OpenVRML is a VRML and X3D browser plug-in and C++ toolkit for incorporating VRML/X3D support into applications. It provides VRML97 and Classic VRML X3D parsers, a runtime, and an OpenGL renderer as C++ libraries. The renderer is fully separate from the runtime library so that users can also provide their own renderer. The OpenVRML browser is provided as a D-Bus service, and is embeddable in host applications using XEmbed. The distribution provides both a stand-alone host and a host that runs as a Mozilla plug-in.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for ASCII rather than binary transfer), it has since been extended to check and optionally print almost all the information about a PNG image and to verify that it conforms to the PNG specification. It also includes partial support for MNG animations.
Web Photo Album automatically generates photo albums on the fly from directories containing your favorite photos. Supports captions (including HTML tags), definable page sizes, forward and reverse preview, and index pages. All preview and index pages can be clicked to jump straight to the page that contains them. Album maintenance is easy -- just add or remove photos and (optionally) captions to your album directory.
The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. There are currently six components: 1. Web Static Analyzer Tool (WebSAT): checks web page HTML against typical usability guidelines. 2. Web Category Analysis Tool (WebCAT): lets the usability engineer construct and conduct a web category analysis (card-sorting). 3. Web Variable Instrumenter Program (WebVIP): instruments a website to capture a log of user interaction. 4. Framework for Logging Usability Data (FLUD): a file format and parser for representation of user interaction logs (such as those captured by WebVIP). 5. VisVIP Tool: produces a 3D visualization of user navigation paths through a website, based on FLUD data. 6. TreeDec: adds navigation aids to the pages of a website.
