week 05

 第一節

import processing.video.*;

Movie movie;

void setup(){

  size(640,480);

  movie = new Movie(this, "launch2.mp4");

  movie.loop();

}

void draw(){

  image(movie,0,0);

}

void movieEvent(Movie m){

  m.read();

}

第二堂

因為沒有視訊鏡頭，所以無法撥放影片

import processing.video.*;

Capture cam;

void setup(){

  size(640,480);

  cam = new Capture(this, 640,480);

  cam.start();

}

void draw(){

  if(cam.available()){

    cam.read();

  }

  image(cam,0,0);

}

import processing.video.*;

Capture cam;

void setup(){

  size(640,480);

  cam = new Capture(this, 640,480);

  cam.start();

}

void draw(){

  if(cam.available()){

    cam.read();

  }

  image(cam,0,0);

  saveFrame();

}

第三堂

import processing.video.*;

Movie movie;

void setup(){

  size(640,480);

  movie = new Movie(this, "my_webcam.mov");

  movie.loop();

}

void draw(){

  if(movie.available()){

    movie.read();

  }

  image(movie,0,0);

}

void setup(){

  size(640,480);

  background(255,0,0);

}

void draw(){

  println(frameCount);

}

void mousePressed(){

  loadPixels();

  for(int i=0;i<640*480/2;i++){

    pixels[i]=color(0,255,0);

  }

  updatePixels();

  saveFrame();

}

第四堂

教導使用github

color [] c = {#F0F0F0,#FFF160,#FFC501,#FE9600,#03001C};

int now=0;

void setup(){

  size(640,480);

  background(#F0F0F0);

}

void draw(){

 

}

void mousePressed(){

  background(c[now]);

  now = (now+1)%5;

}

import processing.video.*;

Movie movie;

color [] c = {#F0F0F0,#FFF160,#FFC501,#FE9600,#03001C};

int now=0;

void setup(){

  size(640,480);

  background(#F0F0F0);

  movie = new Movie(this, "my_webcam.mov");

  movie.play();

}

void draw(){

  if(movie.available()){

    movie.read();

    image(movie,0,0);

  }

}

void mousePressed(){

  movie.pause();

  loadPixels();

  for(int i=0;i<640*480;i++){

    float bright = brightness(pixels[i]);

    int now = 4-int(bright/67);

    pixels[i] = c[now];

  }

  updatePixels();

}
