Hello Doug ,
I am currently working on a project and have used tracker to do the 2D video analysis.
My next step in the project is to develop or start working on ideas to make 2D analysis  into a 3D video analysis.I have multiple cameras and the resources.U hope to use tracker for the same.I am fine with the learning curve being steep and long.I just need some ideas and advice on the same.
Thank you,
Vijay Padmanabhan
