Hi there. I need figure out something guys. I find out Positions but can't figure out Rotation. There are values but they don't make any sense. I tried multiple them by 360.0 with not good results.
On the image i manually set the most correct object rotation but can't find these values. Are they converted somehow? I serached for floats, doubles and nothing. It's possible that rotation are writen in integrers/shorts and converted with float modifier?

Another example... As you can see object without any rotation has whole number.

Found something... Maybe it is that case. But can't figure out how to convert it as Template for 010 HEX Editor. I think the order is x,y,z and it has something with "Tait-Bryan angles". All what i need is convert these values to degrees. If someone has an idea please help. Thanks in advance!

Code:

// Checks if a matrix is a valid rotation matrix.
bool isRotationMatrix(Mat &R)
{
    Mat Rt;
    transpose(R, Rt);
    Mat shouldBeIdentity = Rt * R;
    Mat I = Mat::eye(3,3, shouldBeIdentity.type());

    return  norm(I, shouldBeIdentity) 
}

// Calculates rotation matrix to euler angles
// The result is the same as MATLAB except the order
// of the euler angles ( x and z are swapped ).
Vec3f rotationMatrixToEulerAngles(Mat &R)
{

    assert(isRotationMatrix(R));

    float sy = sqrt(R.at(0,0) * R.at(0,0)    R.at(1,0) * R.at(1,0) );

    bool singular = sy 
    float x, y, z;
    if (!singular)
    {
        x = atan2(R.at(2,1) , R.at(2,2));
        y = atan2(-R.at(2,0), sy);
        z = atan2(R.at(1,0), R.at(0,0));
    }
    else
    {
        x = atan2(-R.at(1,2), R.at(1,1));
        y = atan2(-R.at(2,0), sy);
        z = 0;
    }
    return Vec3f(x, y, z);

}

Structure of file is like:

Got it. Order is Z,Y,X

Now how to write code for 010 template to parse and output results???
