This software library implements simplicial interpolation as described in the article "Interpolated Mappings for Musical Instruments," Organised Sound 7(2), Cambridge University Press.

Download the C++ source code,
and uncompress it.
"make" builds and runs an interactive OpenGL Linux demo
(screenshot shown).
It also compiles and runs on OS X 10.3.9.
Update, March 2009: In the test case, replaced "tail +2" with sed. Now runs on Ubuntu Hardy Heron.
To tweak, start at the bottom of si.c++. Call evalInteractive() for the OpenGL demo; alternatively, call evalAutomatic() to exercise the interpolator on randomly generated data. Constants d and e defined at the top of si.h determine the dimensions of the domain and range spaces.
