`longbone_Analysis`	A wrapper for batch processing with longbone_*Geometry functions.
`longbone_CustomGeometry`	This function analyzes the cross-sectional geometry of an intact humerus, ulna, femur, or tibia bone along its longitudinal axis at custom intervals.
`longbone_FragmentGeometry`	This function analyzes the cross-sectional geometry of any diaphyseal long bone fragment at custom intervals defined by user defined points on the bone's surface.
`longbone_Geometry`	This function analyzes the cross-sectional geometry of an intact humerus, ulna, femur, or tibia bone at 20%, 35%, 50%, 65% and 80% along the bone's maximum length.
`longbone_Registration`	Determine long bone type and register initial alignment points.
`simple_polygon3D`	This function takes the 3D coordinates of a planar cross section along with with its normal and calculates some of its geometric properties such as cross sectional area, perimeter and principal second moments of area.

mesh3D

`longbone_maxDistance`	Calculate the maximum distance of a long bone 3D model.
`longbone_Scaling`	Scale triangular meshes stored in Wavefront OBJ format.
`meshArea`	Compute the surface area of a triangular mesh based on itsvertices and faces provided as input arguments.
`meshBarycenter`	Compute the 3D coordinates of the polygon barycenter of a triangular 3D Mesh based on its vertices and faces provided as input arguments.
`meshSection`	Compute the sectioning points of triangular 3D mesh.
`read_MeshlabPoints`	Read 3D coordinates from a MeshLab PickedPoints file.
`write_MeshlabPoints`	Write 3D coordinates in a MeshLab PickedPoints file.
`readObj`	This function reads a triangular 3D Mesh from Wavefront OBJ file and returns its elements into a variable number of output arguments.
`renameObj`	Rename an OBJ file containing a pure triangular mesh in Wavefront 3D model file format and its associated material library and texture map files.
`writeObj`	This function saves a triangular 3D Mesh in a Wavefront OBJ file format according to its elements provided as input arguments.

Plot

`inspect_CSG`	Batch inspect the CSG properties of previously analyzed long bones.
`visualize_CrossSections`	Plot cross sectional contours and their CSG properties for a given sample.

Utilities
