What would be the best way to draw antialiased circles of various sizes? The circles will look something like this:



The edge thickness can be defined beforehand since it won't change, but the radius of the circle will change fairly often.

Thanks in advance.

With a texture, scaled as needed.

If you need perfectly constant thickness width, I'd go with 2 textures, one black circle behind, and one slightly smaller circle on top.

Ohh... two layered textures. Very clever. I was thinking of doing a triangle fan at first, but I could already tell the performance of that wasn't going to be up to snuff. Your idea will definitely work fine. Thanks!
