A Mandelbrot generator for Nintendo DS.

User guide

The program starts showing a small area around the origin: from (-2.5,-1.5) to (+1.5,+1.5)... this gives the first image.

Limitations

It does not feature a superscalar quadcore 2GHz+ processor. It only has a 67 MHz ARM946E, which also has no floating point unit at all, so each operation on floating point variables doesn't turn into a single (co)processor opcode, but into a series of integer operation.

So, to keep the image generation time acceptable, the number of maximum iterations of the aforementioned algorithm (actually to a very small value: 32)is limited. It is opt for single precision floating point variables, the fastest choice available.

Controls

Stylus (Tap) - Start recalculating a new image

Stylus (Tap x2) - Zoom in 2x

Stylus (Tap x5) - The second image

L/R - Zoom out

Start - Reset the program to the initial setting
