Before starting, you are strongly advised to read the VTK file formats documentation here.
Introduction
The purpose of this wiki is to show how one can write VTK files using python.
Why using python ? Because it's beautiful & powerful, of course ! ;-)
Obviously, you can use your favourite programming language to write such files. Mine is python. No more, no less.
In the following, the data you want to write to a VTK file are supposed to arise from scipy/numpy arrays. Please browse scipy.org to get more information if needed.
Before writing VTK files, you have to know that there are two kinds of VTK files: "legacy" VTK files and "XML" VTK files. The first kind is quite obsolete now, but still widely used. Although it is easier to write than the XML kind (understand: with low-level instructions like "printf" in C or "print" in python), this wiki will focus on the last kind, the XML format.
