Compute Model Based Data: Segment Center of Gravity, Proximal Joint, and Distal Joint

One of the key features of Visual3D is the ability to track landmarks accurately. However, as you build your pipelines, you may be interested in knowing the relative position of a point on a segment. In this tutorial, we show you how to use Compute Model Based Data to obtain the coordinates of the center of gravity, proximal joint, and distal joint of a segment. We also show you how to do this with respect to another segment, and show you some tricks by creating virtual segments in your biomechanical model.

Compute Model Based Data: Joint Power

A common but misunderstood biomechanical calculation is joint power. As a feature in Compute Model Based Dataj we have scientifically validated methods to obtain it. However, it is important to understand that both of these model based items are to calculate scalar values. In this tutorial, we explore how to use Joint_Power and Joint_Power_Scalar and explain the difference between them.

Compute Model Based Data: Joint Velocity

The features in Compute Model Based Dataj offer a lot of scientifically validated calculations. However, it is also important to understand how to apply them. When it comes to joint velocity, it is no different, so in this tutorial, we explain how to set up the command to get the data you want.

Using Cardan Sequences

Performing 3D calculations between segments is mathematically complex. When those segments are also moving, setting up those calculations is critical to understanding what your data means. One of the methods in Visual3D to obtain rotational data is to use Cardan Sequences. In this tutorial, we show you how to use Cardan Sequences in Compute Model Based Data and how the data changes based on your choices. We also show you the use of Euler Sequences, which in Visual3D are listed in the Cardan Sequence menu.

Compute Model Based Data: Joint Moment

A properly built a biomechanical model in Visual3D is a very powerful tool, one of the advantages is the ability to perform calculations through Compute Model Based Data. In this tutorial, we show you how to calculate the joint moments, and highlight the difference between using a resolution coordinate system or a Cardan sequence.

Compute Model Based Data: Joint Force

If you have already built a biomechanical model in Visual3D, you can use it to perform biomechanical calculations through Compute Model Based Data. In this tutorial, we show you how to calculate the joint forces, and highlight the difference between using a segment coordinate system or a Cardan sequence.

Compute Model Based Data: GRF Data

Although your force plata data is most likely already synchronized with your motion capture data, in Visual3D, you can recalculate your data to make it easier to interpret based on the coordinate system that is most convenient for you.

Compute Model Based Data: COP Path

Center of pressure is a key historically reported parameter in biomechanics. In this tutorial, we show you how to use the Compute Model Based Data function to calculate the center of pressure path and how to tweak the pipeline command in order to get exactly what you want from your data.

Compute Model Based Data: Joint Velocity & Acceleration

Joint kinematics are a staple element of motion capture biomechanics reporting. In this tutorial, we show you how to use the Compute Model Based Data function to calculate joint velocity and acceleration.

Compute Model Based Data: Joint Rotation

Calculating the joint angle is a key contribution to biomechanics by the Compute Model Based Data feature. However, the rotation between two segments is very complex, and a simple joint angle calculation may not be sufficient to describe the motion. In this tutorial, we show you how to use the joint rotation fuction.
