I never did much with interactivity and animation in Processing before so I decided to incorporate it into this. The user decides when to stop.Try it out here:
Click and hold the mouse and then shake on the canvas to produce Schotter’s effect.
int square_width = 15;
float acceleration = 0.0;
class Square{
float x,y,theta;
float direction;
Square(float a, float b, float t)
{
x = a;
y = b;
theta = t;
direction = 1.0;
}
void change_angle(float t){
theta = t;
}
void change_Xcoord(float i){
x = i;
}
void change_Ycoord(float i){
y = i;
}
void change_direction(float d){
direction = d;
}
}
Square squaresArray[][];
/**
* initialize the default squares
*/
void generate_squares(){
squaresArray = new Square[height/square_width][width/square_width];
for (int y = 0; y < height/square_width; y++) {
for(int x = 0; x < width/square_width; x++){
squaresArray[y][x] = new Square(x*square_width,y*square_width,0);
}
}
}
void setup() {
size(510, 600);
background(255);
frameRate(30);
noFill();
generate_squares();
}
void mouseClicked(){
for (int y = 1; y < squaresArray.length - 1; y++) {
for(int x = 1; x < squaresArray[y].length - 1; x++){
int a = Math.round(random(0,1));
if(a == 0)
a = -1;
squaresArray[y][x].change_direction((float)a);
}
}
}
void draw(){
// refresh screen
background(255);
float should_move; // decides whether we should change Y coord
if(!mousePressed) // if user is dragging
{
acceleration = acceleration/1.1;
should_move = 0.0;
}
else // the user let go
{
acceleration = (mouseX - pmouseX)*0.007;
should_move = 1.0;
}
// loop through to draw squares
for (int y = 1; y < squaresArray.length - 1; y++) {
for(int x = 1; x < squaresArray[y].length - 1; x++){
Square square = squaresArray[y][x];
pushMatrix();
// rotate the square by theta
translate((int)square.x,
(int)square.y);
rotate(square.theta);
// record new angle
square.change_angle(square.theta +
acceleration*(y/height + 1)*
(y*random(0.0,0.05) *
square.direction));
// record new y location (squares slowly shift downward)
square.change_Ycoord(square.y +
abs(acceleration)*
should_move*
((y*y)/100.0));
// draw the rectangle
rect(0,0,square_width,square_width);
popMatrix();
}
}
}
But actually not sure who would wear this. Maybe put it on your dog and whenever it seems interested in something, indiscreetly make the light go on from afar, and pretend it facilitates interaction with people.
