Hello, Got problems with a code i've copied (
I want to experiment with image extrusion, but can't seem to get it working.
-->problem: arrayindexoutofboundexception: 1024. So there is something wrong with my values...
But what? Can someone help me please?
import processing.opengl.*; PImage img; int[][] values; float angle; void setup() { size(1024, 768, OPENGL); noFill(); values = new int[width][height]; // Extract the brightness of each pixel in the image // and store in the "values" array img = loadImage("nasa-iceberg.jpg"); img.loadPixels(); for (int i = 0; i < img.height; i++) { for (int j = 0; j < img.width; j++) { color pixel = img.pixels[i*img.width + j]; values[j][i] = int(brightness(pixel)); } } } void draw() { background(0); // Set black background translate(width/2, height/2, 0); // Move to the center scale(4.0); // Scale to 400% // Update the angle angle += 0.005; rotateY(angle); // Display the image mass for (int i = 0; i < img.height; i += 2) { for (int j = 0; j < img.width; j += 2) { stroke(values[j][i], 153); float x1 = j-img.width/2; float y1 = i-img.height/2; float z1 = -values[j][i]/2; float x2 = j-img.width/2; float y2 = i-img.height/2; float z2 = -values[j][i]/2-4; line(x1, y1, z1, x2, y2, z2); } } }
