Major website update

[felixchenier]

The website has been updated and now features a whole free electronic book entitled "Biomechanical Analysis using Python and Kinetics Toolkit".

Since Kinetics Toolkit is a programming library and programming is hard for newcomers, this book covers everything from the essentials of Python programming (including how to install a working environment), to complex analyses such as 3D geometry and kinematic reconstruction. The following concepts are covered, with biomechanics-related examples and exercises based on real, downloadable data:

• The Python programming language, including arithmetics, variables, numbers, strings, functions, conditions, lists, loops and dictionaries;
• Matplotlib, to generate print-quality graphics and to analyze curves interactively;
• NumPy basics, including n-dimensional arrays, arithmetics, trigonometry, infinity/nan, statistical functions, comparisons, logical operators, indexing, slicing and filtering arrays;
• TimeSeries analysis, including data, time and event management, time-domain and frequency-domain noise filtering, and cycle management;
• File management, including reading/writing C3D, CSV and any file supported by Pandas;
• Rigid body geometry, including manipulation of series of points, vectors, frames and homogeneous transforms, coordinate system changes, and 3D angle extraction;
• Interactive visualization of 3D markers and rigid bodies;
• Kinematic operations such as reconstructing occluded, removed or probed markers.
