Julia sets - fractals

[MysticAngel]

this a really good and a neat program. i did ran into a some trouble and coudnt figure out the problem, but i did it.its fun. u care to run it u would find it pretty fun and the fractals are beautiful. the higher the maxcount the bettter the picture and u can also play around with the count + 55. u canchange to any color by saying count + something. anyways enjoy.

code:

var p, q : real var maxcount, count : int var win1, win2 : int var rx, ry, rx2, ry2 : real var col : string put "Please enter a value for p " get p put " " put "Please enter a value for q" get q put "" loop     put "please enter max count between 20 and 200 "     get maxcount     exit when maxcount >= 20 and maxcount <= 200     put "Enter thye maxcount only between 20 to 200 " end loop win2 := Window.Open ("graphics:800;700,position:150;150,nocursor") for x : 0 .. maxx     for y : 0 .. maxy         rx := 3.5 / maxx * x - 1.75         ry := 3.5 / maxy * y - 1.75         count := 1         loop             rx2 := rx * rx - ry * ry + p             ry2 := 2 * rx * ry + q             rx := rx2             ry := ry2             exit when rx * rx + ry * ry > 4| count = maxcount             count := count + 1         end loop         if count < maxcount then             Draw.Dot (x, y, count + 55)         else             Draw.Dot (x, y, white)         end if     end for end for

MOD Edit: I'm impressed... Mostly with the fact that you stuck to your goals and accompleshed them. Sorry we couldn't help you that much with it Also, if anyone comes up with some interesting results, post the numbers used +15Bits - Tony

im glad u figured out ur prob, sorry i didnt post in time(doesnt matter now), heres my prog:

note: to change the res, just change the window size

code:

View.Set ("graphics:150;150,nobuttonbar,position:300;300") proc ColorAdd (c1, c2, n : int)     var clr : int     var r1, g1, b1 : real     var r2, g2, b2 : real     var p, p0 : real     RGB.GetColor (c1, r1, g1, b1)     RGB.GetColor (c2, r2, g2, b2)     const a := 50     for i : 1 .. n         p := (i / n) * 100         p0 := 100 - p         clr := RGB.AddColor ((((r1 * p) + (r2 * p0)) / 2) / a, (((g1 * p) + (g2 * p0)) / 2) / a, (((b1 * p) + (b2 * p0)) / 2) / a)     end for end ColorAdd ColorAdd (yellow, blue, 25) function distance (x1, y1, x2, y2 : real) : real     result ((x1 - x2) ** 2 + (y1 - y2) ** 2) ** 0.5 end distance var ox, oy : real := maxx div 2 type complex :     record         r : real         i : real     end record function AddComplex (comp1, comp2 : complex) : complex     var hold : complex     hold.r := comp1.r + comp2.r     hold.i := comp1.i + comp2.i     result hold end AddComplex function MultComplex (comp1, comp2 : complex) : complex     var hold : complex     hold.r := (comp1.r * comp2.r) - (comp1.i * comp2.i)     hold.i := (comp1.r * comp2.i) + (comp1.i * comp2.r)     result hold end MultComplex function Iterate (comp1 : complex, C : complex) : complex     var hold : complex     hold := MultComplex (comp1, comp1)     hold := AddComplex (hold, C)     result hold end Iterate const maxI := 75 var count : int := 0 var dwell : array 0 .. maxx * 3, 0 .. maxy * 3 of real var transX, transY : int := maxx div 2 var c : complex c.r := -0.79 c.i := 0.16 var hold : complex put "Rendering..." for x : -transX .. maxx     for y : -transY .. maxy         hold.r := x / (maxx div 2)         hold.i := y / (maxy div 2)         loop             count += 1             exit when count >= maxI             if distance (hold.r, hold.i, ox, oy) <= maxx div 1.3 then                 hold := Iterate (hold, c)             else                 exit             end if         end loop         dwell (x + maxx, y + maxy) := count         drawdot ((x + transX) div 1, (y + transY) div 1, 255 + round ((dwell (x + maxx, y + maxy) / maxI) * 25))         count := 0     end for end for

MOD Edit: Catalyst with his madd skillz +15Bits -Tony

wow, like way out man....

[MysticAngel]

put p as -1, q as 0 and the maxcount as 97
shold give u pretty result

[octopi]

p=0
q=1
maxcount=50


gives a cool lightning bolt effect.

[MysticAngel]

That's pretty cool
