Dear all,

&nbsp;
  

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.
  

&nbsp;
  

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

&nbsp;
  

&nbsp;const EGLint pi32ConfigAttribs[] =  
&nbsp;{  
&nbsp;&nbsp;EGL\_LEVEL,&nbsp;&nbsp;&nbsp;&nbsp;0,  
&nbsp;&nbsp;EGL\_SAMPLE\_BUFFERS,&nbsp;&nbsp;1,   
&nbsp;&nbsp;EGL\_SAMPLES,&nbsp;&nbsp;&nbsp;2,  
&nbsp;&nbsp;EGL\_BUFFER\_SIZE,&nbsp;&nbsp;0,  
&nbsp;&nbsp;EGL\_SURFACE\_TYPE,&nbsp;&nbsp;EGL\_WINDOW\_BIT,  
&nbsp;&nbsp;EGL\_RENDERABLE\_TYPE,&nbsp;EGL\_OPENGL\_ES2\_BIT,  
&nbsp;&nbsp;EGL\_NATIVE\_RENDERABLE,&nbsp;EGL\_FALSE,  
&nbsp;&nbsp;EGL\_DEPTH\_SIZE,&nbsp;&nbsp;&nbsp;16,  
&nbsp;&nbsp;EGL\_NONE  
&nbsp;};
  

&nbsp;
  

  
- 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?&nbsp;  
- 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.
