Hello,

I hope someone can help me. The problem that i have is that i have to use P3D for a library that i use. But i also want to make a simple drawing tool, where i can draw rectangles and ellipse on top of a image. Can someone help me with this?

Thank you!

Hello,

I have started a few topics about my warp/drawing tool.
Now i know that its not possible to combine my code but i am wondering is it possible to start the next code on a keypressed or something?

These are the codes:

1. //draw
   import processing.video.*;
   import deadpixel.keystone.*;
   Movie mov;
   PGraphics topLayer;
   
   void setup()
   {
     size(displayWidth, displayHeight);
     background(0);
     frameRate(30);
     mov = new Movie(this, "animatie.mov");
     mov.loop();
     topLayer = createGraphics(width, height, g.getClass().getName());
   }
   
   
   void movieEvent(Movie myMovie)
   {
     mov.read();
   }
   
   void draw()
   {
     image(mov, 0, 0);
     topLayer.beginDraw();
     topLayer.fill(1);
     topLayer.ellipse( pmouseX, pmouseY, 50, 50 );
     topLayer.endDraw();
     image( topLayer, 0, 0 );
   }
   
   void keyPressed() {
     switch(key) {
     case 's':
       topLayer.save(" mask.png" );
       break;
     }
   }
   
   

1. import deadpixel.keystone.*;
   import processing.video.*;
   Keystone ks;
   CornerPinSurface surface;
   PGraphics offscreen;
   Movie mov;
   PImage img;
   
   void setup() {
     size(displayWidth, displayHeight, P3D);
     ks = new Keystone(this);
     surface = ks.createCornerPinSurface( 1102, 620, 10);
     offscreen = createGraphics(1102, 620, P3D);
     mov = new Movie(this, "animatie.mov");
     mov.loop();
     img = loadImage(" 2.png");
   }
   void movieEvent(Movie movie) {
     mov.read();
   }
   
   void draw() {
   
     PVector surfaceMouse = surface.getTransformedMouse();
     offscreen.background(128);
     offscreen.beginDraw();
     offscreen.image(mov, 0, 0);
     offscreen.image(img, 0, 0); 
     offscreen.endDraw();
     surface.render(offscreen);
   }
   

Hello,

I hope someone can help me.

I want to make a mask tool for on a movie, first i draw on a movie then save that as a png and then load that in a keystone.

I have the code but i get a error:  The pixels array is null.

This is the code:

import deadpixel.keystone.*;
import processing.video.*;
Keystone ks;
CornerPinSurface surface;
PGraphics offscreen;
Movie mov;
  boolean a = false;
  PImage mask;
PGraphics topLayer;
void setup() {
  // Keystone will only work with P3D or OPENGL renderers,
  // since it relies on texture mapping to deform
  size(800, 600, P3D);
  ks = new Keystone(this);
  surface = ks.createCornerPinSurface( 550, 400,10);
  mask = loadImage("mask.png");
  // We need an offscreen buffer to draw the surface we
  // want projected
  // note that we're matching the resolution of the
  // CornerPinSurface.
  // (The offscreen buffer can be P2D or P3D)
  offscreen = createGraphics(550, 400, P2D);
   topLayer = createGraphics(width, height, g.getClass().getName());
   mov = new Movie(this, "animatie.mov");
  mov.loop();

 
}
void movieEvent(Movie movie) {
  mov.read(); 
}

void draw() {

  // Convert the mouse coordinate into surface coordinates
  // this will allow you to use mouse events inside the
  // surface from your screen.
  PVector surfaceMouse = surface.getTransformedMouse();
 
    image(mov, 0,0, width, height);
  topLayer.beginDraw();
  topLayer.fill(1);
  topLayer.ellipse( pmouseX, pmouseY, 50, 50 );
  topLayer.endDraw();
  image( topLayer, 0, 0 );
 
if (a) {
  // Draw the scene, offscreen
  background(0);
  offscreen.beginDraw();
  offscreen. image(mov,0,0);
  offscreen.endDraw();
  image(mask,0,0);
}
 

  // most likely, you'll want a black background to minimize
  // bleeding around your projection area
  background(0);
 
  // render the scene, transformed using the corner pin surface
  surface.render(offscreen);
}

void keyPressed() {
  switch(key) {
  case 'c':
    // enter/leave calibration mode, where surfaces can be warped
    // and moved
    ks.toggleCalibration();
    break;

  case 'l':
    // loads the saved layout
    ks.load();
    break;

  case 's':
    // saves the layout
    ks.save();
    break;
  
     case 'a':
    // saves the layout
  topLayer.save(" mask.png" );
    break;
 
   case 'q':
    // saves the layout
  a = true;
    break;
  }
