Full socket.io client and server example

To see a full explanation, read my answer on SO here: https://stackoverflow.com/a/24232050/778272.

How to use

Create a folder, run npm init -f on it and paste both server.js and client.js there (see files below). Needless to say, you must have Node.js installed on your system.

Install the required libraries:

void getQuaternion(Mat R, double Q[])
{
    double trace = R.at<double>(0,0) + R.at<double>(1,1) + R.at<double>(2,2);
 
    if (trace > 0.0) 
    {
        double s = sqrt(trace + 1.0);
        Q[3] = (s * 0.5);
        s = 0.5 / s;
        Q[0] = ((R.at<double>(2,1) - R.at<double>(1,2)) * s);
