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.
