I'm a french student working on the different means to draw a circle. I would like to know the name of the algorithm that Photoshop uses to draw circles.

Thanks for answering and reading my poor english.

I'm just looking for some algorithms as example : I've found some theoric methods, but I would like to know what is really used in applications like Photoshop.

You would be better off looking in a computer graphics textbook.

Photoshop has multiple algorithms for circles/ellipses depending on what you're doing, and the algorithms are not that simple (especially when they need antialiasing).
