Welcome to Visual3D™, the most advanced 3D analysis software available for biomechanical motion analysis (kinematics and kinetics). Proven in scientific and clinical research labs world-wide, Visual3D™ is the world's leading software solution for rigorous and accurate 3D motion analysis.
Visual3D™ can process data from nearly any type of motion capture system using the industry standard C3D format. It also processes any synchronized analog signals such as forceplates, load cells, instrumented treadmills, and EMG. Visual3D™ computes the biomechanics based on Newtonian dynamics, and can do it in real-time.
Visual3D™ has been proven in multiple fields such as:
Gait analysis
Sports injury and performance assessments
Physical Rehabilitation
Ergonomics
Neuroscience
Animal studies
Entertainment
Industrial Processes
And many more...

Visual3D™ has the ability to perform kinematic and/or kinetic calculations on non-standard marker configurations such as those used routinely by many laboratories.
Visual3D™ will accommodate legacy data that a laboratory may have archived that was collected using a non-standard marker configuration.
Visual3D™ provides a very powerful and flexible model construction capabilities using the Hybrid Model type.
The hybrid model allows for models to be constructed using different segment types methodologies (ie; using a Helen Hayes pelvis with a Visual3D™ 6 degree of freedom lower body).
The Visual3D™ segment type is expanded in the hybrid model to allow for user defined custom models.
The hybrid model contains very powerful and advanced landmark creation methods.
Additionally, Visual3D™ supports several other legacy model types, including derived models.
At the core of Visual3D™ is the development of a flexible biomechanical modeling tool that can be used to define an unrestricted number of rigid segments and link them together in a cohesive fashion. Each segment is treated individually and is allowed to exist anywhere in space. Its movement is not constrained in any way. Due to this lack of constraints, analysis of joint motion is done based solely on the relative motion of the segments as detected by the motion-tracking apparatus.
Dynamic modeling can be supported using functional joint center (and rotation) calculations. No attempt is made to constrain, say, the knee joint to bend only one way. Because of this, you specify a model in Visual3D™ by describing all the segments and you don’t have to say anything about joints. With Visual3D™ a joint is simply the place where the distal end of one segment meets the proximal end of another segment.
Visual3D also supports traditional modeling approaches such as Helen Hayes/Newington, CODA, and others.
The Visual3D model builder allows the use of custom and minimal marker sets.
Marker clusters are supported have been shown to be one of the most accurate non-surgically implanted ways of reducing soft tissue artifacts. Other ways of addressing STA errors (such as for hip axial rotations) are also supported.
One of the guiding principles behind the design of Visual3D™ is that your original data is sacrosanct – and must never be changed or modified. This protects the researcher and allows analysis results to be reproduced at any time.
Data is copied into the Visual3D™ workspace, and Plug-ins that do data conversions only read the original data.
All processed data can be reconstructed. Visual3D contains the entire history of processing steps to allows the precise re-processing of the signals so you can go back and make changes and if necessary re-run your analysis.
The visualization of motion data can be shown as skeletons, mannequins or user-defined animations that have been imported from external software. Ground reaction forces from force plates can be shown as vector arrows and force butterflys. EMG signals can also be visualized. The presentation of synchronized video is also possible within Visual3D.
Visual3D provides straightforward reports that are used to produce and interpret movement sequences, including a standard analysis report that can be generated with a minimum of input using automated processing scripts. At the same time, more advanced users will be able to access a more flexible analysis for less common applications (including unique patient populations) and to customize the report format.
The Pipeline processor provides access to the core of Visual3D™ functionality.
The Pipeline allows a set of Visual3D™ commands to be processed in sequence.
It provides a command line interface into all of Visual3D™'s functions. The Pipeline has the ability to manage files, define events, execute signal processing computations, create and edit modes, create and modify reports, and generated statistics. Edit boxes are usually provided for configuring each process step.
A pipeline can be used to define the processing steps for a given experimental data analysis protocol. This allows, for example, the director of the laboratory to control the processing that is done by a member of the laboratory. This may be essential for some experimental studies that require that all of the data analysis be performed consistently.
Any pipeline commands can be saved to a text command file. This file may be reloaded later, or combined with other command files to build a more complex pipeline.
Visual3D™ plug-ins integrate seamlessly into Visual3D™ and can be accessed through the pipeline processor.
