The Recalc command is used to update the workspace by re-processing key calculations after any model changes are made. This is often necessary when new segments or landmarks have been added, or when model-based computations may no longer be in sync with the current model structure.

When executed, Recalc performs a comprehensive rebuild of the workspace by:

• Rebuilding all models
• Recomputing model-based landmarks and pose (position and orientation)
• Reassigning force platforms
• Recomputing kinematics and kinetics
• Recomputing center of mass
• Updating report graphs and display windows.

You can actually customize the commands that are executed when the Recalc is run. These are listed under the RECALC Pipeline, whic

The Recalc command is used to rebuild and update all model-based data for every file in the workspace. It performs a wide range of recalculations including models, landmarks, kinematics, kinetics and more.

This command is especially important after making changes to:

• A model definition
• A pipeline command affecting landmarks and forces
• Any updates that alter segment pose, orientation, or relationships.

The command also executes the user-defined Recalc pipeline, which can include any custom commands (e.g. additional calculations or filtering) that the user wants to run automatically during recalculation.

When the command is executed (or the button is clicked), Visual3D performs the following in order:

1. Reprocess Force Platforms: If the setting for “Use Processed Analog” is enabled, force plate data is recomputed.

2. Rebuild All Models: All models in the workspace are regenerated.

3. Compute Landmarks and Pose: All landmarks and segment positions/orientations are recalculated.

4. Assign Force Platforms: Forces are re-mapped to the correct foot segment based on location/contact.

5. Compute Assigned Forces: Net force and moment vectors are recalculated at the assigned foot.

6. Compute Kinematics and Kinetics: Joint angles, moments and forces are recalculated.

7. Compute Center of Mass: Whole-body center of mass is updated.

8. Execute Recalc Pipeline: Any user-added commands in the Realc pipeline list box are executed (e.g., filters, custom metrics)

9. Update UI and Report Graphs: Any new data is shown in the UI, and graphs are refreshed.

The command below is as seen on the Visual3D application, it has many parameters as there are many options to manipulate this command.

Recalc

;

This command does not have any parameters. It will always execute the default and user-defined Recalc processes on all files in the workspace.

There is no dialog box for this command due to it being a stand-alone function. The application interface alternative option is the recalc button on the toolbar:

The following examples will go through the use of the Recalc command in the Visual3D application.

Recalculates the Workspace.

Recalc
;

Rebuilds any model(s) and any landmarks dependent on the model(s). The Recalc command also executes the RECALC Pipeline. In addition if any changes have been made to the Events then Recalc will update any Report Graphs dependent on these events. As a general rule, anytime a change has been made to the EVENT LABELS or to PROCESSED signals that may effect the results in the report, it is always safest to RECALCULATE the workspace before printing the report or saving the CMO file.
