Inertia X and Y axes require that the Extrinsic Inertia Results box be checked in the Data Col-
lection property.
Object Definition
Inertia X-Axis The moment of inertia about the X-axis of the Tool
coordinate system.
Inertia Y-Axis The moment of inertia about the Y-axis of the Tool
coordinate system.
The intrinsic moments of inertia measure the iner-
tial resistance of the blob to rotation about its prin-
cipal axes. Because their orientation depends on
the coordinate system in which the blob is rep-
resented, the principal axes, major and minor, are
defined in the section on extrinsic blob properties.
Rotation of the Principal Axes
The counterclockwise angle between the X-axis of a selected coordinate system and the
major axis.
Object Definition
Principal Axes Rotation The angle of axis of the smallest moment of iner-
tia with respect to the X-axis of the selected coor-
dinate system.
Intrinsic Bounding Box Results
The smallest rectangle enclosing the blob. The width and length of this box define the minor
axis and the major axis. Extents measure the distance between a blob's center of mass and
the four sides of the bounding box.
