glFrameBufferTexture2DMultisample on IOS?


#1

Hiya
I’d like to use render to texture with multi sampling on the ipad.
It seems the extension “glFrameBufferTexture2DMultisample” is not supported on the iphone/ipad. Is that the end of the story?
Is there other anyway to achieve the same effect?

cheers,
Nick

Hi nickb - please look at the APPLE_framebuffer_multisample extension and the Apple developer pages:

There may be other solutions in specific cases - our Anti Aliased Lines training course in the OpenGL ES 1.1 SDK has an example of this, but I’d suggest trying the extension first.
