It implements the class Scene.

thank you for your answer, but what i want to kow is what does class Scene do, look forward for you answer.
by the way, when i read polyhedra_ig2.cpp, i found a class named Se3r used in the code, but i can not found which file defined this class, so i do not know what this class meaning too, would you please tell me that where can i found the file?

You need to find a convenient navigation tool.
If you have no experience in command line tools like vim I would suggest kdevelop.
Therein you have search boxes and other methods to navigate in the source code and see where something is defined (e.g. right click->go to definition).

Scene represents "simulation". Contains bodies, interactions, materials, force, engines... also have moveToNextStep method... see core/Scene.hpp for more details.

In Python, most of O.something calls are actually internally redirected to current Scene instance [1], note the OMEGA.getScene()->something

Concerning the searching, you can also use command line tools like grep:

cd /path/to/yade/directory
grep -R "class.*PolyhedraPhys"
grep -R "typedef.*stateVector"
grep -R "using.*Se3r"

.* means any number of any symbols in regular expression
most Yade objects are (in C++) defined with keywords class, typedef or using.

i have installed Kdevelop in my ubuntu, i import the whole trunk file in to Kdevelop through a button in the left part of the software desktop, i can only read one cpp file but can not navigate to the class defined in the other cpp files, would please tell me how can i acheieve the navigate function through this software?

Robert Caulk (rcaulk) said : #8

In Kdevelop, you need to Open/Import project (upper left under Project drop down) the entire set of folders (build, install, trunk.

After letting Kdevelop index the source files, you will find a tab on the left called "Classes". Here you can right click on any class and "jump to declaration".

Can you help with this problem?
