The IGUANA Interactive Graphics TOolkit with Examples from CMS and D0

IGUANA（Interactive Graphics for User ANAlysis)is a C++ toolkit for developing graphical user interfaces and high performance 2-D and 3-D graphics applications,such as data browsers and detector and event visualisation programs.The IGUANA strategy is to use freely available software(e.g.Qt,SoQt,OpenInventor,OpenGL,HEPVis)and package and extend it to provide a general-purpose and experiment-independent toolkit.We describe the evaluation and choices of publicly available GUI/graphics software and the additional functionality currently provided by IGUANA.We demonstrate the use of IGUANA with several applications built for CMS and D0.
