= Visualization Toolkit  =

* The Visualization Toolkit [http://www.vtk.org VTK is an open-source, freely available software system for 3D computer graphics, image processing and visualization. 
* VTK consists of a C++ class library and several interpreted interface layers including !Tcl/Tk, Java, and [http://www.vtk.org/Wiki/VTK/Examples/Python Python].
* [http://www.kitware.com Kitware], whose team created and continues to extend the toolkit, offers professional support and consulting services for VTK. 
* VTK supports a wide variety of visualization algorithms including: scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques such as: implicit modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation. 
* VTK has an extensive information visualization framework, has a suite of 3D interaction widgets, supports parallel processing, and integrates with various databases on GUI toolkits such as Qt and Tk. 
* VTK is cross-platform and runs on Linux, Windows, Mac and Unix platforms.

== Setup Environmental Variables for C++ ==
{{{#!bash
$ module load vtk
}}}

[[Example VTK-C++]]

== Use VTK with anaconda python ==
To use anaconda python
{{{#!bash
$ module load anaconda
}}}

But the current version of anaconda doesn't have ''vtk'' package in default.

To install vtk package in local, first you have to create local python clone.

{{{#!bash
[fuji@cypress2 VTK]$ conda create -n my_root --clone=/share/apps/anaconda/2.1.0
src_prefix: '/share/apps/anaconda/2.1.0'
dst_prefix: '/home/fuji/envs/my_root'
Packages: 140
Files: 0

#
# To activate this environment, use:
# $ source activate my_root
#
# To deactivate this environment, use:
# $ source deactivate
#
}}}

Then do

{{{#!bash
$ source activate my_root
}}}

Now you can install vtk package,
{{{#!bash
$ conda install vtk
}}}

=== From next time, to use anaconda python ===
{{{#!bash
$ module load anaconda
$ source activate my_root
}}}
