[IGSTK-Users] Single marker tracking

[Patrick Cheng]

Hi Eric,

When you refer to "single marker", do you mean a single reflective ball?

Polaris tracker can not track a single marker(it can not distinguish one 
from another, not calculate the coordinate and pose information)

There are applications, especially in augmented reality, in which you 
can tracker a cluster of markers.

Some of the trackers supported by IGSTK might be able to do that, but 
the current API does not support single marker tracking.
