Tutorial: Creating Landmarks

This Tutorial page lists the many different ways to create Landmarks within Visual3D.

Landmark Type 1

Creating a landmark at the end of a segment that is tracked with the segment.

Landmark Type 2

Projecting a marker onto a plane.

Landmark Type 3

Projecting a marker onto one of the principal planes of the laboratory.

Landmark Type 4

Projecting a marker onto a line.

Landmark Type 5

Creating a landmark that defines the location of a segment endpoint relative to 3 tracking markers (or landmarks).

Landmark Type 6

Create a landmark relative to a Segment Coordinate System.

Landmark Type 7

Create a landmark relative to the Global Coordinate System (Lab).

Automatically Created Hip Landmarks

Landmarks defining the location of the hip joint center automatically created when the CODA or Helen Hayes Pelvis segment is created.

Functional Joint Landmarks

Calculation of a functional joint requires movement of one segment relative to another segment. The algorithm searches for a point (or for a one degree of freedom joint, an axis) that is stationary relative to the 2 segments (or 2 sets of markers).

Tutorial: Digitizing Pointer Post Processing

Identifying anatomical landmarks without having to place motion capture markers at the location using a digitizing pointer.
