hi,
i found this set of code from http://andybest.net/2008/11/3d-webcam-lines-additive-blending/ but I tried the fix and still have some error :quicktime.QTSession.InitializeQTML(I)S

im using processing 1.5.1

quicktime 7

the code as below :

void setup() {

try {

quicktime.QTSession.open();

} catch (quicktime.QTException qte) {

qte.printStackTrace();

}

size(1024, 768, OPENGL);

pgl = (PGraphicsOpenGL) g;

gl = pgl.gl;

frameRate(30);

video = new Capture(this, width, height, 30);

}

void draw() {

noFill();

lights();

strokeWeight(4);

background(0);

if (video.available()) {

video.read();

video.loadPixels();

background(0);

pgl.beginGL();

gl.glDisable(GL.GL_DEPTH_TEST);

gl.glEnable(GL.GL_BLEND);

gl.glBlendFunc(GL.GL_SRC_ALPHA, GL.GL_ONE);

pushMatrix();

translate(width, height, 0);

rotateY(radians(mouseX-(width)));

rotateX(radians(-(mouseY-(height))));

translate(-width, -height, 0);

int index = 0;

for (int y = 0; y < video.height; y+=5) {

beginShape();

for (int x = 0; x < video.width; x++) {

int pixelValue = video.pixels[x+(y*video.width)];

stroke(red(pixelValue), green(pixelValue), blue(pixelValue), 255);

vertex (x*2, y*2, (brightness(pixelValue)*2)-100);

index++;

}

endShape();

}

pgl.endGL();

popMatrix();

}

}

p/s: thank you for helping me out
