Lezione introduttiva sulla utilizzazione del linguaggio e ambiente Processing per l'insegnamento dell'elaborazione di media e dell'interaction design.

Introduzione

Questa introduzione è basata sul tutorial di Daniel Shiffman .

Processing è un linguaggio ed un ambiente di sviluppo orientato all' interaction design . Nel corso Elaborazione di Media in Processing , Processing è uno degli strumenti principali utilizzati per introdurre elementi di elaborazionedi suoni e immagini. Processing è una estensione di Java che supporta molte delle strutture Java con una sintassisemplificata.

Processing può essere utilizzato in tre:

    Modi di programmazione

  • Basic

    Sequenza di comandi per il disegno di primitive grafiche --
    applet senza naso size(256,256); background(0);stroke(255); ellipseMode(CORNER);ellipse(72,100,110,130); triangle(88,100,168,100,128,50);stroke(140); strokeWeight(4);line(96,150,112,150); line(150,150,166,150);line(120,200,136,200);
  • Intermediate

    Programmazione procedurale --
    applet con naso void setup() { size(256,256);background(0); }void draw() {stroke(255); strokeWeight(1);ellipseMode(CORNER); ellipse(72,100,110,130);triangle(88,100,168,100,128,50); stroke(140);beginShape(TRIANGLES); vertex(114, 180);vertex(mouseX, mouseY); vertex(140, 180);endShape(); strokeWeight(4);line(96,150,112,150); line(150,150,166,150);line(120,200,136,200); }
  • Complex

    Programmazione Orientata agli Oggetti (Java) --
    applet con naso colorato Puppet pinocchio;void setup() { size(256,256);background(0); color tempcolor = color(255,0,0);pinocchio = new Puppet(tempcolor); }void draw() { background(0);pinocchio.draw(); }class Puppet { color colore;Puppet(color c_) { colore = c_;} void draw () {stroke(255); strokeWeight(1);ellipseMode(CORNER); ellipse(72,100,110,130);stroke(colore); beginShape(TRIANGLES);vertex(114, 180); vertex(mouseX, mouseY);vertex(140, 180); endShape();strokeWeight(4); line(96,150,112,150);line(150,150,166,150); }}

I programmi Processing possono essere convertiti in applet Java. Per fare ciò è sufficiente andare nel menu File e scegliere Export . Il risultato finale sarà dunque la creazione di cinque file, inseriti nel folder applet :

  • Index.html

    sorgente html per visualizzare la applet
  • Filename.jar

    la applet compilata, completa di tutti i dati (immagini, suoni, ecc.)necessari
  • Filename.pde

    il codice sorgente Processing
  • Filename.java

    il codice Java che incorpora il codice sorgente Processing
  • Loading.gif

    un'immagine che viene mostrata mentre si attende il caricamento della applet.
Inoltre, mediante Export Application è possibile generare una applicazione eseguibile per piattaformaLinux, MacOS, o Windows.

Tipi di dati

Variabili

Una variabile è un puntatore a una locazione di memoria, e può riferirsi a valoriprimitivi ( int , float , ecc.) oppure ad oggetti o array (tabelle di elementi di un tipo primitivo).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
