This is an advanced 3D data translation, rendering & scene composition software for Microsoft Windows and includes all the functionality of PolyTrans inside NuGraf (PolyTrans is a subset of NuGraf). With its support of virtually every 2D and 3D file format you will need no other tool to visualize 3D models and translate them to your format of choice.
