====== IOR Gait Full Body Model ======
This tutorial explains how to implement the IOR Full Body Model in Visual3D. \\
The IOR Full Body Model is a combination of the IOR Multi-Segment Trunk, and the IOR Lower Extremity Model.
The naming convention in this tutorial follows Serge Van Sint Jan's convention.

==== Planar Angles ====
To calculate the orientation of the trunk segments, planar angles are calculated to determine the orientation
of the various segments relative to one another. To calculate a planar angle, you need to either reference the 
ORIGINAL or PROCESSED folder when defining a target. If your targets have not been filtered or interpolated,
you will not have a processed folder and will need to use the ORIGINAL. However, if you plan to process your target
data in any way, you should do this now, prior to creating you planar angles. \\
{{:iorfb_trunksegments.png?500|This image was taken from the Multi-Segment trunk paper}} \\
The following abbreviations are used in naming the planar angles
  * **FE** Flexion/Extension
  * **LB** Lateral Bending
  * **AR** Axial Rotation

    * **X:** 0.0 **Y:** 0.0 **Z:** -0.05
  - **Do NOT Check:** Offset by Percent (1.0 = 100%) (Meters when not checked)
  - **Do NOT Check:** Calibration Only Landmark (Not generated for assigned motion file(s))
=== FE Planar Angles ===
Below defines the orientation (flexion/extension) of the adjoining spine segments resolved in the pelvis coordinate system \\
**NOTE:** For the FE Planar Angles, the same definitions for the angles are used for both the left & right side. This
means the different sets of signals do not need to be created for the left and right sides (as with the LB and AR planar angles). \\
**NOTE-2:** To access these dialogs, you need to edit a command pipeline, the [[visual3d:documentation:pipeline:signal_commands:compute_planar_angle|"Compute_Planar_Angle" pipeline command]].
