Vis5D is a system for interactive visualization of large 5-D gridded data sets such as those made by numeric weather models. One can make isosurfaces, contour line slices, colored slices, volume renderings, etc of data in a 3-D grid then rotate and animate the image in real time. There's also a feature for wind/trajectory tracing, a way to make text anotations for publications, etc.
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.
Deciduous Evolution uses a 3D recursive algorithm for drawing binary trees using intersecting cylinders in 3D space. All adjustable aspects of this algorithm are parameterized, and these parameters are evolved using a genetic algorithm. Statistics describing various metrics of the tree are instantiated, and fitness is calculated based on a number of weighted functions of these statistics. The goal of this project is to manipulate these weights to most accurately reflect the laws of nature, and observe the resulting trees. Using only a simple set of parameters, a recursive binary tree's growth can strikingly resemble that found in nature.
Verse is a network protocol and client/server application architecture for multiuser realtime distributed 3D graphics applications. It uses a lightweight server to store world data, and then relies on clients to connect and use the data in various ways. Verse uses subdivision surfaces as its single geometric primitive, which both conserves bandwidth and allows very good scalability and visual quality on modern 3D hardware.
WilmaScope is a Java3D application that creates real-time 3D animations of dynamic graph (network) structures. It comes with a number of layout algorithm plugins, and supports the easy creation of plugins for new layout algorithms. 3D geometries for graph element glyphs and algorithms for graph generation and modification are loaded dynamically as plugins, providing an extremely flexible platform for all manner of graph visualisation applications. The system has been applied with considerable success to a number of graph visualisation problems.
Teddy is an OpenGL-based 3D graphics library written in C++. Its main features are simple scene graph and windowing system-enabling multiple cameras, camera windows, and scenes. It focuses on easy and flexible manipulation of models and model materials in the scene graph. It contains a number of primitive objects like sphere, box, and cone, and it can load LightWave object and scene files.
The Java 3D API enables the creation of three-dimensional graphics applications and Internet-based 3D applets. It provides high-level constructs for creating and manipulating 3D geometry and building the structures used in rendering that geometry. With this software, you can efficiently define and render very large virtual worlds. Blackdown's version of Java 3D uses the OpenGL low-level API to take advantage of 3D hardware acceleration.
