Pretty fast Mandelbrot set generator...

Post by Bean » Mon Apr 23, 2018 5:14 pm

I wrote a program a play with the Mandelbrot set.
Uses ASM to draw the set and BASIC to handle the user interface.
Takes about 85 seconds in slow mode (NTSC) or about 16 seconds in fast mode.

Comments welcome...

I noticed if you zoom in too much it just goes blank. I think the increment goes to zero.
I am using 8.8 fixed point math in the asm. I guess I could use 4.12 and get more zoom.

I have updated the mandelbrot drawing program.
I now use 4.12 fixed point math so you can zoom in further.
I also added a couple more features (print, set max depth, etc).

I think this is quite a good demonstration program for the good ol' zeddy.
