Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
Announcement text: ----------------------------------------------------------------------
Package additions: Two new modules have been created: utils and tkz.
The utils module provides a collection of general-purpose utility
functions. These functions are designed to support common tasks
such as numerical rounding, type checking, floating-point comparisons,
and table operations.
utils.parse_point, utils.format_number, utils.format_coord,
utils.format_point, utils.checknumber,utils.almost_equal,utils.wlog
The tkz module provides a collection of auxiliary functions.
These functions are not strictly required but serve to simplify many
geometric operations and shorten code. Their use depends on the context,
but in the spirit of the package, it's preferable to use objects.
Most of the following functions already existed, but are now used
with the tkz prefix. This is the case for length and midpoint.
Others are new, such as tkz.solve, which solves equations up to degree 3.
Note also the tkz.angle_between_vectors function, which determines
the angle between two vectors.
tkz.solve, tkz.solve_linear_system, tkz.midpoint, tkz.length,
tkz.round, tkz.length, tkz.midpoint, tkz.midpoints, tkz.is_linear,
tkz.is_ortho, tkz.bisector, tkz.bisector, tkz.altitude, tkz.get_angle,
tkz.angle_normalize, tkz.barycenter, tkz.dot_product, tkz.nb_dec,
tkz.epsilon, tkz.dc, tkz.phi, tkz.invphi, tkz.sqrtphi,
tkz.reset_defaults(), tkz.set_nb_dec(n).
The path class has been enriched with the ability to create paths
directly using conics and triangles. The methods have been rewritten
and now use the add_point method.
In order to make the best use of paths, I've added macros that allow
you to create them using TikZ. There are now : \tkzDrawPointsFromPath,
\tkzGetPointsFromPath, \tkzDrawCirclesFromPaths, \tkzDrawSegmentsFromPaths
New mathematical features include the creation of the Poncelet point
for the triangle class (poncelet_point). This method also exists for
the quadrilateral class.
The orthopole method has been added to the triangle class.
The macro \tkzDN has become \tkzPN alias of \tkzPrintNumber.
The method of the circle class, orthogonal_through, has been
corrected and rewritten.
Aliases with more evocative names are appearing:
line.parallel_from alias of line.ll_from line.orthogonal_from alias
of line.ortho_from \tkzDrawPath alias of \tkzDrawCoordinates
\tkzPN alias of \tkzPrintNumber
The \tkzEraseLuaObj macro deletes a lua object.
Documentation
The Cheat_sheet section has been removed. You can find it on my site.
Two sections have been added: "maths tools" and "tkz".
Some examples have been added: Archimedean spiral, Poncelet point,
Orthopole, examples for "paths".
