openGL Already called beginDraw() error on Processing 2.0 b3

Hi guys,

I'm trying to run a few sketchs in P3D (openGL) mode and I'm getting this "Already called beginDraw()" error that halts the program.

It happens with the controlP5 2.0.1 "controlFrame" example below (running on Processing 2.0 b3).

I put this thread on the Core Library section because I think it's openGL related. The controlP5 is just an example.
2. /**
3. * ControlP5 Controlframe
4. * with controlP5 2.0 all java.awt dependencies have been removed
5. * as a consequence the option to display controllers in a separate
6. * window had to be removed as well.
7. * this example shows you how to create a java.awt.frame and use controlP5

24. cp5 = new ControlP5(this);

27. // by calling function addControlFrame() a new frame is created and an instance of class ControlFrame is instanziated.

31. // and proceed to create new controllers as usual.

Kinect SimpleOpenNI average point tracking

Hi guys,

Can I use an average point tracking function like in Shiffman's OpenKinect but using the SimpleOpenNI library?
I see something similar on the 2D slider example, but it's based on relative hand position, not absolute.

I'd also like to be able to set a Z threshold for the tracking.

Dear friends, how can I upload an image using the twitter4j library?

I already have this code running ok for posting text, using twitter4j 2.1.4 and Processing 2.0 alpha 8.
2. import twitter4j.conf.*;
3. import twitter4j.internal.async.*;
4. import twitter4j.internal.org.json.*;
5. import twitter4j.internal.logging.*;
6. import twitter4j.http.*;
7. import twitter4j.api.*;
8. import twitter4j.util.*;
9. import twitter4j.internal.http.*;
10. import twitter4j.*;
11. String msg = "Automatically posted from Processing";
13. String consumer_key = "my key";
14. String consumer_secret = "my secret";
15. String oauth_token = "my token";
16. String oauth_token_secret = "my token secret";
17. color bgcolor = color(255);
18. long timer;
20. void setup() {
21. size(640,480);
22. }
24. void draw() {
25. background(bgcolor);
26. if (millis()-timer > 2000) bgcolor = color(255);
27. }
29. void mousePressed() {
30. Twitter twitter = new TwitterFactory().getOAuthAuthorizedInstance (
31. consumer_key, consumer_secret,
32. new AccessToken( oauth_token, oauth_token_secret) );
34. try {
35. Status st = twitter.updateStatus(msg + " " + second());
36. println("Successfully updated the status to [" + st.getText() + "].");
37. bgcolor = color(0,0,255);
38. timer = millis();
39. }
40. catch (TwitterException e) {
41. println(e.getStatusCode());
42. }

Checking clicked word

Hi guys,

I'm making a dictionary like applet for ancient greek poetry.
I need to check what word the user clicked (or is mousing over) per line. Each line has aorund five words, with a font that is not monospaced.
I'm thinking about a solution that has the pixel size and position of each word hard coded. Any better ideas?

Here's how I'm displaying the text:
1. PFont fontGreek;
3. void setup() {
4. size(800,600);
5. fontGreek = createFont("Athens", 16, true);
6. } // end setup
8. void draw() {
9. background (255);
10. textFont(fontGreek); fill(0);
11. text("Ζεὺς μὲν ἀφίκτωρ ἐπίδοι προφρόνως\n"+
12. "στόλον ἡμέτερον νάιον ἀρθέντ᾽\n" ,20, 60);
13. } // end draw
Thanks.

Quase-Cinema Feijoada Remix (VJ app)

Hi guys,

I've released the code for my new live video performance application "Quase-Cinema Feijoada Remix".
The project is on it's very beginning, but the source is open and it's already running ok. The software is supposed to replace my previous performance app, made in openFrameworks, Quase-Cinema 2 (also open source).
It allow the mixing of 4 video layers, pixel effects, video mapping (quads and berzier), BPM rythm creation and Midi control.
It's built on Processing 2.0 (alpha 4), and the performance is smoking - thanks to the new 2.0 architecture, GSvideo and openGL. I'm realy enjoying to be making this in Processing, as the whole environment and community and very mature.

Great thanks to all the people that have made this possible:
- Ben Fry, Casey Reas and the Processing development team
- Andreas Schlegel (controlP5 and sDrop)
- Andres Colubri (GSvideo)
- Damien Di Fede (Minim)
- Marcin Ignac (Projected Quads)
- Patrick Saint-Denis (mappingtools)
- Severin Smith (the MidiBus)

A short talk about the release (with English subtitles): http://www.youtube.com/watch?v=xyWRigLv67U
