Visual3D Basics Unit 2 – Chapter 5 – Ankle joint angle offset
Due to the anatomy of the foot, and the relationship between its coordinate system and that of the shank, the joint angle of the ankle is subject to an offset. There are many ways to solve this discrepancy, and in this video we show you a very simple method to get you started.

Joint Velocity
Joint velocity is often used in biomechanics to understand the kinematics between body segments. However, it is not quite as simple to interpret as just taking the first derivative of joint angle. There are several factors to consider, including understanding resolution coordinate systems, so we used this tutorial to highlight what joint velocity is.
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.
Ankle Angle
The complexity of joint angle calculations is made all the more challenging when the joint in question is the ankle. In this tutorial, we discuss why the ankle is complex, and some of the methods to calculate it with reasonable results.
Compute Model Based Data: Joint Angle
The joint angle calculation in Visual3D is a feature of Compute Model Based Data. In this tutorial, we show you how to use both joint angle and helical angle functions to calculate the angle between two segments.
Landmark definition: segment
This tutorial shows you how to define a landmark using the coordinate system of an entire segment. This can be useful when definition markers might become occluded or when the landmark doesn’t correspond to existing points.
