Either WPF or System.Drawing with System.Windows.Forms could work for you. I would suggest you use a bitmap for rendering. This way, you can have a tree of already calculated regions on a complex plain, and you can derive new region from any of the already rendered regions using mouse selection.

I only would warn you against using SetPixel. Even though calculations are pretty slow, too…

Wind System.Drawing, you should use the technique based on LockBits:

With WPF, you would use System.Windows.Media.Imaging.WriteableBitmap:
http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.writeablebitmap.aspx[^].

Both MSDN pages have some code samples showing how to work without SetPixel

Solution 1

Have a look at this: Mandelbrot Set for C#[^] it just uses SetPixel, which is part of System.Drawing

Would be too slow due SetPixel, maybe even noticeable compared to calculations...
