Anti Aliasing FBO in OpenGL ES

Hi all,

I’m developing an iOS application in which I want to draw an ofMesh. When I draw it directly to the screen, edges are anti aliased finely. But when it is drawn in to an fbo it gets aliased. Can’t increase numSamples of the fbo as MSAA is not supported in OpenGL ES. I tried supersampling as suggested in other discussions here, but the problem is iPad only supports maximum fbo size of 4096X4096. So I can only get 2X smoothing (iPad display resolution is 1536X2048) which is not enough. I also tried an FxAA shader available at but it also didn’t much improve the quality.

Any solutions or work around for this problem?
