X3D-Edit 3.1 is a graphics file editor for Extensible 3D (X3D) that enables simple error-free editing, authoring and validation of X3D or VRML scene-graph files. Context-sensitive tooltips provide concise summaries of each VRML node and attribute. These tooltips simplify authoring and improve understanding for novice and expert users alike.

X3D-Edit Auto Installer is available online for various operating systems (Windows, Mac, Linux, Solaris and other Unix).

X3D-Edit 3.1 uses the X3D 3.1 tagset defined by the X3D 3.1 Document Type Definition (DTD) in combination with Sun's Java, IBM's Xeena XML editor, and editor profile configuration files.

See X3D Help for further X3D resources.


X3D-Edit 3.1 implements the Extensible 3D (X3D) tagset for the next-generation Virtual Reality Modeling Language (VRML 200x). X3D-Edit also exercises various X3D graphics rendering and translation implementations.

Latest updates of software and examples: see build.date.X3D-Edit.txt.

Version 3.1 matches X3D 3.0 International Specification (Summer 2004) and adding components from X3D Amendment 1 (Winter 2005).

Completed v3.1 components:

Also ongoing: testing X3D Schema (x3d-3.1.xsd) against several thousand X3D examples using a project file for XML Spy.

Functional improvements:

Education: We're using X3D-Edit to teach a VRML/X3D course. Reducing content bugs and eliminating the syntax idiosyncracies of VRML really helps! Using the beta version January-March 2000, we got through the material in the VRML 2.0 Sourcebook one week faster than in previous versions of this course. We are making similarly excellent progress using the current version of X3D-Edit. X3D versions of sourcebook examples (270 total!) are available on the X3D Examples for Vrml 2.0 Sourcebook site.

Suggestions and improvements regarding X3D-Edit installation/usability are welcome. Discussion of this tool occurs on the www-vrml mail list.

Additional instructions for Mac are available in README.X3D-Edit.Mac.txt thanks to the ever mac-nificent Steve Guynup (guynups@gra.com)

Installation Setup

You will need to be logged in with administrator permissions to perform some of these installations.

Recommended installation: AutoInstaller. X3D-Edit AutoInstaller for various operating systems (Windows, Mac, Linux, Unix/Solaris).

Once installed, and once you have a VRML plugin (step 1 which follows), you can update to new revisions by skipping ahead to step 7 and simply extracting the updates on top.

If you prefer to install X3D-Edit manually, follow steps 1-6 instead of using the autoinstaller.

  1. Install one of these free Virtual Reality Modeling Language (VRML) plugins in your web browsers. These plugins can work with any combination of Netscape and Internet Explorer.
    To see if your VRML-browser installation worked, try viewing the HelloWorld.wrl example scene.
  2. Install Java using one of the online distributions. (Java is needed in order to run the Xeena tool.) When installing, you will need to acknowledge the nonrestrictive Java license.

    You might save a download if Java is is already installed. You can test whether Java is installed by opening a command window and typing
    		c:\>  java -version
  3. Download and install Xeena from IBM Alphaworks http://www.alphaWorks.ibm.com/tech/xeena (~5MB).

    Make sure that you retrieve version 1.2EA, not version 1.1. Xeena is used to build to the X3D-Edit tool.

    • You need to acknowledge the nonrestrictive licenses.
    • It is best to stick with the default installation C:\IBM\Xeena subdirectory.
    • When Xeena asks for which version of Java to use, select Java 2 (Runtime Environment or SDK).
    • Then point the installer to the destination directory where you installed Java (typically C:\jdk1.3.1, not C:\jdk1.3.1\bin). You might also find the JRE installed in a directory like C:\Program Files\JavaSoft\JRE\1.3.1_09
    • No "proxy host" entry is needed, this is for use behind restrictive firewalls.
    • Default values on other entries work fine.
    • Go ahead and view the example "addressbook" example. If you get an "Out of environment space" error, see the bugfix below.
    • Once installed, Xeena details can be found on the Help (user guide) page, installation README page, and Frequently Asked Questions (FAQ) pages.
    • Once installed, test installation by running the Xeena AddressBook DTD Example.
  4. If you need an unzip program, get PKZIP (from http://www.pkware.com).

    Make sure your unzip program's preferences install the zip into your top-level directory on C:\ and preserve all subdirectory folder names (the X3D-Edit code unravels/merges everything into C:\www.web3d.org\x3d\content\* )

    You can also unzip a zipfile using Java as follows. Be sure to run this from your topmost (root) subdirectory.
       C:\> jar -xvf X3D-Edit.zip
  5. For GeoVRML extension support, you may need to also install GeoVRML.
  6. For DIS-Java-VRML extension support, you may need to also install DIS-Java-VRML.
  7. Download Updates

  8. Download the X3D-Edit distribution (~12 MB) from

  9. Recommended installation: download the X3dExamples distributions

    Unzip from your top-level directory as follows:
    C:\> jar -xvf X3D-Examples.zip

    Again, make sure your unzip preferences preserve the subdirectory folder names and install the zip into your top-level directory on C:\ (it unravels into C:\www.web3d.org\x3d\content\* )

    The X3D Examples are also viewable online at
    http://www.web3d.org/x3d/content/examples and

  10. Recommended installation: download the ConformanceNist Examples distribution (~150 MB) from

    The ConformanceNist Examples are also viewable online at http://www.web3d.org/x3d/content/examples/ConformanceNist.

    Unzip from your top-level directory as follows:
    C:\> jar -xvf ConformanceNistExamples.zip
  11. All done!

X3D-Edit files are open-source public-domain products from the X3D Task Group.
The nonrestrictive Sun license for Java and the nonrestrictive IBM license for Xeena are provided when downloading/installing each of those tools.
IBM has generously agreed to allow the Web3D Consortium include Xeena on the Web3D/X3D Software Development Kit (SDK).


  1. Launch icons for X3D-Edit are placed on the Windows 95, 98, NT and 2000 desktops.

    A copy of the X3D-Edit launch icon is also available in the C:\www.web3d.org\x3d\content subdirectory.

  2. Windows shell invocation:

        D:> C:
        C:> cd \www.web3d.org\x3d\content
        C:\www.web3d.org\x3d\content> X3D-Edit.bat
  3. Unix shell invocation:

        % source x3d-edit.sh
  4. Xeena details. Good things still worth checking out: local copy of the installation README helps troubleshoot installation problems. You can learn all about the user interface by reading the Help (user guide). Anything else might be found on the Frequently Asked Questions (FAQ) page.

Compact Form

This section no longer pertains to the current version of X3D. You can safely ignore it, documentation of the compact and compromise forms is retained for archival purposes only.

You can easily simplify legacy content to remove "wrapper tags" (<children> <appearance> <geometry> etc.) by using X3dUnwrap. This also lets you upgrade to X3D-Edit version 1.7 from earlier versions.

Select Tools then Process XSL from the top menu. Use the X3dUnwrap.xsl stylesheet as shown to unwrap your scene. Backing up your original file (or saving to a different filename) is a good idea. The Process XSL window can be stretched left-right for easier reading.

The stylesheet also updates the tagset document type definition (DTD) from x3d-compromise.dtd to x3d-compact.dtd.

Example screen snapshots show "before" (compromise wrapper tags, X3D-Edit version 1.6) and "after" (compact unwrapped, X3D-Edit version 1.7) scene graphs.


Some miniscule detail about this project follows. This is primarily for documentation purposes and is not needed for regular use.

Alternate Usage for Developers

Besides X3D-Edit.bat, example Xeena editor invocations under Windows follow. Edit to match your your locally installed subdirectories as needed.

C:\ibm\Xeena> xeena.bat  -dtd c:\www.web3d.org\x3d\content\x3d-compromise.dtd  -root X3D

C:\ibm\Xeena> xeena.bat  -dtd c:\www.web3d.org\x3d\content\x3d-compromise.dtd  -root X3D  -xml c:\www.web3d.org\x3d\content\examples\AllVrml97Nodes.xml

There are many example invocations and shortcuts in the Makefile.

Alternate Installation Directory

Not recommended (which means "skip this section"). If you insist on changing the installation directory (!) then you will need to edit the second line (DOCTYPE) of x3d-compromise.dtd, and you will also need to edit the following files: x3d-compromise.profile.X3D-Edit-1.6, x3d-compromise.profile, X3D-Edit-1.6.bat, X3D-Edit.bat and Makefile (if used) to match your local directory structure. You will likely have to edit the examples as well, though if you are connected to the network, Xeena will try to find the website version of the DTD.

XSL Stylesheets and Translation Utilities


Many bugs are avoided altogether (especially Windows ME and 98) by using the X3D-Edit Auto Installer for various operating systems (Windows, Mac, Linux, Unix/Solaris).

0. X3D-Edit can't open example scenes due to being disconnected from the network. The underlying Xeena tool can't be modified to substitute local DTDs for online DTDs, causing a validation error when opening most scenes when offline. The best correction to this problem is simply to connect to the network.

1. Xeena/X3D-Edit works under JDK 1.4, except for the "Allowed Nodes" pane. Workarounds: use the other panes, install the X3D-Edit Auto Installer version, or supplement JDK 1.4 with JDK 1.3.1_09 instead.

2. A common installation problem follows. This can occur under Windows 95, Windows 98 or Windows Millenium (ME). The fix is the same either way.

] If you're running Windows 95/98/ME, and encounter an "Out of environment space" 
] error, then you'll need to increase the size of the environment table.  
] You can do this at the command line (which is temporary) or by editing 
] a configuration file to make a permanent change (which requires restarting 
] your computer). 
]      To temporarily increase environment space for X3D-Edit.bat, 
]      first enter the following command at the DOS prompt: 
]         C:\www.web3d.org\x3d\content>   command /e:8192 
]         C:\www.web3d.org\x3d\content>   X3D-Edit 
]      To permanently increase environment space, 
]      add the following line to your C:\CONFIG.SYS file,
]      save all files, and then restart (reboot) your system: 
]          shell=command.com /e:8192 /p 
]      Once you've increased the size of the environment table,
]      try running Xeena again.  If there is still a problem,
]      please cut/paste the command-window text into an email and
]      report the problem.

Alternative for Windows Millenium (ME) from Tom Greenwald, NPS.

] For both Xeena and X3D-Edit I had to right click on the icon, left click
] on properties, click the memory tab, set the initial environment to
] 4096, set extended (XMS) memory to 8192, and set MS-DOS protected mode
] (DPMI) memory to 8192.

You may need to reboot your computer for these changes to take effect. You will also have to repeat this step whenever you update X3D-Edit, so you may prefer the permanent change above.

3. If you use the older version 1.1 of Xeena (instead of 1.2EA), the following errors appear:

	  -dtd "c:\www.web3d.org\x3d\content\x3d-compromise.dtd"
	  -root X3D 
	  -xml "c:\www.web3d.org\x3d\content\examples\newScene.xml"
	Syntax error
	Syntax error
	running Xeena with Java 2
	Exception in thread "main" java.lang.NoClassDefFoundError:

To fix this problem: uninstall Xeeena 1.1, install Xeena 1.2 EA, and again extract X3D-Edit.zip (to correct the Xeena CLASSPATH bug). Or simply uninstall X3D-Edit and use the autoinstaller instead.

4. After importing a VRML97 scene, the XSL buttons do not work.

The following obscure message may appear in the console:

 java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Fix: save the imported scene as a file. This may require renaming your scene if it was originally a read-only file (such as newScene.x3d). The XSL buttons now work. See above for more instructions on using the VRML97 Import capability.

5. Insufficient memory.

You will need 128MB of RAM or more. Yes, 128.

6. The window goes blank and locks up before displaying a scene.

This is likely a DOCTYPE/DTD problem: Xeena is attempting to retrieve the DOCTYPE/DTD via the network, without success. When using Java 1.3 or earlier, this problem can only be fixed by replacing the DOCTYPE/DTD or else by connecting to the network, thus gaining access to the final DTD url.

Fixes and workarounds:

7. You want to use an http proxy server.

The http proxy server feature is for loading a file via the Web. Not a very common setting, but nice to have nevertheless.

You will need to uncomment and update the line in X3D-Edit's modified C:\IBM\Xeena\Xeena.bat for set PROXY_SETTINGS. Warning: we've had trouble with this feature under Windows 98.

8. Some developers might not have Make installed...

Make is not necessary to run X3D-Edit, it is only used for X3D-Edit source development. The Makefile is being replaced by an Ant build file.

Make is available via the Cygnus distribution of GNU Utilities for PCs at http://sourceware.cygnus.com/cygwin. The Cygwin distribution provides Unix command line and utilities on Windows 95/98/NT/2000. Don't forget to upgrade your PATH with something like C:\cygnus\cygwin-b20\H-i586-cygwin32\bin;. Once Make is installed, edit the Makefile filename/directory definitions to match your local installation. There are a bunch of alternate example invocations in the Makefile if you know how to grok Make.

9. X3D-Edit can't seem to find the correct version of Java.

Set the JAVA_HOME environment variable to the installation directory for Java on your system and X3D-Edit will use Java accordingly.

10. No X3D scene appears in the browser.

Install a VRML or X3D plugin in your Web browser.

11. Internet Explorer (IE) blocks viewing the 3D scene.

The following screen snapshots illustrate this problem and 2 solutions.

When the plugin is blocked from showing content, the following warning bar appears near the top of the browser. Right click and select "Allow blocked content..." then select "Yes" to confirm.

Windows Xp Allow Blocked Content To Run For One Session

Correct integration of the plugin then appears:

Windows Xp Allow Blocked Content To Run Result

You can permanently reset this permission by selecting Internet Explorer -> Tools -> Internet Options... -> Advanced and then under Security select "Allow active content to run in files on My Computer" as follows:

Windows Xp Allow Blocked Content To Run Internet Options

Similar selections can be made for automatically running content from a CD, over the Internet, etc.

12. How do I quickly update X3D-Edit and examples?

Menu shortcuts are provided under windows to easily retrieve updates. Always extract all .zip files to the C:\ root directory.

Windows Start Program Menus X3d Updates

13. IBM Haifa was very attentive in responding to bug reports regarding Xeena, the interface tool. Unfortunately, despite the popularity of Xeena, their team is no longer working on this tool. We hope to fix known Xeena bugs someday. Nevertheless it still usually works fine for X3D-Edit.
