When running a simple sketch with a sphere in a browser the web console kicks out this message:
"[17:06:39.457] Error: WebGL: Drawing without vertex attrib 0 array enabled forces the browser to do expensive emulation work when running on desktop OpenGL platforms, for example on Mac. It is preferable to always draw with vertex attrib 0 array enabled, by using bindAttribLocation to bind some always-used attribute to location 0. @ http://127.0.0.1:61971/processing.js:5274"

It renders fine, but is there something I should be setting that I'm not?

I'm building a project in Processing 2.09b, and it exports fine, however, people multiple with Mountain Lion cannot open the application file. I made a "hello world" sketch and had the same problem. Is there an easy workaround?

Thanks in advance

I am running this code on the Galaxy Tab 2. It shows an image, but I would like a live video and the image stops updating after a second. If anyone can see something obvious that I'm missing I'd be much obliged.

1. import ketai.camera.*;
   KetaiCamera cam;
   
   void setup() {
     orientation(LANDSCAPE);
     cam = new KetaiCamera(this, 320, 240, 24);
    // int camnum = cam.getNumberOfCameras();
     cam.setCameraID(1);// changes the camera to the front.
     cam.start();
   }
   
   void draw() {
   }
   
   void onCameraPreviewEvent()
   {
     cam.read();
     cam.loadPixels();
     image(cam, 0, 0, 320, 240); // Draw the webcam video onto the screen
     println("previewing");
   }
   
   void exit() {
     cam.stop();
   }
   

The apWidget video example is not working with android 4.0 on my galaxy 2 tablet. The file's audio plays but there is no video. Anyone have a work around, or another method for showing video?

I'm having a dickens of a time getting a spotlight to orient the same direction as the camera. I'm using the OCD library and want the spotlight to act as a headlight as we move and turn through the space. Any help at this point would be greatly appreciated. I've included some rough code below.

w- forward
s - back
a - slide right
d - slide left
j - turn left
k - turn right
