The MayaVi home page is at: http://mayavi.sourceforge.net. Please visit there for the latest information on MayaVi. This document describes the installation procedures for MayaVi.
There are currently three ways of installing MayaVi.
The stand-alone binaries are available for Win32 and Linux. They allow you to install MayaVi as an application without having to install VTK or even Python! If you are going to use MayaVi as a Python module then it is recommended that you install it from the sources.Currently there are two binaries available. One for Win32 and the other for Linux. The Linux and Win32 binaries were made using Gordon McMillan's Installer. The Windows installer was made using InnoSetup. Installing the binaries is pretty straight forward. The download is pretty big since it comes bundled with everything necessary to run MayaVi.
Both the binary installations ship with a doc/ directory containing a quick installation guide, README, etc. and a user guide in doc/guide/book1.html. Also included is an examples/ directory that contains a sample VTK data file of a heart CT scan and a visualization based on that data.
Just download the binary, run it to start the installation, answer the questions on where you want to install it etc. That's it!
Installing the Linux binary is also fairly straightforward. The Linux binary is simply a bzipped tarball. Untar it and run the mayavi program in the untarred directory. The binary requires the following:
Installing the RPM requires that you have installed Python, Tkinter and the VTK RPMs for VTK and VTK-Python. If you are using Python2.2 make sure you download the RPM for Python-2.2. Once you have these working you can simply install the appropriate (depending on your Python version) MayaVi RPM. If you have installed VTK from the sources and not via RPMS there should be no problem with installing the MayaVi RPM.
To install the Debian package simply install the current Debian MayaVi package (using apt-get install mayavi). This will rope in all necessary dependencies. Then simply install the downloaded Debian package. Debian ships with VTK 3.2. More recent VTK 4.x binaries (not debs) that work under testing (for the i386) are available here. These binaries are built under woody/testing.
MayaVi uses distutils for the installation process.
If the requirements are all met, installing MayaVi is simple. Download the tarball, untar/unzip it, change directory to the new directory and do the following:
% python setup.py install
Thats all there is to it. Under Linux you might want to run this
command as root. For more help on the various options for the
install command try this:
% python setup.py install --help
For more help on distutils look here.
Please note that if you simply want to run MayaVi without installing it as a module you can always run it straight from the untarred directory like so:
% mayavi [options]
Once you have MayaVi installed and running, you can test it by using the example files in the examples/ directory of the sources. The directory contains a sample VTK data file of a heart CT scan and a visualization based on that data. To run this visualization use the File->Load->Visualization menu and choose the example in the examples directory of the MayaVi source tree. If this loads fine then you are all set! For more information on how to use MayaVi read the MayaVi users guide. This guide is also included along with the source and is in the doc/guide/ directory.
Usually the hardest part of a MayaVi install when using the sources is getting the VTK Python bindings installed properly. The next section tries to address this.
Before you can run MayaVi you need to have VTK installed and working properly. There are two ways to install VTK on any platform. One way is to build the packages from the sources and the other is to download pre-built binary packages. VTK is a huge package and building from source is not for the weak hearted. You can download binaries and sources from the VTK download page.
Instructions on how to build VTK suitably under Windows for MayaVi are available here. You should also read the README.html that is included with the VTK sources. When building VTK from the sources make sure that you build the Python bindings. It is a good idea to build the Tcl bindings also since that ensures that the VTK-Python Tk widgets are also compiled.
Pre-built VTK packages are available for Linux and Win32 and these are mentioned below. If installing VTK from sources is a hassle you should consider trying these instead.
The Linux and Win32 binaries pages should be updated reasonably often so do check them out.
Included along with the MayaVi source is a file called test_vtk.py in the doc directory. Run this to test your VTK installation like so:
% python test_vtk.py
If this runs without problems then your VTK installation is ok. You should then install MayaVi from the source and try to run it. If you have trouble the script will tell you where it failed. At this point if you are unable to proceed email us.
