Hi i was trying to achieve a 3d pixel effect from a video modifying a script i made for a capture...
But for the video I keep on getting an "ArrayIndexOutOfBoundsException: 4810" error !!!
Where am I wrong ?

This is the code working with a CAPTURE

1. import processing.video.*;
   
   
   Capture video;
   
   int cellsize = 20;
   int cols, rows; 
   
   void setup() {
     size(640,480,P3D);
     video = new Capture(this,width,height,30); // Load the video
     cols = width/cellsize;              // Calculate # of columns
     rows = height/cellsize;             // Calculate # of rows
   }
   
   void draw() {
     if (video.available()) {
       video.read();
     }
    
     background(0);
    
    
     video.loadPixels();
   
   
     // Begin loop for columns
     for (int i = 0; i < cols; i++ ) {
       // Begin loop for rows
       for (int j = 0; j < rows; j++ ) {
         int x = i*cellsize + cellsize/2; // x position
         int y = j*cellsize + cellsize/2; // y position
         int loc = x + y*width;           // Pixel array location
         color c = video.pixels[loc];       // Grab the color
   
         // Calculate a z position as a function of pixel brightness
         float z = -(800/(float)width) * brightness(video.pixels[loc])- 100.0;
   
         // Translate to the location, set fill and stroke, and draw the rect
         pushMatrix();
        
            rotateY(0.5);
         translate(x,y,z);
   
   
         fill(c);
         noStroke();
         rectMode(CENTER);
         rect(0,0,cellsize,cellsize);
         popMatrix();
   
       }
     }
   }

And that's how I was trying to modify it for a Movie....

1. import processing.video.*;
   
   
   
   Movie video;
   
   
   
   int cellsize = 20; // Dimensions of each cell in the grid
   int cols, rows;   // Number of columns and rows in our system
   
   void setup() {
     size(480,480,P3D);
     video = new Movie(this,"filmato.mov"); // Load the image
     //video = new Capture(this,width,height,30);
     video.loop();
     cols = width/cellsize;                // Calculate # of columns
     rows = height/cellsize;             // Calculate # of rows
   
   try {
   quicktime.QTSession.open();
   } catch (quicktime.QTException qte) {
   qte.printStackTrace();
   }
   }
   
   
   void draw() {
     if (video.available()) {
       video.read();
     }
    
    
     background(0);
     
     video.loadPixels();
    
   
     // Begin loop for columns
     for (int i = 0; i < cols; i++) {
       // Begin loop for rows
       for (int j = 0; j < rows; j++ ) {
         int x = i*cellsize + cellsize/2; // x position
         int y = j*cellsize + cellsize/2; // y position
         int loc = x + y*width;           // Pixel array location
         color c = video.pixels[loc];     // Grab the color
   
         // Calculate a z position as a function of pixel brightness
         float z = -(500/(float)width) * brightness(video.pixels[loc])- 100.0;
   
         // Translate to the location, set fill and stroke, and draw the rect
         pushMatrix();
        
        //
        
            rotateY(0.5);
         translate(x,y,z);
   
   
        // fill(c);
         noStroke();
         rectMode(CENTER);
         rect(0,0,cellsize,cellsize);
         popMatrix();
   
       }
     }
   }

I Get the error "ArrayIndexOutOfBoundsException: 4810" on the line in wich I grab the pixel color...
Could someone help me please...

Thank you all !
