How to interact with the information moddel get?

[tphlru]

I have installed mmtrack and want to use it to count people crossing a virtual line (entering a building, for example). However, when I read all the documentation, I could not find any method that is able to interact with specific object coardinates, which is required to count line crossings. Then I could hardly find any way to interact with the information I get, now it seems to me that your library is just a way to show how models work. But it's not, is it? Can you tell me more about it, maybe you can give me some more code examples?
