Add own points to calculation

[markxma1]

hi, is there some way to add own points (got from Marker) to calculate (and keep the ID of each point.)?
I need to find some regions in 3D.

I hava added points as SHIFT format (created for each image ViewID.shift.feat/desc file and one 0.matches.txt file where are point matches stored.).

feat file:
x y 0 10 (Line id is the point id, last one is size. I have set all point to 10.)

desc file:

void saveDescsToBinFile(const std::string &sfileNameDescs, size_t nbFeats)
{
	std::ofstream file(sfileNameDescs.c_str(), std::ios::out | std::ios::binary);
	if (!file.is_open())
	{
		throw std::runtime_error("could not open file " + sfileNameDescs);
	}
	//Write the number of descriptor
	const std::size_t cardDesc = nbFeats;
	file.write((const char *)&cardDesc, sizeof(std::size_t));
	for (int j = 0; j < nbFeats; ++j)
	{
		for (int i = 0; i < 128; ++i)
		{
			unsigned char x = 0;
			file.write((const char *)&x,
					   sizeof(unsigned char));
		}
	}
	const bool bOk = file.good();
	file.close();
}

and matches file:

img1ID img2ID
1
sift points count (length of array with matches pairs <points from img1, points from img2>)
Point1IdIMG1 Point1IdIMG2
Point2IdIMG1 Point2IdIMG2
Point3IdIMG1 Point3IdIMG2
....
img1ID img2ID
1
sift points count
Point1IdIMG1 Point1IdIMG2
Point2IdIMG1 Point2IdIMG2
Point3IdIMG1 Point3IdIMG2
.....
