PySide is a binding to the Qt cross-platform application framework. This
package contains helper classes that integrate Open Inventor / Coin3D
into PySide based applications, namely:
- QIVWidget: Viewport widget for rendering and interacting with scene
graphs.
- QInspectorWidget: Scene graph inspector showing the scene structure in
a tree view and the fields of a node in a table view.
Extension libraries that provide additional scene objects can be loaded
by defining the IV_LIBS environment variable, which can contain names of
dynamically loadable libraries separated by a semicolon. Those libraries
need to define a function called initAllClasses() that register all scene
objects in the global database.
