MOVING IMAGE STUDIO I

Day of Color

• PDF of presentation slides
• sketchtext001: grayscale (code)
• sketchtext002: complementary color (code)

To run the code in Processing, you will need the MyGUI library.

In class code:
We seem to have found another bug, this one resolved by moving the colorMode() call to draw().

color frontColor, backColor;
int hueValue, compHueValue; 

void setup() {
  size(500, 500);
  //default:
  // colorMode(RGB, 256);
  // standard format for HSB (degrees):
  colorMode(HSB, 360);
  frameRate(15);

  hueValue = 0;
  compHueValue = hueValue + 180;
  smooth();
}

void draw() {
  colorMode(HSB, 360);
//  println (hueValue + "t" + compHueValue);
 frontColor = color(hueValue, 359, 359);
 backColor = color (compHueValue, 359, 359);
 background(backColor);

 fill(frontColor);
 noStroke();
 ellipse(width/2, height/2, 500, 500);

 hueValue+=1;
 if (hueValue == 360)
  hueValue = 0; 

 compHueValue = hueValue + 180;
 if (compHueValue >= 360)
   compHueValue -= 360;
}
