%description
Tools implementing an automated version of the graphic double integration
technique (GDI) for volume implementation, and some other related
utilities for paleontological image-analysis. GDI was first employed by
Jerison (1973) <ISBN:9780323141086> and Hurlburt (1999)
<doi:10.1080/02724634.1999.10011145> and is primarily used for volume or
mass estimation of (extinct) animals. The package 'gdi' aims to make this
technique as convenient and versatile as possible. The core functions of
'gdi' provide utilities for automatically measuring diameters from digital
silhouettes provided as image files and calculating volume via graphic
double integration with simple elliptical, superelliptical (following
Motani 2001 <doi:10.1666/0094-8373(2001)027%%3C0735:EBMFST%%3E2.0.CO;2>) or
complex cross-sectional models. Additionally, the package provides
functions for estimating the center of mass position (COM), the moment of
inertia (I) for 3D shapes and the second moment of area (Ix, Iy, Iz) of 2D
cross-sections, as well as for visualization of results.
