SceneViewer - 3d editor and viewer for Inventor scenes

SceneViewer [-e env_file] [file]

SceneViewer is a program for viewing and interacting with Inventor scene graph files (the SGI 3D file format standard). SceneViewer was written to demonstrate Inventor features, and serves as the basis for the IRIS Explorer Render Module.

When SceneViewer is run, a window appears containing the Inventor examiner viewer and a menu bar. The viewer allows the user to interactively change the view of the scene through direct manipulation, or indirect slider and push button controls. The menu bar contains the following menus:

File

This menu supports file reading and writing, and launches a dialog for printing to a printer or to PostScript file.

Edit

This menu enables copy and paste of 3D data, selecting all objects, and deleting the currently selected objects.

Viewing

This menu controls viewing options. It allows different viewing paradigms to be employed: the examiner viewer which provides a virtual trackball interface, the fly-through viewer for traveling through expansive data sets, the walk viewer for architectural walk-throughs, and the plane viewer for orthographic projections. The menu also enables different types of transparency, fog effects, antialiasing, and background color controls.

Selection

This menu allows the different selection policies to be demonstrated. A selection policy determines how objects get added and removed from the collection of selected objects.

Editors

This menu launches the material editor and transform sliders. An object must be selected for the menu to be active.

Manips

This menu allows different manipulators to act on the current selection, including the trackball, handle box, jack, center ball, and transform box. Manipulators can also be turned off, in which case selected objects are surrounded with a red wireframe box highlight.

Lights

This menu allows directional, point, and spot lights to be created and edited. It also allows lights to be turned on and off.

For more information on how to use the viewers and editors employed by the scene viewer, please see SceneViewer's runtime help cards.

Note that the source code to SceneViewer comes with the Open Inventor 3d Toolkit.

The following command line options are allowed:

-e env_file

Read the passed environment file, and use the lights, camera, and environment settings found there.
