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.
Landmark definition: 3 points
This tutorial shows how to define a landmark in 3D space in Visual3D. When you use three points for reference, you can specify offsets along the X, Y, and Z axes, giving you full control over where in virtual space to place your landmark.
Static vs dynamic
This tutorial explores the differences between static and dynamic trials and how they are used in Visual3D. A static trial is used to define the biomechanical model that is applied to dynamic recordings.
Landmark definition: 2 points
This tutorial shows how to track a point of interest located on a line between two other points. This is useful for tracking points that cannot be directly defined by markers, such as the knee joint center.
Landmark definition: 1 point
Not all points of interest for motion capture can be tracked by markers. This video explains how landmarks solve this problem and shows how to use Visual3D to define a landmark using a single point.
