Hello,
I'm working on the installation with shadows, but my practical skills in coding are not that good to bring my project to life.. I really need your help guys.
Basically, what I need is somehow on a border, where black pixels change to white and another way round, suppose to appear a growing element (I draw it in Flash, so it has a quick time format).
For a base I've taken a code from a library called BrightnessTresholding, however, the thing growths everywhere at the place of white pixels.
Thanks a lot!
P.S. This is what I've got so far:
import processing.video.*;
color black = color(0);
color white = color(255);
int numPixels;
Capture video;
Movie myMovie;
void setup() {
size(640, 480); // Change size to 320 x 240 if too slow at 640 x 480
strokeWeight(5);
// Uses the default video input, see the reference if this causes an error
video = new Capture(this, width, height, 24);
numPixels = video.width * video.height;
noCursor();
smooth();
myMovie = new Movie(this, "growingt.mov");
}
void draw() {
background(255);
if (video.available()) {
video.read();
video.loadPixels();
int threshold = 127; // Set the threshold value
float pixelBrightness; // Declare variable to store a pixel's color
// Turn each pixel in the video frame black or white depending on its brightness
for (int y = 0; y < video.height; y = y + 10)
{
for (int x = 0; x < video.width; x = x + 10){
int location = x+(y*video.width);
pixelBrightness = brightness(video.pixels[location]);
if (pixelBrightness > 127) { // If the pixel is brighter than the
// any visualisations go here
image(myMovie, random(x-5, x+5), random(y-5, y+5 ));
// strokeWeight(.5);
// ellipse( random(x-5, x+5), random(y-5, y+5 ), 2, 2);
}
}
}
}
}
