hey all

aabout 2 yrs ago, i found a sketch online called 3dgreen, which made 3d scan lines based on dark and light/height displacement. i lost the sketch somehow, does anyone have it? i know, i can make it myself, but i really just need it to snap a quick pic for a meeting tomorrow

thanks!

hmm not sure if that is what you are looking for, but i quickly sketched something.

import peasy.*;

boolean record;
PeasyCam cam;

PImage img ;

int meshSize = 5;
int resX = 100;
int resY = 100;
float[][] val = new float[resX][resY];

void setup() {
size(900,600,P3D);
smooth();
background(255);
img = loadImage("heightmap.gif");

cam = new PeasyCam(this, 0,0,0,600);
}

void draw() {

translate(-resX/2*meshSize,-resY/2*meshSize);

for(int x =0; x<resX; x++) {
    for(int y =0; y<resY; y++) {
      val[x][y] = brightness(img.get(x,y))*mouseX/width;
    }
}

background(0);
if (record) {
    beginRaw("unlekker.data.STL",millis()+".stl");
}
noFill();
stroke(0,255,0);
for(int x =0; x<resX-1; x++) {

    for(int y =0; y<resY-1; y++) {
      beginShape(LINES);

      vertex(x*meshSize,y*meshSize,val[x][y] );
      vertex((x+1)*meshSize,y*meshSize,val[x+1][y] );
      vertex((x+1)*meshSize,(y+1)*meshSize,val[x+1][y+1] );
      vertex(x*meshSize,(y+1)*meshSize,val[x][y+1] );

      endShape( );
    }
}

}
