vidma is a utility for manipulating virtual disk images. It can show basic information about the image or resize it. Resizing is done by in-place modification of a file holding the image or by creating modified copy of such file. The only currently supported format is VDI (Virtual Disk Image), mostly used by VirtualBox.
view3dscene is a browser for VRML (1.0 and 2.0) and X3D, and a viewer for other 3D model formats (3DS, MD3, Wavefront OBJ, and Collada are handled). It supports viewing the scene in the "Examine" mode and walking in the virtual world with features such as collision detection and gravity. Rendering is done using OpenGL. Many advanced 3D graphic effects are available, like mirrors (flat and through cube environment mapping), shadows (shadow maps and shadow volumes), GLSL shaders and more. The program can also convert files from 3DS, MD3, Collada and other formats to X3D and pretty-print VRML and X3D files.
vile is a text editor which is extremely compatible with vi. It has extended capabilities in many areas, including multi-file editing and viewing, mouse support, infinite undo, additional operators, and rectangular operations. Vile has an optional Perl interface for UNIX and NT. It can also be built as "xvile", which is fully X-aware, or "winvile" for Win32, with scrollbars, menus, etc.
