3. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group DotNet, CLR, MSIL, C# … blabla

4. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group Java (J2EE) vs..NET: Performance

5. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group Java (J2EE) vs..NET: Portability - Java - Multi platform (available for every OS) - „Not really“ multi language -.NET - „Not really“ multi platform (  ROTOR, MONO) - Multi Language (C++, C#, J#, Basic, Delphi …)

6. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group Java (J2EE) vs..NET: Future - Java - well established - a lot of applications already exist (including Applets) -.NET - Microsoft's choice for Windows Longhorn - a lot of applications are ported to.NET

7. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group Native Code vs..NET: Performance - Native Code, the compiler - usually compiles everything only once - has much time to optimize code - has no idea of the target machine - can’t do runtime optimization on it’s own -.NET, the JIT … - compiles every USED method ONCE per program execution - needs to be fast - knows the target machine well - knows the program’s behavior See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/dotnetperftechs.asp http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/dotnetperftechs.asp

8. computer graphics & visualization Jens Krüger & Polina Kondratieva – Computer Graphics and Visualization Group Let‘s get started … - you need: - Windows XP/2003 (Windows ME/98/2000 no supported) -.NET Framework 1.1 (SDK not needed) - Visual Studio.NET 2003 - DirectX 9.0c SKD (April 2005 Update) - Cool is: - a GPU capable of DX9 -ATI Radeon 9xxx / Xxxx / FireGL and above -All NVIDIA GeForce FX / Quadro FX and above - a GPU capable of SM3 -All NVIDIA GeForce 6xxx / Quadro 4400 and above -Next generation of ATI cards Use the systems in our lab!!!
