[edit] Obtaining Data

The sample data can be downloaded from the DataTissue repository

• http://image.diku.dk/svn/DataTissue/trunk

This data set is quite large so we offer a reduced collection of data that is suitable for most of our demos. This smaller data set is located at

• http://image.diku.dk/svn/DataTissue/trunk/demos

Besides freely available volume data sets (CT-scans and more) can be downloaded from the web-pages:

• http://www.osc.edu/~jbryan/VolSuite/downloads.shtml
• http://openqvis.sourceforge.net/index.html

The data is easily installed by copying it into any folder that one likes. Afterwards one needs to create an environment variable named DATATISSUE. This environment variable should point to the location where the data was copied to.

[edit] Accessing Data in Code

In our demo applications we use an environment variable

  DATATISSUE

This should point to the folder location where the demo application is supposed to look for its data files. One would often get hold of this value in the code by writing:

std::string data_path = get_environment_variable("DATATISSUE");
