Panda3D sample programs in C++?

after installed Panda3D SDK 1.8.1, there are some nice sample programs written in Python that I can run and read its code.
Though I know Python plays an important role in Panda3D architecture, I want to ask that are there these sample programs in C++ exist?

Yeah, they have been posted on the forums.

Do you indicate the posts by author dri?

That sounds familiar, yes.
