What's New in v6.03

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

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

Interface Changes

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

Event Creation

New/Modified Commands (click to expand)

Event_Define_Event_Sequence - 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_Global_Maximum
• Event_Global_Minimum
• Event_Maximum
• Event_Minimum

Event Management

New/Modified Commands (click to expand)

Event_Sequence_Delete - 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 (click to expand)

Create_Text_Data - 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 (click to expand)

FP_Auto_Baseline - 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.

1. Put_To_Matlab
2. Get_From_Matlab
3. 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 (click to expand)

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:

• Metric_Maximum
• Metric_Minimum
• Metric_Time_of_Maximum_from_Event
• Metric_Time_of_Minimum_from_Event
• Metric_Time_of_Global_Maximum_from_Event
• Metric_Time_of_Global_Minimum_from_Event

Metric_Compute_Confidence_Ellipse
