OpenGl+ellipse
May 7th, 2008, 4:55pm  
Hi,

I've read that ellipse won't smooth in opengl but the posts were quite old. So, I was wondering is there still problems with this as I am unable to get smooth looking ellipses. I though it could be my crappy built in macbook graphics card as I have seen videos on vimeo and they look fine? or is it because they are using gl to draw the ellipse, not sure as I am not that familiar with opengl.

Did you try hint(ENABLE_OPENGL_4X_SMOOTH)?

Make sure your video card is setup to accept commands or processing might crash. Mipmapping can also help, but that's a whole different story.

I've tried using hint and it doesn't help.

You have a macbook?  Best case scenario you have the intel 950 GMA integrated chipset. It doesn't support multi-sampling so you don't have any Anti-aliasing capabilities. The hints should not work for you.

Give your ellipses a stroke.

Problem solved Smiley

Thanks for the help but giving the ellipses a stroke doesn't fix the aliasing problem. It's weird because it only happens on ellipses - other shapes are fine?
