ecl_geometry Documentation

*Any tools relating to mathematical geometry.
Primarily featuring polynomials and interpolations.*

- Homepage: http://wiki.ros.org/ecl_geometry

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: @code #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; @endcode You will also need to link to <i>-lecl_geometry</i>.

Refer to the class api/guide for each component. - @ref anglesGuide "Angles" - c++ style wrapper for angles (radians) and unit conversions (deg<->rad). - @ref ecl::CartesianPoint "Cartesian Points" - generic and specialised representations for cartesian points. - @ref ecl::Pose2D "Pose2D" - extends eigen's geometry transforms with a 2d specialised version. - @ref polynomialsGeometry "Polynomials" - polynomial functions and two-point interpolations. - @ref splinesGeometry "Splines" - generating various splines and interpolating over a set of data.
