The core geometry library vgl is intended to provide an environment for geometric primitives, both in cartesian and homogeneous representations, and for both 2D and 3D.

This includes classes for

• Points, lines and planes.
• 2D conics.
• Rectangular bounding boxes.
• Polygons.
• Direction vectors.
• Region scan iterators.

In addition, the vgl-algo library contains functions to perform elementary geometric operations like intersecting two lines, finding the nearest point on a line or a conic, computing the cross ratio of four points, lines or planes.

For convenience, this functionality is put in a "name space", separate for 2D and 3D, and separate for cartesian and homogeneous representations.

All representation classes are templated on the computational numeric type.
