 Orient3D prepares surface models created by [[Other:DSX:Surface3D:Surface3D_Overview|Surface3D]] (or third-party software such as Mimics and ScanIP) for use in kinematic analyses after they have been tracked in [[Other:DSX:X4D:X4D_Overview|X4D]] or [[Other:DSX:Locate3D:Locate3D_Overview|Locate3D]]. With it you can define a [[Other:DSX:DSX_Definitions#Coordinate_Systems|local coordinate system (LCS)]] for each object, landmarks, such as ligament attachment sites, and [[Other:DSX:DSX_Definitions#Region_of_Interest_(ROI)|regions of interest (ROIs)]], which are used in the calculation of distance maps. The local coordinate system of an object is usually, but not necessarily, its “anatomical” reference frame. When a local coordinate system is defined for an object, it is stored in the subject file as a transform from the frame of the object’s segmented image data to the local coordinate system. To analyze tracking results from [[Other:DSX:X4D:X4D_Overview|X4D]] in [[Visual3D:Visual3D_Overview|Visual3D]], the surface model, landmarks, and regions of interest must be saved in the local coordinate system. Even if you are not exporting your data for kinematic analysis in Visual3D, it is still recommended to define the anatomical coordinate system in Orient3D. X4D's tracking results are output using this coordinate system, and it is easier to manipulate the bone in X4D when an anatomical coordinate system is defined.
