how to read triangle indices from imported model

May 20, 2014 at 1:34 PM
I imported 3d model with helix toolkid. The model is from kinect sensor. The 3d model have parts that are not connected . The object that I scan with the sensor and parts of other objects and the background. How can I read the points and the triangle indices so I can check if they are connected to each other and then create new model just for the object I like.

Any ideas and suggestions?
