Lightweaver-Projection

Searching and thinking about a material, which I can use for a curvey back-projection. It has to be flexible like plastic, half-transparent and white colored. But it has to be a big surface also, like 5 x 3 meter.  I researched on the internet and found some possibilities:

Use a thick plastic foil with half-transparent-paper. Use a “Glas-Decor”-Foil (thick plastic-foil with rough surface *expensive*) Use big thin Paper (120g - 180g)

Code update for Motion Sensor Face Warp Project

After a few test i have seen that the Serial Monitor of the Arduino was sometime wrong and just had wrong data.

Like you can see here:

To kill that for a fluetly installation, i updated the code and inserted a filter. Here is the updated code for the Arduino with comments:

#define trigPin 12 #define echoPin 13

float looper,zwischenspeicher; //global cache & Looper (for init the programm with zero at startup)

void setup() {  Serial.begin (115200 );  pinMode(trigPin, OUTPUT);  pinMode(echoPin, INPUT);  looper=0; //Init with zero  zwischenspeicher=0; //Init cache with zero }

void loop() {  float duration, distance;

 digitalWrite(trigPin, LOW);  delayMicroseconds(2);

 digitalWrite(trigPin, HIGH);  delayMicroseconds(10);  digitalWrite(trigPin, LOW);

 duration = pulseIn(echoPin, HIGH);

 if (looper == 0){  zwischenspeicher = (duration / 2) * 0.0344;  }// save first messure into the cahe

 else {    zwischenspeicher = (zwischenspeicher +( (duration / 2) * 0.0344))/2;  } // addition of the actuall messuringpoint to the chache and divide by two

 looper++; // Looper is going up 1 step

 if (looper >= 100){ //if 100 times messured    distance = zwischenspeicher; //cache is distance  looper=0; // reset looper  zwischenspeicher=0; // reset cache  Serial.println(distance); // output  }

 delay(5); // delay shorter for for output }

Now it looks more like this:

Thinking about Lightweaver

The question was ... how I can get the recipient more into the visual installation, so that someone is thinking he’s really in a another world. So the idea is to give the projection a curvey look. Something like a 180° Projection-Wall. The result should be a effect of immersing into that installation. 

I tried out the curvey projection on a A4-Paper with a little Beamer and two holding boxes. The backprojection is working well and I can imagine, that this setup will immerse the recipient more into the lightweaver.

The next step will be, to produce more visuals which have more thickness at their edges (in the particle system).
