PC Emulation - Multisampling


#1

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

Hi,

Thx for your feedback. Actually there is a problem with Multisampling within Pcemulation from SDK 2.6 . It will be fixed in our very soon to be released SDK 2.7.
