We present a novel mathematically faithful object oriented design for a general purpose isogeometric library and introduce a high quality open source implementation of it, igatools (http://code.google.com/p/igatools). The library uses advanced programming techniques and supports dimension independent programming. It includes support for manifolds and isogeometric elements of the h-div and h-curl type. To illustrate the exibility and power of the library we present some example applications including surfaces, uid and elasticity.
