This group includes various structures and tools used in geometry as well as various supporting classes and utilities.

There are quite a few useful tools also in eigen's geometry module. You can get access to these via the ecl_linear_algebra module.

- angle-axis pairs
- quaternions
- rotation matrices
- transforms

Include the following at the top of any translation unit which requires this library:

#include <ecl/geometry.hpp> // Angles using ecl::Angle; using ecl::wrap_angle; using ecl::degrees_to_radians; using ecl::radians_to_degrees; // Other Objects using ecl::CartesianPoint; using ecl::PascalsTriangle; // Functions that act on functions using ecl::Minimum; using ecl::Maximum; // Functions using ecl::Polynomial; // Also has some typedefs, LinearFunction, CubicPolynomial, QuadraticPoly... using ecl::TensionFunction; // Splines using ecl::SmoothLinearSpline; using ecl::CubicSpline; using ecl::TensionSpline; // Transforms using ecl::Pose2D;

You will also need to link to *-lecl_geometry*.

Refer to the class api/guide for each component.

- Angles - c++ style wrapper for angles (radians) and unit conversions (deg<->rad).
- Cartesian Points - generic and specialised representations for cartesian points.
- Pose2D - extends eigen's geometry transforms with a 2d specialised version.
- Polynomials - polynomial functions and two-point interpolations.
- Splines - generating various splines and interpolating over a set of data.
