Hi,

I'm having trouble successfully running a sketch which is any bigger than 2700 X 2700 pixels.  

This sketch reads pixels data from an image, and draws a triangle for each pixel based on that pixels RGB values.  Here is an older version to give you an idea of what is going on: http://friendly.verywhere.org/josh/portfolio/colortriangles2.html

Everything is fine until I start to go big.  I was once able to run the sketch at 3000 X 3000 and create a .tiff file.  Now, I can't even create a blank sketch at 3000 X 3000, because I keep getting java.lang.OutOfMemoryError.  I am running on a dual processor G5 with 1GB of RAM.  Is this an issue with the computer or the limitations of Processing?  

My ultimate goal is to create a giant .tiff file which I could print 40" X 40" at 300 DPI.  In theory I could use AIExport, but these are big images that I am reading in (500KB+), and I don't know if Illustrator could handle such a huge file.

Anyone know how I can make this happen?


Code:

size(3000, 3000);
background(255);


PImage d = loadImage("DSC_0013.jpg");

color b;


for(int i=0; i<d.width*d.height; i++){




b = d.pixels[i];

int n=5;

 int x1 = width/2;
 int y1 = int(height/2-(red(b)*n));

 int x2 = int(width/2-(green(b)*n)*cos(PI/6));
 int y2 = int(height/2+(green(b)*n)*sin(PI/6));

 int x3 = int(width/2+(blue(b)*n)*cos(PI/6));
 int y3 = int(height/2+(blue(b)*n)*sin(PI/6));


stroke(red(b),green(b),blue(b),25); 

noFill();
smooth();
triangle(x1,y1,x2,y2,x3,y3);

}
save("dad_alaska2.tiff");
 

I'm dumping out files in excess of 8mb to illustrator using AIExport, so your 500kb should present no problem at all.

Depends on the functionality you require at run-time. AIExport's going to slow down when you start writing, though I can tailor this a little depending on your requirements. simplePS is best on performance, but not functionality.

I find both are necessary
