Is there a way to implement Anitaliasing technique in OpenGL ES 2.0 ? I have goggled and found few methods but there was no change in the output. In the worst case I've planned to implement multiple pass rendering, to smooth the edges in fragment shader, by displaying average colour of the pixels around every pixel, but it costs more GPU performance. Any suggestions ? Reto Koradi A lot of devices support MSAA (Multi-Sample Anti-Aliasing). To take advantage of this feature, you have to choose a EGLConfig that has multisampling. On Android, if you use GLSurfaceView , you will have to implement
