Draws a curve through a user-defined set of points, based on the polynomial order specified
The user provides a set of interpolation points, as well as the polynomial degree via a Python interface. The code interactively calculates the control points needed to draw a curve through the provided points using functions in C++ scripts.
This repo also contains various other Python files which plot B-splines in 1D and 2D using shape functions and De Boor’s algorithm.
pybind11 is used as the interface between Python and C++. Functions and classes from C++ are exposed using “bindings”, and these are contained in the folder python/bindings. Once exposed, these C++ functions and classes can be compiled and accessed from Python. Thus, one can take advantage of the efficiency of C++ by writing the computationally demanding functions in C++ while using the user-friendly aspects of Python to input data, as well as plotting and printing.
Note: when compiling on Linux, after running the make command, you must also run make install to copy Python files over to the build folder. On Windows, you must build the install folder for the same aforementioned reasons.
