QSMP3 is a MP3 Playback component for Delphi and Kylix. It allows you to add full MP3 playback capabilities to your application under both Win32 and Linux. It is a non-visual component, so it should be functional under Linux CLI, X11, Win32 GUI, and Win32 (not DOS) CLI. Supported capabilities include playback, stop, pause, seek-by-time-index,seek-by-byte-indes, automatic position reporting (by event), and position reporting by function call. This component relies on SDL, SMPEG, and the JEDI-SDL translation of the SDL and SMPEG headers to Pascal.
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.
ddrescueview is a small tool that allows the user to graphically examine ddrescue's log files in a user-friendly GUI application. The Main window displays a block grid with each block's color representing the block types it contains. Many people know this type of view from defragmentation programs. The program is written in Object Pascal using the Lazarus IDE. It can be compiled to run on Windows, GNU/Linux, and probably OS X too. The downloads include binaries for the respective target platform and the project files (source code).
The Castle is a first-person shooter game in a dark fantasy setting. Your main weapon is a sword, so the fight is mostly short-range. Three main levels are included, packed with creatures, items, and sounds. A couple of bonus levels are also available, like the classic DOOM E1M1 level reimplemented in VRML. The game engine is based on VRML, OpenGL, OpenAL, and all shadows are done by the shadow volumes approach.
