Project 1X

by admin @ 5:23 am September 7, 2011

All projects 1X are due Monday September 12:

  • Project 10: Reading; Looking Outwards
  • Project 11: For loops & randomness
  • Project 12: Embedded iteration wallpaper
  • Project 13: PDF output
  • Project 14: Order/Chaos composition

Project 10: Reading and Viewing

  • In ‘Getting Started with Processing’, read pages 37-48 (Topics: variables, repetition).
  • Spend a half-hour surfing new-media arts links. In a blog post, write 3 ‘Looking Outwards’ assignments about works you have discovered (embed a video or image, write 100-150 words, tag with the ‘LookingOutwards’ category).

Variables, Iteration, Blocks

  • Introduction to variables (Golan’s ten lines example)
  • for loops (ten lines example, generalized)
  • Side note: Scoping of variables with respect to blocks.

Diagnosis

  • Printing the values of variables to the console
  • Constructing simple strings
  • Displaying strings by drawing text

Mouse Interaction

  • Interactions based on continuous cursor data
    • Printing out the mouse values
    • A ball linked to the mouse directly
    • A ball mathematically related to the mouse value
    • A ball linked to the mouse by inverse relationships
  • Introduction to conditional testing. if (mouseX > val)
  • Interactions based on discrete mouse data: if (mousePressed)
  • The mousePressed() method
  • A latch, which calls draw() only after mousePressed().
boolean doIt; 
 
void setup(){
  size(200,200);
  doIt = true;
}
 
void draw(){
  if (doIt){
    background(random(255), random(255), random(255));
    doIt = false;
  }
}
 
void mousePressed(){
  doIt = true;
}

Generating random numbers.

  • applying randomness to different properties: color, position, size.
  • constrained randomness:  e.g. bluish ellipses.

Project 11: A composition with for loops & randomness.

  • Create a composition with 12 randomly generated shapes, using iteration.
  • Bonus: have the shapes relate to each other, by using a persistent variable to store information about the previously generated shape, and then using that variable to somehow generate the next one based on the previous one.
  • Upload to our OpenProcessing classroom.

Project 12: Wallpaper using nested for loops (‘Embedded iteration’)

Project 13: PDF output!

  • Instead of drawing to the screen, we can draw your wallpaper to a (vector based) PDF file.
  • See: http://www.processing.org/reference/libraries/pdf/index.html.
    • Use the techniques described there to produce a PDF version of your wallpaper.
    • I recommend either “Single Frame (With Screen Display)” or “Single Frame from an Animation (With Screen Display)”.
  • Print out your PDF onto an 11×17″ sheet of paper and bring it to class for a pinup crit. Color or B&W, up to you.
  • Embed the PDF in a blog post. We are using the Embed PDF plugin; there’s some documentation there.
  • To embed the PDF in your blog post:
    • Click on the little “Add Media” button in the WordPress editor ( Add Media );
    • Upload your PDF;
    • Be sure to grab the URL of your PDF image (it will look like http://cmuems.com/2011/a/wp-content/uploads/2011/09/blabla.pdf or something);
    • In your blog post, use the PDF embed shortcode, as described here, with your specific PDF’s URL.

 Project 14: Interactively Parameterized Randomness

  • See the helpful functions: map(), constrain()
  • Make a composition which depicts “order” when the mouseX is on the left side of the canvas, and “chaos” when it is on the right side. The degree of order/chaos (entropy) should vary smoothly with the position of the mouse.
  • Upload to our OpenProcessing classroom.
