antialiasing iPhone OpenGLES

I need in antialiasing in iPhone 3G (OpenGL ES1.1), NOT iPhone 3Gs with OpenGL ES.2.0. I've draw 3d model and have next: pixels on the edges of the model look like teeth.

I've try set any filters for texture, but this filters making ONLY texture INSIDE look better.

How can i make good antialising ? May be i should use any smooth for drawing triangles ? If yes, then how it possible in OpenGL ES1.1 ?

thanks.

Solution

  • You can render into a larger FBO and then use that as a texture on a square.

    Have a look at this article for an explanation.
