Webcam with stable framerate (>=25fps) on high resolution.

Although advertised differently even the best HD webcams like the Logitech Quickcam Vision (for Mac) don't let me capture on 25 or 30fps on HD resolution (Logitech has a lot of "HD" sizes).

I've used it in this installation: http://vimeo.com/70725478

However the framerate changes (probably depending the light situation) between 25fps and 15fps (when in 25fps mode).

I've read the same about the Microsoft LifeCam:

Does anyone have some other recommendations (that you've tested), preferably UVC compatible?

I have also a Sony PS Eye camera lying around, both that doesn't serve for higher resolutions either (and is more difficult regarding drivers).

In Processing 1.5.1 I see all my cameras, but in Processing 2.08b I only see my build in webcam.

I know the video implementation was changed in Processing 2.0. I would like to be able to use my PS3 Eye camera with Processing 2.0

Platform: OSX 10.7.5.

I've used the standard Capture list sketch: http://processing.org/reference/libraries/video/Capture_list_.html

ControlP5 annotations

Great to see that adding controllers by annotations is now supported by ControlP5 natively. I've found out the possibility by the CP5magic announcement of Toxi but I could get it to work. Luckily I've found out that its now implemented in ControlP5 itself.

However I only have this example:

http://www.sojamo.de/libraries/controlP5/examples/use/ControlP5annotation/ControlP5annotation.pde

And I would like to know how I can make a list with some values with an annotation.

This would by the interface I would like to make. Toggle and slider don't seem a problem.

I couldn't find something in the documentation.

GLGraphics alpha masks support?

Hi,

I'm trying to mask a texture (webcam image) with a drawn mask. I'd like to get the same effect as the processing mask function.

However working with a grayscale image doesn't seem to work. I now draw the mask with a cutout (breakshape) to make my mask working, however I cannot soften the edges.

See code below:
2. // Generate maskTexture
3. maskTex = new GLTexture(parent, imageSize, imageSize);
5. // Generate maskedTexture
6. maskedTex = new GLTexture(parent, imageSize, imageSize);
8. // Generate mask and store it in maskTex
9. pg = createGraphics(imageSize, imageSize, JAVA2D);
11. pg.beginDraw();
12. //background(gray, alpha);
13. //pg.background(255,255); //white
14. pg.background(0, 0); // black
15. pg.smooth();
17. //fill(gray, alpha)
18. //pg.fill(255, 255, 0); // yellow
19. pg.fill(0, 255);
20. pg.noStroke();
22. pg.beginShape();
24. pg.vertex(0, 0);
25. pg.vertex(imageSize, 0);
26. pg.vertex(imageSize, imageSize);
27. pg.vertex(0, imageSize);
29. pg.breakShape();
31. // order is important
32. pg.vertex(int(x2+translateX), int(y2+translateY));
33. pg.vertex(int(x1+translateX), int(y1+translateY));
34. pg.vertex(int(x3+translateX), int(y3+translateY));
36. pg.endShape(CLOSE);
37. pg.endDraw();
39. //pg.filter(BLUR, 12);
41. maskTex.putImage(pg);
43. maskFilter.apply(new GLTexture[] {eyeTex, maskTex}, maskedTex);
With the mask method in Processing I just drew a triangle and blurred it and it work fine. Below the drawing code. I'd like to be able to use this as a mask in GLgraphics (softened edges).
2. // Generate mask
3. pg = createGraphics(imageSize,imageSize,JAVA2D);
5. pg.beginDraw();
6. pg.background(0); // black
7. pg.smooth();
8. pg.noStroke();
9. pg.fill(255);
11. pg.pushMatrix();
12. pg.translate(translateX, translateY);
13. pg.triangle(x1, y1, x2, y2, x3, y3);
14. pg.popMatrix();
15. pg.endDraw();
17. pg.filter(BLUR, 4);
Can I use alpha masks with GLGraphics ? And if yes how?

And if not why I still see a stroke of 1 pixel when masking?

I'd like to keep using GLGraphics because its way faster.

The code I currently use (uses GSVideo and GLgraphics):

oscP5 oscEvent get port data

I'm building an OSC monitor/patcher that has to be able to listen to mulitple ports.

As far as I found out that will be only possible by making multiple OscP5 objects that each listens to their own port. I've tested this with 2 ports and that works perfect.

However all objects call the oscEvent function. Is there a way to see which OscP5 object triggered the oscEvent function? Or to get more details from the OscMessage?

I've looked into the documentation the only thing I've found that came close was the OscMessage print() method.

This is what I its prints for a message send to port 8000:

-OscMessage----------
received from    /192.168.0.101:63405
addrpattern    /1/fader1
typetag    f
[0] 0.30240548

And this for a message to port 3333:

-OscMessage----------
received from    /192.168.0.104:50643
addrpattern    /tuio/2Dcur
typetag    si
[0] fseq
[1] 1330

The port is not similar it seems? The ip-adres is correct.

Questions:
1. Can I get the port and/or the ip-adress from the message with a certain method?
2. Is it smart to listen to multiple ports by making multiple OscP5 objects? Is there a certain limit of objects that can be run or is this just trial and error?
3. I've understood that its is easy to send messages to different ports by using the Flush() method. Is that right? Or would using multiple netAdress objects be a better idea as stated in this example on the Processing forum.

oscP5 string problem with OscMessage

Hi,

I try to make a Scratch <> OSC bridge.

However have some problem to convert incoming string to a custom OSCMessage. It seems that OscMessage doesn't recognize the incoming part of the String.

String received from Scratch: sensor-update "position" -87.0

Could it be an encoding problem? Since Scratch encodes strings as UTF-8.
Or is it related to the library?
1. String receivedString = scratchClient.readString();
2. println("incoming string: "+receivedString);
4. String[] tokens = splitTokens(receivedString);
6. String scratchMessageType = tokens[0];
7. println("incoming scratch message type: "+scratchMessageType);
9. // send OSC message
10. //String sendOscString = "/scratch/"+scratchMessageType+"/"; // doesn't work
11. String sendOscString = new String("/scratch/"+scratchMessageType+"/"); // doesn't work
12. //String sendOscString = "/scratch/"; // works
14. OscMessage myMessage = new OscMessage(sendOscString);
15. myMessage.add(123);
16. oscP5.send(myMessage, myRemoteLocation);
My Processing code including a Scratch example in a zip-file

If you try it with Scratch don't forget to enable the remote connections. See this post.
