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.
