Frequently Asked Questions (FAQ)

  1. I created a virtual environment and would like to publish it on the web. In order to do so, I need a viewer that will allow people to access it. Can Demotride help me ?
    Demotride is the best tool to do that since it allows, through its extensions, to better control the display and interaction parameters. This ensure that your virtual environment will be viewed as intended. Also, the installation is a snap, given the small size of the installation package to download. At under a megabyte, even those with a dial-up internet connexion can download it in seconds.
  2. Does Demotride support the whole VRML standard ?
    Yes, to the exception of:
    • The MovieTexture Node
    • The hitTexCoord and hitNormal fields of the TouchSensor Node
    • Url fields beginning by http or ftp, except for HTML files referenced by the Anchor Node
    All those are currently recognized but disregarded.
  3. What media file formats are used by Demotride ?
    The media file formats currently supported are .png and .jpg files for images and .wav files for sounds.
  4. Are scripts supported ?
    Demotride partially supports VRMLScript (often refered to by the ECMAScript or Javascript names), thus allowing for the use of the Math, Date and String objects. However some functionalities are not currently supported. These are:
    • MF type fields and events
    • SFNode type fields and events
    • The new operator
    • The Browser object
    • The print function
    Note: every line of code in VRMLScript must end with a semicolon.
  5. Does Demotride support compressed VRML files ?
    Not for the moment. To check if a .wrl file is compressed, open it with Notepad. If the content is not humanly readable, it's because it is compressed, so it must be uncompressed to be used by Demotride.
  6. Demotride seems to interfere with another of VRML applications installed on my computer. What should I do ?
    You can simply uninstall Demotride by going in the menu Start/Settings/Control Panel and then Add/Remove Programs and choose Demotride in the list.
  7. I am not able to zoom by using the middle mouse button, what can I do ?
    Sometimes, the middle mouse button can be associated with another function. You can reset it to its original function by going in the menu Start/Settings/Control Panel/Mouse.
  8. Demotride automatically opens .wrl (and .x3dv) files. Are there other ways to launch the application ?
    Yes, it is possible to create a shortcut to the program file demotride.exe (located at C:\Program Files\NRC\Demotride 2.1) and put it on the desktop. You can then drag the main .wrl (or .x3dv) file of the scene and drop it on the shortcut to launch the program.
    One can also launch the application by command line. Please refer to the extensions for the command line syntax.
  9. Does Demotride work with Windows versions previous to XP ?
    Yes, Demotride also runs on Windows 98/ME/2000 computers. This, however, requires the prior installation of the Windows Installer 2.0, downloadable from the following links:
  10. Where does Demotride come from ?
    The Demotride viewer is a technology of the Institute for Information Technology of the National Research Council of Canada.
  11. How can I get a commercial license of Demotride ?
    Simply contact the officer in charge from the Business Development Office.
  12. Is it possible to run Demotride on other platforms than Windows ?
    Yes, Demotride can run on Macs by using a virtualization solution such as Parallels Desktop for Mac.
    Linux users can also get a commercial license of Demotride that runs on the Linux operating system. In order to get it, please refer to the previous question.
