Open Inventor is a cross-platform object-oriented 3D toolkit offering a comprehensive solution to interactive graphics programming problems. It presents a programming model based on a 3D scene database that dramatically 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 3D programming capabilities.

Open Inventor:

• is built on top of OpenGL
• defines a standard file format for 3D data interchange
• introduces a simple event model for 3D interaction
• is platform independent
• supports PostScript printing
