3. Ianna.Osborne@cern.ch Graphics The New Oxford Dictionary of English defines graphics as: the products of the graphic arts, especially commercial design or illustration; the use of diagrams in calculation and design; visual images produced by computer processing. the use of computers linked to display screens to generate and manipulate visual images. Graphics tools for GUI, 2D and 3D graphics

9. Ianna.Osborne@cern.ch IGUANA Interactive Graphics for User ANAlysis Main IGUANA focus - interactive detector and event visualisation: High- performance 2D/3D graphics; Graphical user interfaces; Data browsers. Integration of other tools, components The goal is to provide common look and feel for the CMS interactive graphical applications Interactive analysis is not considered a primary goal. It is assumed that this functionality will be provided by other tools (JAS, Hippodraw, Lizard, ROOT, or OpenScientist)

12. Ianna.Osborne@cern.ch Qt Toolkit Implicitly and Explicitly Shared Classes that use reference counting for fast copying. Input/Output and Networking Classes to provide file input and output along with directory and network handling. Multimedia Classes that provide support for graphics, sound, animation, etc. The Qt application framework's underlying object model. Organizers: splitters, tab bars, button groups, etc. Plugin Classes. Template Library: container classes. Text Related and XML Classes (DOM, SAX) Threading Classes Widget Classes Database related classes, e.g. for SQL databases. Date and Time Classes for handling date and time. Drag and Drop Classes dealing with drag and drop and mime type encoding and decoding. Environment Classes to create and handle events and to provide various global services (event handling, access to system settings,internationalization. Non-GUI Collection Classes such as list, queue, stack and string, along with other classes that can be used without needing QApplication. Graphics and Printing Classes to provide drawing (and printing) primitives, including OpenGL and digital image encoding, decoding and manipulation. Layout Management Classes to handle automatic resizing and moving of widgets, for composing complex dialogs.

14. Ianna.Osborne@cern.ch Qt Toolkit Platforms: Qt/Windows is designed for MS Windows 95/98/Me, NT4, 2000 and XP. Qt/X11 is designed for Linux, Solaris, HP-UX, IRIX, AIX, and many other Unix variants. Qt/Mac is designed for Apple Mac OS X.Windows A non-commercial version of Qt/X11 is the de facto standard C++ toolkit for GUI applications on Linux. The KDE desktop environment is based on Qt/X11. Used by CMS, LHCb, D0, etc. Recommended by LCG
