Leap - Javascript ?

Hey guys,

Is there a possibility to export my leap featuring Processing sketches to get them running in the web ?

According to the developer (and probably some more of you guys) the problem is the usage of libraries when exporting to a javascript.

Has anyone a solution ? Hint ? Anything ?

Thanks,

Leap Motion - Tracking both hands ?

Hey guys,
Anyone tried the LEAP Motion + Processing ?

I stuck at the point where I can track both hands… at the moment the code looks like this:
2. for (Hand hand : leap.getHandList()) {
4. PVector handPos = leap.getPosition(hand);
5. playerpos = handPos.y;
6. }
I just need the y axis but how do I transform the "hand" command to the second hand ? I use the LeapMotionP5 Library and somewhere I read that the first recognized hand is hand 0, the second one hand 1 … Would be great if anyone can tell me how to separately use them.

The gesture recognition example can handle two hands separately but has also this code:
2. for (Hand hand : leap.getHandList()) {
3. PVector handPos = leap.getPosition(hand);
4. ellipse(handPos.x, handPos.y, 20, 20);
5. }
Thanks,

Transparent Canvas in Processing Jar ?

Hey,

I try to export a Processing Jar document with a transparent canvas.

I tried:

/* @pjs transparent=true; */

first but this didn't work,

then I found a sketch:

http://www.openprocessing.org/sketch/74380

and tried the first line, too.

                   
                      parent.document.getElementById("appletAjaxContainer").setAttribute("style", "background-color:transparent; border:0px;");

but this didn't work, too.

Has anyone an idea how to do that ?

Hey,

Can anyone explain to me how to recreate a Image Url ?

I want the programm to give me the latest Picture posted on a website. I thought about something like

loadImage = ("http://fixedurl.com/" +"X" + ".jpg");

is there a way to let processing figure out what X is ?

thanks a lot,

Record sound and convert to ?String?

Hey guys,

I would like to let processing record a sound (microphone) and let it save this as a Boolean Array (?)

In the end it should be something like a morse code (yes /no ) to let the program in the following give me the opportunity of a comparison between the recorded sound and the current microphone input.

Hope you get the basic idea behind it ?!

So my question would be what's the easiest way to record and save a sound in Array?

thanks a lot

RFID read & write via processing?

hey there,
I just came up with the idea to try some kind of RFID reading with processing.

The software you get with a Ehouyan RFID read/writer is - expecially for macs - still in its infancy…

I found some libraries and code examples from guys trying this before. But it seems like none of them are working with this reader ?

Can perhaps anyone here help me out who has some kind of script making reading (or writing) of rfid cars possible ?

I would also appreciate some tips & tricks :)

Would be greate :)

How to fill a vertex with hash lines ?

Hey guys,
I just wrote a script with some statistics in it and I don't like what it looks like when I just get this flat look a vertex normaly has…

I found a link to a "how to fill a ellipse with hashlines"
1. float startAngle;
  float density;
  float radius;
  void setup() {
  size(800,800);
  smooth();
  stroke(0);
  noFill();
  startAngle = PI/3;
  radius = 380;
  density = 0.01;
  }
  void draw() {
  background(255);
  startAngle = atan2(height/2-mouseY,width/2-mouseX);
  translate(width/2,height/2);
  noFill();
  stroke(0);
  strokeWeight(0.5);
  for(float i = -1; i <1;i+=density) {
      float angle = acos(i);
      line(cos(startAngle+angle)*radius,sin(startAngle+angle)*radius,cos(startAngle-angle)*radius,sin(startAngle-angle)*radius);
  }
  strokeWeight(1.5);
  ellipse(0,0,radius*2,radius*2);
  fill(220,220,0);
  stroke(255);
  for(float i = radius-10; i>0;i-= 15) {
      ellipse(0,0,i*2,i*2);
  }
  }
The filling of the outer ring is pretty much what I want the vertex to look like.

Is there anyone out there who perhaps already did this and can help me out ?

Best regards & thanks for your help…

Multiple String loading

hey. I guess this is pretty simple but I don't get it anway :( Hopefully anyone can help me out with this:

When I want to load a textfile i have to add the breaks ( \n) happening here
2. for (int i=0; i < news.length; i++)
3. {
4. s += news[i] + "\n";
5. println (s);
6. }
Well this works perfectly as long as I got only one textfile. My problem is that I now have about 15 files and I don't want to start my script with 15 times for…

Is there a way I can compress it in 2 for loops, my idea was:
3. for ( int j=0;j < 15; j++)
4. {
5. for (int i=0; i < news[j].length; i++)
6. {
7. s[j] += news[j][i] + "\n";
8. println (s[j]);
9. }
But this couldn't work because "s" isn't an array…

is there something I can do to get this to work?

best regards

Custom Cursor in 3D ?

Hey,
sorry for posting all this (silly?!) questions but I can't even find an answer via google (just for processing alpha and this doesn't seem to work…)

I want a custom cursor in a 3D processing script, in 2D everything went well, code:
2. void setup () {
5. size(300, 300);
6. }
9. void draw () {
10. noCursor();
11. background (255);
12. KREUZ(mouseX, mouseY);
13. }
17. void KREUZ (int x, int y)
18. {
19. line (x-(width+x), y, x+(width-x), y); //KREUZ X achse
20. line (x, y-(height+y), x, y+(height-y)); //KREUZ y achse
21. }
I also tried to generate the cross in a .svg and load it as cursor(cross.svg)

in both variations I have the same problem:

as soon as i put it outside of the push popMatrix() which sets up my object it lies BEHIND it … not in front …

sounds like a simple problem but I don't get it neither…

thanks a lot for your help again…

Connecting zoom and object size ?

Hey,
I got another question relating to the script I posted yesterday:

I have a map and I'm able to zoom in + out.

Now I have some popups you can push up when you click on diffrent places in the card.

The Problem:

When I'm zoomed in you can't see the popups anymore because they have a fixed size. Is there anyway I can scale it down/up when I'm zoomed ?

the zoom is generated here:
2. void mouseWheel(int delta) {
3. zoom = zoom+=delta;
the map is translated by:
1. translate(0, 0, zoom);
zoom is 400 when you start the programm.

I think the problem is that the popup is a class… That's why the translate doesn't affect the popup ( the popup.generate code is mentioned in another class!)

perhaps anyone can help me out with that :) Would be pretty great :)

Thanks a lot

cheers
