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.
When dealing with vector-based calculations between segments in biomechanics, understanding resolution coordinate systems is essential. Differing from Cardan Sequences and Euler Sequences, using a resolution coordinate system uses all the axes in the chosen segment. In this tutorial, we explain how these biomechanical principles apply to Visual3D.
When dealing with vector-based calculations in Compute Model Based Data, segment coordinate systems are important to apply correctly. In this tutorial, we explain how to use different segment coordinate systems to obtain your data defined in exactly the way you want.
As two segments rotate with respect to each other, the more complex the motion, the more challenging it is to describe mathematically. In biomechanics, defining the rotations is key to understanding the meaning of the data. One method is to use Cardan Sequences; however, in this tutorial, we explain what Euler Sequences are, and how they are used to calculate rotaions between segments.
Calculating rotational data between two objects in space can be mathematically challenging, especially if those bodies are moving with respect to each other. In biomechanics, we regularly need to perform calculations between segments, and one of the ways we do that is by using Cardan Sequences. In this tutorial, we explain what they are.
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.
Joint moment is one of the most common biomechanical values to be calculated and be used for evaluation of a subject’s performance or condition. In this tutorial, we focus on how the data is calculated depending on which resolution coordinate system or Cardan sequence is used.
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.
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.
Joint force data is a key biomechanical calculation that is easily facilitated in Visual3D. In this tutorial, we explore the meaning of the joint force data in terms of the reference coordinate system. There are many options available, and understanding how these may impact the data you are looking at could help you decide which to choose.
