hi

i am trying to combine the "extrusion" sketch found in the examples folder of processing, with a simple video input.

what i want, basically, is a video input where the brightness of a pixel controls the z factor of its position.

here's my newbie code;

import processing.video.*;
Capture myCapture;

PImage extrude;
int[][] values;
float angle = 0;

void setup()
{
 size(500, 400, P3D);
 myCapture = new Capture(this, width, height, 30);
 
 extrude.loadPixels();
 values = new int[extrude.width][extrude.height];
 for (int y = 0; y < extrude.height; y++) {
   for (int x = 0; x < extrude.width; x++) {
     color pixel = extrude.get(x, y);
     values[x][y] = int(brightness(pixel));
   }
 }
 
}

void captureEvent(Capture myCapture) {
 myCapture.read();
}

void draw() {
 image(myCapture, 0, 0);
 
   for (int y = 0; y < extrude.height; y++) {
   for (int x = 0; x < extrude.width; x++) {
     stroke(values[x][y]);
     point(x, y, -values[x][y]);
   }
 }
 
}

the next step involves sending out the z-values of one particular line to max/msp for a 2dwave oscillator!

hope someone can help me figure out this problem first though... thanks!
