H3DViewer is a browser that previously only was included with the H3D API package. Now it is released as a stand alone application for Windows and OSX.

In H3DViewer X3D scenes with or without H3D content can be loaded and modified at run time through the tree view.

It is also possible for H3DViewer to load plugins which contains custom made H3D nodes. With this distribution a couple of plugins are included to handle graphics and haptics volume rendering, haptic user interface and rigid body physics simulations.

Grab it from the downloads section.
