Debug info on screen from cake application

I saw a video that show the cake application with info printed on screen and collision shapes. How can I render collision shapes?

mWorld->createDebugRenderer(...);

My Intellisense and Compiling log say that "CreateDebugRenderer is not a member of NxOgre::World .....

You need to activate it.

Goto "NxOgreStable.h" in the NxOgre project, find the compiler switch (it's a define), and recompile NxOgre.
