saynono/ofxMSAInterpolator
C++ openFrameworks addon with a set of 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, then resample at any resolution, or ask for the value at any percentage along the data. Input data can be floats (for 1D splines, Vec2f (for 2D splines), Vec3f (for 3D splines), or even matrices, or custom data types (e.g. biped pose). Demo at www.memo.tv/msainterpolator
