Compute Model Based Data: Segment Residual
The segment residual is a very useful tool to evaluate the quality of the fit of a segment’s tracking to the markers used for it. Compute Model Based Data gives the option to obtain the segment residual for any segment included in the biomechanical model.
Segment Residual
An often overlooked fact in motion capture, is that segment position is based on the best estimation from marker locations. Of course, due to soft tissue artifacts, the fit of the segment tracking may change throughout the motion. Although, this may not be the type of data you would report to patients or subjects, it could be a valuable piece of information to evaluate the quality of your data.

Visual3D Basics Unit 7 – Chapter 3 – Adding custom images
For clarity, generic images aren’t always the best reference. Since Visual3D offers visualization of segments, we devote this chapter to showing how to choose and save an image of a subject-specific motion. We also demonstrate how to insert those same images into a report next to a graph.
