Building Applications with VTK Library Using Tcl, C++ and Fortran Components

Rapport interne.This report describes a technique to build visualization applications using VTK library and components written in Tcl, C++ and Fortran. VTK is a software system for computer graphics, visualization and image processing. VTK library is written in C++ however it provides interfaces to languages like Tcl, Python and Java. Though it is possible to write a whole VTK application in scripting language like Tcl, sometimes it is desirable to implement some functionality in compiled language like C/C++ or Fortran, for instance to have access to features not available in scripting language or for efficiency reason. This report presents in through details how to access VTK objects from different languages and how to mix Tcl, C++ and Fortran components in one application
