This thread got me interested in fractals again and I wrote a program to draw the mandelbrot set (NOTE: the squared character doesn't show up here so I did X*X instead, that's just an example though):
Code:
ClrDraw
FnOff
-4.7->Xmin
-3.1->Ymin
4.7->Xmax
3.1->Ymax
0->C
For(A,-2,2,.1
For(B,0,2,.1
0->I
0->X
sqrt(A*A+B*B)->D
A+Bi->E
While D<=2 and I<50 ;<= is less than or equal to
X*X+E->F
Ans->X
sqrt(real(F)*real(F)+imag(F)*imag(F)->D
I+1->I
End
If D<=2
Then
Pt-On(A,B
Pt-On(A,-B
End
C+1->C
Text(54,0,C
End
End
I also wrote one to draw a julia set. This means you enter a complex constant and it will draw a different set every time! I know it doesn't sound that exciting but I've never seen a program that did this on a calc. I wish I knew even simple assembly, I could probably make a great-looking and really fast program.  |

| well, Bryan Thomas and I are currently making one in C. It'll do the mandelbrot and Julia sets and have some other options. This program will be good enough for practice. It just needs a few optimizations. Also, if your going to use greyscale, I'll post a modified basic code that'll show you how to do it. Yes, I know you can't do greyscale in basic but it'll get the general idea across. |

i was just browsing about fractals, and found this little thing here. pretty cool...or, at least it will be when my calc is finished drawing (so far it's not much, but the cod looks interesting, at least)
The only things i found were these:
Quote: Code: -4.7->Xmin
-3.1->Ymin
4.7->Xmax
3.1->Ymax
you can just say ZDecimal
Quote:
Delvar IDelvarX
besides those two things, it's great. thanks! i'd been looking for a fractal program for a while
EDIT: it finished, and was OK, just that it didn't show very much. just 20 pixels or so across. maybe change the window vars?
EDIT AGAIN: is there any way to make this fractal image bigger (filling the entire screen) or faster?
