In the DLMF, we provide facilities for the interactive display of special functions of two independent variables. To do this we use VRML (Virtual Reality Modeling Language) and X3D (Extensible 3D). VRML is a standard file format for describing the behavior and geometry of a 3D virtual scene on the web. X3D, the successor to VRML, uses an XML format to represent 3D scenes and objects. With a VRML or X3D browser/plugin installed inside your web browser, you will be able to render the scene and interactively rotate, scale and otherwise explore the 3D surface. The VRML Plugin and Browser Detector lists VRML and X3D browsers available for your machine and detects any browser already installed. The installed browser should be removed before installing a new one.
Some VRML/X3D browsers are not capable of handling the complex files necessary for our visualizations. Below we provide some notes to supplement the download instructions for several browsers we have successfully tested for compatibility with our files (but see our Disclaimer). We have strived to provide the most current information available, but if any details appear to be out of date or confusing, or if you know of other VRML/X3D browsers that are able to display our files with full functionality, please notify us.
BS Contact is a product of Bitmanagement Software GmbH. It can be used to view either VRML files or files in the XML based format, X3D. To download the current version, go to Bitmanagement’s Download Center. Entering your name and email address will allow you to download an evaluation version with full functional capabilities. The company logo that moves randomly around the screen can be removed by paying a license fee.
Octaga Player is a VRML/X3D browser that can be downloaded from Octaga Visual Solutions. Selecting the download link provides you with a free non-commercial copy that appears to be sufficient to handle our files, but you may need to disable the collision option. Simply right click the screen, click Navigation, and click Collision.
We are currently assessing which other browsers for Linux platforms are sufficiently capable for viewing the DLMF’s VRML files. This page will be updated when more information is available.
