Hello,  
  
I’m currently using PowerVR emulation software for OpenGL ES 2.0. While observing lot’s of aliasing in the rendering window, I tried to activate multisampling using following configuration for EGL :  
EGL\_LEVEL, 0,  
EGL\_NATIVE\_RENDERABLE, 0,  
EGL\_BUFFER\_SIZE, 0,  
EGL\_DEPTH\_SIZE, 16,  
EGL\_SURFACE\_TYPE, EGL\_WINDOW\_BIT,  
EGL\_RENDERABLE\_TYPE, EGL\_OPENGL\_ES2\_BIT ,   
EGL\_SAMPLE\_BUFFERS, 1,   
EGL\_SAMPLES,2, /\* or even 4 \*/  
EGL\_NONE  
  
But i was’nt able to observe any change in the rendering window. Am I missing something ? Is antialiasing supported in the emulation software ?

Hi,

I'm sorry for a delay in answering. Antialiasing is supported in Pc emulation.

Do you have multisampling working in normal desktop openGL ? What is configuration (operating system, GPU etc., what SDK version are you using) ? I would like you to run some training course from our SDK eg. IntroducingPOD but from commandline. There should be an argument passed to commandline:Â -FSAAMode=2 Â Â , and tell me if this triggers FSAA for you? Â

Thanks for your answer. The problem was that the textures were not filtered using GL\_LINEAR, producing nasty effects on the screen.&nbsp;
