How are circles drawn? (source link pls)

[loveme]

Hi! I was wondering how circles, lines etc. are drawn in Love, but I can't find it in the source. Could someone who knows where to find it post a link, please? Also, if someone knows, I'd like to know what these algorithms are called.
Thanks a bunch!

love.graphics.circle('fill', 10, 10, 100)

No idea how it does it internally though.

Maybe my question wasn't clear enough. I was wondering how it works under the hood.

Thank you for the link!

Well, I guess I still don't know how it works.

It constructs a list of vertices, then extrudes them sideways to make a polygon that's shaped like a polyline, and then renders it normally.

The actual code you want is at:

https://bitbucket.org/rude/love/src/10f ... s.cpp-1404

so raidho is right, it constructs a polygon, which then gets sent to the GPU as vertex data. The actual numbers just comes from the plain-jane cos/sin method: if you don't understand how this works, this wikipedia link might help:
