Hey guys, I have been creating some still 3D images based on Conway's Game of Life using Sunflow.  I'm getting some nice results http://antipasto.union.edu/~goldenbr/codeart/life/main.html , but would like to eventually print them very large (20-30 inches).  Any thoughts on how to achieve a really hi-res image that is quite large? Thanks.

I feel like that might bypass the the Sunflow rayracer.  Is it possible to render out the finished image to a file rather than displaying it on the screen, which restricts the size?  Here is the code if my explanation isn't great.

import hipstersinc.sunflow.*;
import hipstersinc.sunflow.shader.*;
import hipstersinc.*;

int sz = 20;
int zSize = 19;
int zLevel = -350;

int[][] data;
String[] lines;

void setup() {
 
 size(1400,600,"hipstersinc.P5Sunflow");
 background(255);
 noStroke();
 lines = loadStrings("data.txt");
 data = new int[lines.length][lines[0].length()/2+1];
 for(int i=0;i<lines.length;i++){
   int[] temp = int(split(lines[i], ","));
   
   for(int x=0; x<temp.length; x++){
      data[i][x]=temp[x];
   }
 }

 noLoop();

}

void draw(){
 background(255);
 setupCamera();

 
 //camera(-200, -200, 500, width/2, height/2, 100,-1, 1.0, 0.0);
camera(-700,-200, 700,800, 400,300 ,0, 1.0, 0.0);

 
 int[][] life= new int[20][20];
 for(int z = 0; z< 65; z++){
     int xpos = -1;
   for(int a =0; a<data[z].length; a++){
     
     if(a % 20 == 0){
       xpos+=1;
       
     }
     
     life[xpos][a%20] = data[z][a];
     
   }
   
   for(int i=0; i<life[0].length; i++){
     for(int j=0; j<life[0].length; j++){
       fill(30+z*2,z*3,210-z*2);
       
       if(life[i][j]==1){
         
         pushMatrix();
         
         translate(sz * i , sz * j, zLevel);
         box(sz,sz,zSize);
         
         popMatrix();
       }
     }
   }
   zLevel += zSize;
 
 }
 saveFrame("newBig3.tif");
}

void setupCamera() {
 P5Sunflow sunflow = (P5Sunflow) g;
 sunflow.camera.setType(SunflowCamera.PINHOLE);

}

I just tried running your example and I get the following error:

java.lang.NoSuchMethodException: hipstersinc.P5Sunflow.<init>()

Any ideas why? I unzipped p5sunflow into my Sketchbook location, and I can import it via Sketch -> Import Library.

My setup:
Processing 0154
Mac OS X Leopard
Java 1.5.0_16

addywaddy, i also got something like that but it was very misleading - you need a data.txt file in the data dir. must be 0s and 1s, comma separated, and at least 65 lines long (i think the original was 400x65 with a 20x20 grid per layer but...)

it was the same as yours but with different numbers:

size(4500, 3000, "hipstersinc.P5Sunflow");

i didn't need to change the heap size in the end - it gave an error on the console but generated the image anyway 8) this laptop has 1G of memory, 2G of swap btw, 1.8GHz processor. image generation took about 3 minutes (for a single glider).

(although i think if you needed to do it you'd just need to modify the last line in the processing script file, which i guess is platform dependant - i'm on linux and it says

java processing.app.Base

and i'd add those two options i mentioned earlier after the 'java'. but i am guessing!)

it was, i think, Processing 135 (couldn't get opengl working in 148 so i went back) and the newest Sunflow.

(i still think it might be better skipping Processing and doing this in plain old java and the sunflow library directly.

or, dare i say, php and povray!)

Great find Mike. Maybe this is a stupid question, but the fork doesn't look like normal packaged libraries. It looks like the eclipse template. What pieces do you take or how do you make the fork into a Processing library that you can dump into "Documents/Processing/libraries"?
