Major v2022.08.1 release

Multisubject support in C3D files using the subject prefix parameters (prefixes are provided by mocap systems).
1. Single subject processing is unaffected by this feature, so prefixes are not necessary for that.
2. Automatically adds subject prefix to marker labels landmarks and segments in Model Templates.
3. Allows multiple subjects in the same movement trial to be processed (identified by the unique prefixes used).
4. Allows multiple static calibration trials to be used for applying to movement trials. Handles each subject separately for computing means, normal data, metrics, etc. when working with the CMZ Library. Previously V3D required 1 subject per CMO/CMZ file.
5. Allows subject tagging in the model to allow setting the active subject tag (in Set_Active_File) which lets pipelines process different types of subjects differently (ie; BATTER, PITCHER, etc. tags, generically applied to any specific subject prefix).
6. Nearly every pipeline command modified to support active subjects and processing subjects separately.
Additional support for markerless data, including model building and processing for Theia3D markerless files.
Bug fixes and performance tweaks throughout.
RT Plugin updates for compatibility with manufacturer software updates
Numerous usability and UI enhancements throughout.

Functional Changes

Visual3D v6 - older updates

Visual3D v6 contains more changes than any other Visual3D release. The new file format (CMZ) saves link-model data so large files will open much faster, allows for model animation while viewing the library, and allows for model based access for calculations across the library of .cmz files. With the new 64 bit version of Visual3D along with multithreading, processing time will be significantly reduced.

NOTE: plug-in modules, real-time, and MatLab support are different in 32 and 64 bit versions. There are separate plugins for 32 and 64 bit versions of Visual3D, you must download the correct plugins for the version you install. The 64-bit version will allow for better use of memory, and supports some later features of MatLab. Some older plugins have not been ported to 64 bit, so if you do not find a plugin you were previously using on 64 bit, download and install the 32 bit version to use the older plugin.

Although there have been many enhancements to Visual3D, below is an outline of just a few of the new features and new commands.Visual3D is continuously updated with new features and enhancements so keeping up with the latest download you will be sure to have access to the latest bug fixes, new features and enhancements.

Performance Changes

A 64 Bit version of Visual3D
This will resolve issues for users with large CMO's that often hit the “Out of Memory” error
New CMZ file format for saving files
Faster file open times
Performance enhancements for faster model building and IK computations times
Multithreading
Library Enhancements:
1. Segment animation
2. Ability to create new Link Model Based items
3. Incorporate CalTester+ force platform corner location into Visual3D
Inverse Kinematics Enhancements:
1. Motion Constraints
2. Boundary Conditions
3. C3D files are processed simultaneously for much faster processing times

Interface Changes

Easier report editing with tabbed design. More changes currently in the works for future releases
Support for 4K monitors
Many real time streaming enhancements and features for RT biofeedback
Enhanced graphs with many improvements such as smoother lines and better scaling
New interface enhancements and toolbar icons
Will also fix print to PDF issues for some users when printing dotted lines
Modeless dialog capability for using common dialogs while working in other dialogs simultaneously
Event Sequence definitions to simplify specifying and modification of ranges throughout Visual3D
Color coded text editor for the pipeline
The Query function was added to the Reports
Copy Landmark feature

Event Creation

New/Modified Commands

Event_Define_Event_Sequence
1. Event Sequences can be used to define sequences of events such as right stance, or the first 20 cycles. Event sequences can then be used in place of events in subsequent processing.
When defining maximums & minimums in Visual3D, a new parameter was added which allows users to define the threshold. This parameter was added for the following commands:

Event Management

New/Modified Commands

Event_Sequence_Delete
1. Event Sequences can be used to define sequences of events such as right stance, or the first 20 cycles. Event sequences can then be used in place of events in subsequent processing.

File Management

New/Modified Commands

Create_Text_Data
1. Text Data is a new “Signal Type” which was added to the data tree. This allows users to define strings in the CMO file. For example, a signal can be created called “Affected_Side” and the user can specify the Left or Right side here. Files can be queried using text data as well.

Force

New/Modified Commands

FP_Auto_Baseline
1. This command can be used to automatically determines the zero period and the force platform minimum value. This is especially helpful for treadmill trials when it is difficult to determine a period when the treadmill is unloaded and for front to back treadmills where a high force platform minimum value can cause discontinuity in the force signal.
Locate_Force_Platform_Corners
Modify_One_Force_Platform
Reset_Segment_Assignment_To_Force_And_COP

Matlab

64 bit Matlab support.

Put_To_Matlab
Get_From_Matlab
Eval_In_Matlab

Certain Matlab commands are only available in the 64 bit version. Matlab no longer supports 32 bit installations, so legacy support will only be available in the 32 bit version of Visual3D.

Metric

New/Modified Commands

When defining maximums & minimums in Visual3D, a new parameter was added which allows users to define the threshold. This parameter was added for the following commands:

Model Based Data Computation

New/Modified Commands

Compute_Model_Based_Data parameters with added treadmill velocities

Pipeline Control

New/Modified Commands

RT and Post Processing Biofeedback

New/Modified Commands

Animated_Line
Animated_Sphere
Animated_Surface
Animated_PolyLine
Modify_RTGraph_Settings

Reports/Interactive Graphs

New/Modified Commands

Folder Encryption

New/Modified Commands

Other

New/Modified Commands

Open_Edit_Dialogs
Map_Segment_Color_To_Signal_Value
