Introduction
Cassandra is a generic VTK data viewer written in Java which provides native multiplatform support. Cassandra is the result of internal R&D of Artenum company around scientific data visualisation and its know-how in VTK [1][2]. The use of Cassandra is dedicated to 3D visualisation in pre/post processing. Cassandra has already been used for many application in scientific computing and space environment analysis. Cassandra already provides several processing filters such as cutting functions, isolevels and data threshold. Therefore, those filters can be easily extended by external plug-ins. Plug-ins can be any kind of data processing such as import/export module or VTK pipeline definition. Cassandra is actually a VTK framework providing the common features on generic VTK objects and simplifies the creation of external plug-ins. The existing processing filters are external plug-ins automatically loaded at the runtime. The plug-in loading can be done any time, even after the application starts. This feature allows a wide flexibility in the definition of filters and provides a highly customisable generic VTK viewer.

II. Key features
1) Pipeline viewer and editor
Cassandra is composed of a graphical pipeline editor that simplifies the understanding and the manipulation of the data processing and visualisation. This graphical representation of the VTK
