====== 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).

==== Landmark Type 8 ====

==== 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.
