Vicon ProCalc Theia Tutorial
Vicon Nexus 2.12 and later, together with ProCalc 1.5 and later, adds full support for kinematic calculations based on Theia Markerless software (Theia3D). This tutorial explains how to create your own kinematic calculations in ProCalc, based on a C3D file containing the outputs from Theia3D.
Note
To enable you to calculate joint kinematics without having to create your own schemes, the read-only scheme CalculateKinematicsFromTheia is also provided.
About the data for this tutorial
To follow this tutorial, navigate to C:\Program Files\Vicon\ProCalc\Help and unzip the ProCalc Tutorials Data file. Choose a path or directory that has sufficient read/write permissions and that you can remember and access easily (eg,C:\Users\Public\Documents\Vicon). If you have completed a ProCalc tutorial in the past, you may have already completed this step.
For this tutorial, we will use the Theia Tutorial session. Within this folder, there is one trial (Walk01.c3d).
To access the trials in ProCalc, ensure you have a hierarchy that looks like the example below, though the specific path will depend on the location of your extracted data.
These are the steps for creating your own kinematic calculations:
