File Commands

File Open/Import

File Commands are separated into three categories:
1) File_Management
2) File_Open/Import
3) File_Save/Export

For more pipeline commands, please see the Pipeline Commands Reference page.

File_Management

Exit_Workspace

Exits Visual3D. This is useful when an external program launches Visual3D with a pipeline. When the pipeline is finished executing, Visual3D is closed.

Recalc

Recalculate the link model, event dependencies, and execute the RECALC Pipeline.

Select_Active_File

Many of the pipeline commands in Visual3D act on the active files only, and only active file is animated in the 3D viewer.

File_New

Clears the Workspace. Removes all models, motion trials, and the Global Workspace.

Assign_Tags_To_File

Files can be associated with other files opened in the Visual3D workspace by assigning a TAG to the file.

Combine_Tags

Use boolean logic to combine TAGS into a new TAG.

Remove_Tags

Removes the specified files from the TAG. Select ALL_FILES, a TAG, or a movement trial.

Copy_Point_Descriptions_To_Point_Labels

Motion Analysis Corporation exports C3D files that are consistent with an early version of the C3D file format. One of the restrictions in the early format was that POINT LABELS (e.g. names of the markers) were allowed to have only 4 characters. This command will cause Visual3D to copy the marker DESCRIPTION PARAMETER into the marker LABEL PARAMETER thus giving markers their long names.

Fix_MAC_Eva7_C3DFile

Visual3D does not act as a general C3D editor. Several commands, however, exist to edit specific parameters in the C3D file:

Modify_Analog_Parameters

This command can be used to change a selection of the ANALOG parameters in a C3D file. There must be the same number of values in the LABELS, SCALE, and OFFSET entries. The command will modify the parameters in order.

Modify_Point_Parameters

The command Modify_Point_Parameters will modify the POINT LABELS (e.g. Marker Names) in the C3D file. The LABELS listed will be applied to the POINT parameters in the order listed in the C3D file. If fewer LABELS are specified in the command than exist in the C3D file, then only the number of LABELS specified will be modified.

Modify_C3D_Subjects_Parameters

Modify the SUBJECT parameter group

Modify_Point_Rate

Modify the point and/or analog rate in the c3d file

Remove_Prefix_From_Point_Labels

Vicon Corporation's Workstation software provides an option to add a prefix to all of the marker labels. This causes Visual3D a big problem because Visual3D assumes that markers are named consistently between files, especially between the standing trial and the movement trials.

Downsample_Data

Not Available In Visual3Dv5:

Modify_C3D_Trial_Parameters

Modify the TRAIL parameter group

File_Open/Import

File_Open

Adds a file to the Visual3D Workspace.

File_Close

Closes the specified File(s).

Import_Data_From_ASCII_File

Imports signals from an ascii file formatted using the Visual3D_ASCII_Format.

Import_Analog_NDI_Signals

Imports Analog signals from NDI Toolbench into a C3D file.

Import_Analog_Signals_From_AMTI_Ascii_File

The ASCII file exported by AMTI is a very simple file with no header, and the data stored in columns.

Import_Signals_From_C3D_File

This command imports signals from a C3D file into the Active File.

Merge_Aurora_Files

Not Available in Visual3Dv5:

Import_FSV_Files

The FSV/TSV file formats were originally developed by Manfred Berger from Innovision Systems and are currently used by Qualisys and Innovision

Import_Analog_Signals_From_Fsv_File

Importing ANALOG signals stored in an fsv file into an existing c3d file.

File_Save/Export

File_Save

Save the current Workspace to the active CMO file.

File_Save_As

Save the current Workspace to a new CMO file.

Export_3D_Animation_To_Image

Exporting a snapshot of the animation viewer to a file on disk.

Export_C3DFile

Export one or more C3D files from the Workspace

Export_Polygon_C3DFile

Export a file from the Workspace to a C3D file suitable for Vicon's Polygon program
