2/// \ingroup tutorial_geom
3/// Creates and runs a simple iterator plugin connected to TGeoPainter iterator.
4///
5/// It demonstrates the possibility to dynamically change the color of drawn
6/// volumes according some arbitrary criteria *WITHOUT* changing the color of the
7/// same volume drawn on branches that do not match the criteria.
8///
9/// ~~~{.cpp}
10/// To run:
11/// root[0] .L iterplugin.cxx+
12/// root[1] .x runplugin.C
13/// root[2] select(2,kMagenta);
14/// root[3] select(3,kBlue)
15/// ...
