I am having trouble exporting a .x3d file in a format which programs that convert .x3d data to VRML data can read.
The error message for one of them is:
Xj3D Version: 1_0
Device found: Mouse-0 Device found: Keyboard-0 Error: Unexpected Exception: Unknown field name: chimera:hither for node: org.web3d.vrml.renderer.ogl.nodes.navigation.OGLViewpoint@1080876 Error: Failed to load file
This is enough of a hassle that we plan to add direct export to VRML97 this summer. In fact, I have yet to find a converter that produces unextended VRML97 . If you get the Xj3D converter to work for you, please let me know. The workaround for the problem you're having is to hand edit the .x3d file and remove the chimera:hither='...' and chimera:yon='...' fields from the Viewpoint tag as well as the <chimera:WindowSize ...> and <chimera:DepthCue ...> tags. Then Xj3D and X3DConv will open the file successfully. The chimera: extensions are legal XML, but Xj3D is not skipping them as it should. I'll file a bug with them.
