Happy Heart's Day to my fellow devs. Written in C++ and SDL.
If you're only interested in the animation, just download the files under
bin-win/*
If you're interested in the heart equation:
r(t) = 2.0 - 2.0 * sin(t) + sin(t) * sqrt(abs(cos(t)) / (sin(t) + 1.4);
where t = teta, 0 to <360 degrees.
Graph it in Polar form.
For questions, just send me a private msg.
