!FracZoom released

I spent some time turning my Mandelbrot benchmark in a small Mandelbrot exploration zoomer. You can find the software here !FracZoom

After hopefully digging out all the errors it should run without any problems on the Panda and Beagle. Initially you can zoom in at a frame rate of 12 to 25 Frames/s, depending your board.

The zooming is done with the mouse, left in, right out, depending on the location where you put the pointer…other options are there in the menu. It’s single task, you can edit the screen resolution easily in the !RunImage. Out of the box it’s 1024×768. Run’s also at up to 1920×1200. Of course lot’s of stuff is missing, like double precision support, decent colour palettes, colour cycling, etc. That might come up in time…

Thanks to NEON and the boundary tracing algo one can see how fast stuff like that can be on ARM/Risc OS. Any comments welcome.

I have just played a little with FracZoom. Very nice! I remember the times when I had done some Apfelmännchen at the C64. It tooks hours for just one picture.

Please keep on improving it. Double precision is needed next I think. Since it gets really pixelated (and slower ;-) when you go deeper inside the Mandelbrot.
