• The Package PlanGeom (version 0.04, October 2005, by J. Cortes and F. Bullo) is dedicated to the computation of some basic computational geometric objects, such as intersection between lines, intersections between segments and circles, orthogonal projections onto lines and polygons, etc. The package contains routines to compute various proximity graphs, such as the Delaunay graph, the Gabriel graph, and the Relative Neighborhood graph. The routines have not been optimized for speed.
  The package requires a slightly modified version of the Combinatorica library, available here.

• The Package SpatialGeom (version 0.02, July 2004, by J. Cortes) is dedicated to the computation of some basic computational geometric objects in 3D. The Package LineGeom (Dec 2004, by J. Cortes) has two very basic corresponding tools.

• The Package LieGroups (version 0.8, Jan 2000, by F. Bullo) provides routines to perform some basic differential geometric operations on matrix Lie groups.
