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.
VMD (Visual Molecular Dynamics) is designed for the visualization and analysis of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD provides a wide variety of methods for rendering and coloring a molecule: simple points and lines, CPK spheres and cylinders, licorice bonds, backbone tubes and ribbons, cartoon drawings, and others. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer. VMD uses OpenGL and OpenGL Programmable Shading Language for high performance rendering of large structures.
The Visualization ToolKit (VTK) is an object oriented software system for 3D computer graphics, image processing, and visualization. VTK includes a textbook, a C++ class library, and several interpreted interface layers including Tcl/Tk, Java, and Python. VTK supports a wide variety of visualization algorithms including scalar, vector, tensor, texture, and volumetric methods. It also supports advanced modeling techniques like implicit modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation. Moreover, dozens of imaging algorithms have been integrated into the system. This allows mixing 2D imaging / 3D graphics algorithms and data.
MayaVi is a free, cross platform, easy-to-use scientific data visualizer. It provides a powerful GUI to ease the visualization process. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. MayaVi can be scripted from other Python programs and also from the interactive Python interpreter. MayaVi includes the VTK Pipeline browser. The VTK Pipeline browser is a Python module (vtkPipeline) that enables one to view and configure the objects in the VTK pipeline graphically with a Tkinter-based GUI. The browser should work for any Python script that uses VTK. MayaVi also provides classes to pickle a VTK object and a simple class documentation browser.
Wallpaper Control is a non-window manager-specific wallpaper manager for the X Window System. It aims to be a full featured utility for managing and setting your images you use as wallpaper. Features include a preview window, directory listing, and deletion of graphics from hard drive.
wApua is a WAP WML browser written in Perl with a Tk user interface. It uses libwww-perl as its backend, has history and cache, and can display most WML tags, including tables and WBMP images. It includes a WBMP to XBM (wbmp2xbm) converter for command line use. It runs under X11 on Linux, BSD, Solaris, and Mac OS X as well as on Windows (both native and under Cygwin with X11). It should also work on other operating systems which are supported by Perl 5.6 or higher and Tk 800 or higher.
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.
