drawing algorithms

Hi, where can I find algorithms for drawing different shapes, I found some to draw spiral and circle, but I need to have more shapes. Can you please recommend any website(s) that helps? thanks,

just more? nothing specific? http://www.acm.org/tog/GraphicsGems/[^]

thanks El Corazon, I don't need any specific shape, for example:
for( int i=0 ; i<200 ; ++i) { theta = 2+Math::PI*float(i)/10; r = Math::Sqrt(theta); x=r*Math::Cos(theta)+400; y=r*Math::Sin(theta)+400; }this algorithm will give me a very beautiful shape. I need more algorithms that would to the same. -

there are many. It is called a polar graph, or polar equation. That particular one is one of the more simple ones. x=r*cos(theta); y=r*sin(theta); is the translation from polar (radius=r, angle=theta) coordinates to Cartesian coordinates. You can make your own and experiment with others from here: http://www.analyzemath.com/polarcoordinates/polarcoordinates.html[^] http://www.analyzemath.com/polarcoordinates/graphing_polar_equations.html[^] I did many polar coordinates on my first computer, including a spider's web. :)

the number of things you can draw with formulas is seriously limited.
Actually, the number of things you can draw with formulas are infinite, but not all of them attractive. In many cases, one formula provides infinite variations, though subtle, and given multiple formulas and methods (like fractals?), the list goes on.... however... that was why I pointed to the graphics gems first, which covers algorithmic drawing in detail.

Thanks for your help, it was very useful. I was wondering if there are more available algorithms that would draw shapes other than polar. like these beautiful ones: http://www.flickr.com/photos/fire_brace/48702455/in/set-72057594133787168/[^] http://www.flickr.com/photos/fire_brace/48723545/in/set-72057594133787168/[^] I know these are mosaics, but I just need algorithms that would draw such things.

check out the formulas behind fractals. There are many self-similar iterative design systems. http://en.wikipedia.org/wiki/Fractal[^] also L-Systems: http://en.wikipedia.org/wiki/L-system[^]

THANK YOU.:rose:
You are welcome. The hardest part is trying to figure out what you are looking for. There are as many shapes as the imagination, and as many methods of getting them. :)
