i edited BronzeWing's code and made it faster so it still has a cool update effect(as long as line 72 is not commeted). it's faster than Aristotle's code when line 72 is commeted out and almost as fast when its not commeted out
#!/usr/bin/perl -w use strict; use Tk; ############ # Settings # ############ my $Epsilon = 8; my @Lines = ([200, 300, 600, 300]); my @Points = map $_/90, ( #my design best with 90 for @Points (-20,20), (20,10), (90,-10), (120,20), #original design best with 96 for @Points #( 0, 0), #( 10, 20), #( 90, -20), #(100, 0), ); #you can put your own colors here sub randomc { my $i = rand(2); if ($i>=0 && $i<1) {return '#b10000';} if ($i>=1 && $i<2) {return '#b15128';} } ########### # Widgets # ########### my $Main = new Tk::MainWindow; $Main->Label('-textvariable'=>\(my $Status="Initializing..."))->pack; my $Canvas = $Main->Canvas( '-width'=>900, '-height'=>700, '-background'=>'#000000' )->pack; my @LineItems = @Lines; ############# # Main Loop # ############# $Main->update; while (++our $i<10) { # change 10 if u need more $Status = "Iteration $i..."; for (my $Line=0;$Line<=@Lines-1;$Line++) { my @Line = @{$Lines[$Line]}; if (abs($Line[2]-$Line[0])>$Epsilon or abs($Line[3]-$Line[1])> +$Epsilon) { my @NewLines; my @NewItems; for (my $Point=0;$Point<$#Points-1;$Point+=2) { my ($X1, $Y1, $X2, $Y2) = @Line; push @NewLines, my $NewLine = [ $Line[0]+($Line[2]-$Line[0])*$Points[$Point+0] + ($Line[3]-$Line[1])*$Points[$Point+1], $Line[1]+($Line[3]-$Line[1])*$Points[$Point+0] - ($Line[2]-$Line[0])*$Points[$Point+1], $Line[0]+($Line[2]-$Line[0])*$Points[$Point+2] + ($Line[3]-$Line[1])*$Points[$Point+3], $Line[1]+($Line[3]-$Line[1])*$Points[$Point+2] - ($Line[2]-$Line[0])*$Points[$Point+3] ]; push @NewItems, $Canvas->createLine(@$NewLine, '-fill' + => randomc()); } splice(@Lines,$Line,1,@NewLines); #$Line += $#NewLines;#good for some fractals not for others wi +thout commet you need more iterations and update effect isnt as good } $Main->Exists ? $Main->update : exit; #with this line commeted + out its like Aristotle's Code } $Main->Exists ? $Main->update : exit; last unless 2; } $Status = "Done."; MainLoop;
