fsv, the 3D File System Visualizer, allows you to view a collection of directories and files as three-dimensional geometry. It represents all or part of a filesystem as a collection of blocks of varying sizes, each labeled with a filename, and arranged in a manner consistent with the original directory structure. fsv can visualize any arbitrarily large collection of files, limited only by memory and hardware constraints. Program features include an integrated 2D interface, intelligent camera handling, and extensive use of animation. fsv requires OpenGL.
IBM OpenDX, the successor to IBM Visualization Data Explorer, (known simply as DX) is a general-purpose software package for data visualization and analysis. It employs a data-flow driven client-server execution model and provides a graphical program editor that allows the user to create a visualization using a point and click interface. Applications can also be built on top of portions of the Data Explorer system, so that custom, turnkey applications can be easily developed using DX as the computational and rendering engine.
K-3D is a 3D modeling, animation, and rendering system for GNU/Linux & Win32. Features include creation and editing of geometry in multiple realtime OpenGL solid, shaded, and texture-mapped views; unlimited undos and redos; complete extensibility at runtime through third-party plugins; animated procedural geometric effects; all parameters animatable through a consistent control-spline based interface; rendering pipeline to Renderman Interface compliant rendering engines; optimization for use with the Aqsis rendering engine, which features solid modelling, true displacement, and user programmable shaders; and support for background and batch rendering.
