Additional Java resource: Xj3D is able to render scenes to an image using off-screen rendering.  In the X3D examples, each of the thumbnails for directory summaries and each of the Viewpoint images generated for the documentation HTML are created this way.

     X3D Example Archives: X3D for Web Authors, Chapter 02 - Geometry Primitives

     http://x3dgraphics.com/examples/X3dForWebAuthors/Chapter02-GeometryPrimitives/Box.html
     Viewpoint description='Book View'
     http://x3dgraphics.com/examples/X3dForWebAuthors/Chapter02-GeometryPrimitives/_viewpoints/Box.x3d._VP_Book_View.png

The images are also checked into version control, providing a 'visual diff' when rendering changes occur.  Helpful unit test.

Example Java invocation for Xj3D can be found in each respective archive's build.xml file under targets

     processScenes.captureViewpointImages
     processScenes.captureThumbnailImages

all the best, Don
