL somewhere in the graphics card settings? I did not find anything OpenGL related.

    Thank you,

    Rene
