A series exploring the many options available in Visual3D and showing how to use the tools to get the most out of your data.

Within Visual3D, since you can automate your data processing, there are many options of filters. In this tutorial, we show you some of the more advanced options by highlighting the DFT filter, Teager Kaiser Energy, FFT, Bin Integrate, and GVCSPL pipeline commands.
Performing mathematical operations on your signals in Visual3D is a standard part of data processing. You will – most likely – have a need to add, subtract, multiply by, or divide by a constant. In this tutorial, we show you how to using the dedicated pipeline commands to perform these operations as part of your automated data processing.
Signal manipulation to obtain the results you are working for is a key part of using Visual3D. In this tutorial we focus on math between signals. We show you how to set up these operations directly in your pipeline using dedicated commands.
Understanding kinematics in biomechanics is fundamental to analyzing human motion. Part of kinematics is being able to use derivatives and integrals to obtain position, velocity, and acceleration. In this tutorial, we show you how to use the pipeline commands for derivatives and integrals.
If you need a custom calculation, that there isn’t a dedicated pipeline command for, you will probably want to use Evaluate Expression. This is a very useful command that gives many options. In this tutorial, we talk about the basics of Evaluate Expression by simply adding two signals to illustrate performing simple math in this pipeline command.
Developing pipelines for a biomechanical analysis will often require specific calculations. In this tutorial we show you how to use three dedicated commands to calculate the square root and the magnitude and to rectify a signal.
Establishing timing parameters for biomechanics trials allows you to compare data. One of the most common types of motion to analyze is gait, and in this tutorial we focus on how to use the automatic gait events pipeline command.
In order to obtain full control of your data, identifying events gives you a way to refer to points in the acquired motion and potentially a way to time normalize as well. Finding the global maximum or minimum of a signal can be a very useful tool to identify specific events. In this tutorial, we show you how to use the dedicated pipeline commands for event global maximum and minimum.
A more general way to identify peaks and valleys in your data is to use the Event Maximum and Event Minimum pipeline commands. Although similar, these commands give more options compared to the Global Event Maximum and Minimum methods. This tutorial will show you how to use these commands, and set them up correctly.
There may be occasions that you need to specify the exact frame or moment in time to set an event. In this tutorial, we show you how to use the event explicit command to create an event, and give an example of how to use it in a pipeline.
