Hi there,

I’ve got code up and working with with the old Kinect V1 camera and I am trying to get it working with KinectV2. I am running into a few problems regarding 3 functions that are being called in my code so far. The specific method that I am running into problems with is the update() method. It calls:

- getDistanceAt(x, y)
- getWorldCoordinateAt(x, y);
- kinect.getColorAt(v.x + 320.0, v.y + 240.0);

that are not transferable from the ‘ofxKinect’ add-on to either the ‘ofxKinectForWindows2’ (@elliotwoods)or the ‘ofxKinect2’ (@sadmb) addon. I am assuming that I need to implement something from the new SDK along with some sort of coordinate mapping but I am having trouble getting past this point. If someone could help me out, or point me in the right direction I would appreciate it.

Below is the method that calls these functions:

```
void ofApp::update(){
// this comment is the old update function that works
//this->kinect.update();
kinect.update();
del.reset();
unsigned char* pix = new unsigned char[640 * 480];
unsigned char* gpix = new unsigned char[640 * 480];
for (int x = 0; x < 640; x += 1) {
for (int y = 0; y < 480; y += 1) {
float distance = kinect.getDistanceAt(x, y);
int pIndex = x + y * 640;
pix[pIndex] = 0;
if (distance > 100 && distance < 1100) {
pix[pIndex] = 255;
}
}
//if you change this, it will break
blob.setFromPixels(pix, 640, 480, OF_IMAGE_GRAYSCALE);
int numPoints = 0;
for (int x = 0; x < 640; x += pointSkip * 5) {
for (int y = 0; y < 480; y += pointSkip * 5) {
int pIndex = x + 640 * y;
if (blob.getPixels()[pIndex] > 0) {
ofVec3f wc = kinect.getWorldCoordinateAt(x, y);
wc.x = x - 320.0;
wc.y = y - 240.0;
if (abs(wc.z) > 100 && abs(wc.z) < 2000) {
wc.z = -wc.z;
wc.x += ofSignedNoise(wc.x, wc.z)*noiseAmount;
wc.y += ofSignedNoise(wc.y, wc.z)*noiseAmount;
wc.x = ofClamp(wc.x, -320, 320);
wc.y = ofClamp(wc.y, -240, 240);
del.addPoint(wc);
}
numPoints++;
}
}
}
if (numPoints > 0)
del.triangulate();
for (int i = 0; i < del.triangleMesh.getNumVertices(); i++) {
del.triangleMesh.addColor(ofColor(255, 255, 255));
}
for (int i = 0; i < del.triangleMesh.getNumIndices() / 3; i += 1) {
ofVec3f v = del.triangleMesh.getVertex(del.triangleMesh.getIndex(i * 3));
v.x = ofClamp(v.x, -319, 319);
v.y = ofClamp(v.y, -239, 239);
ofColor c = kinect.getColorAt(v.x + 320.0, v.y + 240.0);
if (!useRealColors)
c = ofColor(255, 100, 100);
c.a = colorAlpha;
del.triangleMesh.setColor(del.triangleMesh.getIndex(i * 3), c);
del.triangleMesh.setColor(del.triangleMesh.getIndex(i * 3 + 1), c);
del.triangleMesh.setColor(del.triangleMesh.getIndex(i * 3 + 2), c);
}
convertedMesh.clear();
wireframeMesh.clear();
wireframeMesh.setMode(OF_PRIMITIVE_TRIANGLES);
for (int i = 0; i < del.triangleMesh.getNumIndices() / 3; i += 1) {
int indx1 = del.triangleMesh.getIndex(i * 3);
ofVec3f p1 = del.triangleMesh.getVertex(indx1);
int indx2 = del.triangleMesh.getIndex(i * 3 + 1);
ofVec3f p2 = del.triangleMesh.getVertex(indx2);
int indx3 = del.triangleMesh.getIndex(i * 3 + 2);
ofVec3f p3 = del.triangleMesh.getVertex(indx3);
ofVec3f triangleCenter = (p1 + p2 + p3) / 3.0;
triangleCenter.x += 320;
triangleCenter.y += 240;
triangleCenter.x = floor(ofClamp(triangleCenter.x, 0, 640));
triangleCenter.y = floor(ofClamp(triangleCenter.y, 0, 480));
int pixIndex = triangleCenter.x + triangleCenter.y * 640;
if (pix[pixIndex] > 0) {
convertedMesh.addVertex(p1);
convertedMesh.addColor(del.triangleMesh.getColor(indx1));
convertedMesh.addVertex(p2);
convertedMesh.addColor(del.triangleMesh.getColor(indx2));
convertedMesh.addVertex(p3);
convertedMesh.addColor(del.triangleMesh.getColor(indx3));
wireframeMesh.addVertex(p1);
wireframeMesh.addVertex(p2);
wireframeMesh.addVertex(p3);
}
}
delete pix;
delete gpix;
