The IvTune graphical utility is the definitive tool for prototyping and tuning 3D applications. Pluggable in any Open Inventor application, IvTune presents synchronized views of the scene graph: a 3D View, a Tree View, a node overview window, a field editor and a field watch. This allows for fast tuning and debugging at run time, and ideally complements the numerous code examples provided with Open Inventor for quick learning.
