Tango pose data is calculated as a transformation between two frames of reference (so, for example, you can be asking for the pose of the device within a learned area).
This struct is used to specify the desired base and target frames of reference when requesting pose data. You can also use it when you have a TangoPoseData structure returned from the API and want to examine which frames of reference were used to get that pose.
For more information, including which coordinate frame pairs are valid, read here.
- Base Frame [ETango Coordinate Frame Type Enum]: The co-ordinate from which to obtain the 'starting position' of a given pose, e.g. the point in space where the tango was present when the service started up.
- Target Frame [ETango Coordinate Frame Type Enum]: The co-ordinate from which to obtain the 'current position' of a given pose, e.g. the current position of the Device.
