I didn`t design PLSM2, so I guess I`m not the one to answer, but nevertheless I think you should specify your question because I have no idea what you want to know. What exactly do you mean by "designing idea"? The purpose of PLSM2? The high level design principles used?
If you clarified this point perhaps someone who is more involved than me is going to answer.

I never looked inside the code myself (at the moment I can't even get it to run - please see my own thread inside this forum :) ), but since it is a scene manager it has to implement the Ogre::SceneManager-interface somewhere. Find the class inside PLSM2 that is derived from it and see how each method is implemented. The next step would be to work your way down the class hierarchy of PLSM2 from there.

I also think that you can skip the implementation details of the Octree (it uses an Octree, doesn't it?) because I this will be pretty straight forward. Better look at Wikipedia or something like that if you need information about the operations that can be done on an Octree.

Hope I could help you and didn't talk too much rubbish. I'm actually learning myself.

Best regards,

PLSM is - as the name suggest - a scene manager which specializes in paging terrain (Paging Landscape Scene Manager == PLSM).
The title of the forum gives this away.
For more insight, you'd have to use it. And browse the topics in this forum. :wink:

Don`t look into the source too much - you don`t really need to understand how things work to use PLSM2 - at least you shouldn`t start with that. For the beginning, read in the wiki http://www.ogre3d.org/wiki/index.php/Creating_a_PLSM_Application (there are other sheets there, too, just search for plsm) and try things out!
