What's the proper way to use createImage() dynamically ??

Hi Forum,
Related to my last
post, I'm attempting to create a PImage on the fly from some detected Kinect information in order to pass the image off to a blob detection routine, but I'm not sure exactly how to do that properly...
I am pulling the depthImage from the Kinect, and asking for the xyz points of a Vector if the z point is between two thresholds...
I can draw the vector fine, and even average the points, however imperfectly (which makes me wonder why I'm trying to pass this to a blobDetection routine
), but how would I pass those into a pixel array?
I kind of have it working, but it's just drawing all the pixels at 0,0 (I think)... so I guess I need to know how to assign the x and y positions ??
What I've attempted so far starts on Line 17...
- if(realWorldPoint.z < table && realWorldPoint.z > hover ) {
- // Average XYZ
- sumX += x;
- sumY += y;
- count++;
- if(count != 0 ) {
- handX = sumX / count;
- handY = sumY / count;
- }
- else {
- handX = 0;
- handY = 0;
- }
- stroke(255, 0, 0);
- point(realWorldPoint.x,realWorldPoint.y,realWorldPoint.z);
- // Create PImage To Pass To Blob Detection
- kImg = createImage(width/2, height/2, RGB);
- kImg.loadPixels();
- for(int i = 0; i < count; i++) {
- kImg.pixels[i] = color(0, 255, 255);
- }
- kImg.updatePixels();
- }
Thanks for any feedback / advice.
