Open Inventor is an object-oriented 3D toolkit developed by Silicon Graphics (SGI) offering a comprehensive solution to interactive graphics programming problems. It presents a programming model based on a 3D scene graph that simplifies graphics programming.
It includes a rich set of objects such as cubes, polygons, text, materials, cameras, lights, trackballs, handle boxes, 3D viewers, and editors that speed up programming time and extend your 3D programming capabilities. Furthermore, it is easily extendible to add new functionality.
Most of the visualization modules of MeVisLab make use of Open Inventor.
