processing noise patterns

Nikolaus Gradwohl2016-04-18T04:49:49+02:00

I used the processing noise function to generate random masks and added them on top of each other using the tint function. This creates some interesting camouflage patterns

click on the image to run them

BookScanner part3 - remote Controll cable

Nikolaus Gradwohl2016-04-07T06:09:01+02:00

In part2 I installed the alternative chdk-firmware on my Canon A-490 cameras, because they allow to trigger the autofocus and the shutter function by using a USB cable. To Trigger these functions you need a cable that connects and disconnects the +5V line of a USB cable. The Data lines of the cable aren't used.

For my bookscanner I need to take a picture of the right and the left page of the book at the same time so I hooked up two usb-micro connectors to an USB-A connector and added a switch on the +5V cable. I connect the USB-A connector to a wall-plug and every time I press the switch the autofocus starts and a picture is taken when I release it again.

Works like charm. Now I need to create a mount for my cameras so they can be positioned correctly below the pages.

Green Desktop Image Generator

Nikolaus Gradwohl2016-03-24T06:58:46+01:00

I wrote a simple processing sketch today that allows me to generate green,noise-based, blocky, desktop-background images. So if you are in urgend need of one of those - like me - copy the code below and run it in processing :-)

example

you can also Download a hires version in case you are to lazy to run the code yourself

void setup() {
  size(1960,1280);
  noLoop();
  noStroke();
  colorMode(HSB, 255,255,255);
}

float s = 50;
void draw() {
  noiseSeed( frameCount );
  int wx = int(width/s);
  int wy = int(width/s);
  for( int x = 0; x<=wx; x++) {
    for( int y =0; y<=wy; y++) {
      fill( 50, 256, noise(x/2.0,y/2.0)*64+128);
      rect(x*s,y*s,s,s);
    }
  }
}

void keyPressed() {
  redraw();
}

keyed particles experiment 2 - time

Nikolaus Gradwohl2016-03-22T05:17:49+01:00

For this animation I used a keyed-particle system and changed the time and the duration values for each stop.

I used a sphere and two cubes as my particle emitters. The first particle system is a particle system on the sphere with no physics to make the particles static.

Then the keyed particles move on to a particle system on a cube where the particles get moved my a forcefield.

Then the keyed particles move to the second cube where the particles again have no physics but are distributed in a grid.

And finally the move back to the sphere where they started.

keyed particle experiment

Nikolaus Gradwohl2016-03-21T06:39:46+01:00

For this animation I used 3 different particle systems and one that uses them as target for a keyed particle system.

The first particle system has no physics at all and sits on a cube. The second particle system uses fluid particles. And the third one uses newton particles on an ico-sphere that get influenced by a forcefield.
