Description:

The Open Inventor 3D Toolkit is an object-oriented toolkit that
simplifies and abstracts the task of writing graphics programming into
a set of easy to use objects. These objects range from low-level
data-centered objects such as Sphere, Camera, Material, Light, and
Group, to high-level application-level objects such as Walk Viewer and
Material Editor. The foundation concept in Inventor is the "scene
database" which defines the objects to be used in an application. When
using Inventor, a programmer creates, edits, and composes these
objects into hierarchical 3D scene graphs (i.e. database). A variety
of fundamental application tasks such as rendering, picking, event
handling, and file reading/writing are built-in operations of all
objects in the database and thus are simple to invoke.
