ProcessingでLifeCamCinemaを使ってみた

最近JavaScript版のProcessing.jsもjsdo.itで夜な夜ないじってますが、
今回はただのProcessingでLifeCam Cinemaを使ったみた。

float rotx = PI/4;
float roty = PI/4;

int sz;

int delay=160;
void setup() 
{
  size(1280, 900, P3D);
   m = new JMyron();//make a new instance of the object
  m.start(320,240);//start a capture at 320x240
  m.findGlobs(0);//disable the intelligence to speed up frame rate
  
  tex = createImage(320,240,RGB);
  tex.loadPixels();
  textureMode(NORMALIZED);
  fill(255);
  stroke(color(44,48,32));
   minim = new Minim(this);
  minim.debugOn();
  
  // get a line in from Minim, default bit depth is 16
  in = minim.getLineIn(Minim.STEREO, 512);
}

  // Given one texture and six faces, we can easily set up the uv coordinates
  // such that four of the faces tile "perfectly" along either u or v, but the other
  // two faces cannot be so aligned.  This code tiles "along" u, "around" the X/Z faces
  // and fudges the Y faces - the Y faces are arbitrarily aligned such that a
  // rotation along the X axis will put the "top" of either texture at the "top"
  // of the screen, but is not otherwised aligned with the X/Z faces. (This
  // just affects what type of symmetry is required if you need seamless
  // tiling all the way around the cube)
