A set of C++ template classes for doing various types of interpolations on data with any number of dimensions. You can feed the system an arbitrary number of data (data can be simple types like float, int or complex types like structs, classes), then resample at any resolution, or ask for the value at any percentage along the data - or just draw it - including splines in 3D.
This is useful for creating and drawing splines (in any dimensions), or creating smooth animation paths from keyframes (again, in any dimensions).

Made with openFrameworks.
