Advanced Samples

Can anyone share the "Advanced Samples" documentation? I'm trying to derive a class but I want to make it properly so it is stable. I want to start with creating my own Point so it can be a point on a line, using local coordinate system, point between 2 points, etc. and the data will be saved/retrieved (ocaf), and moreover, during a "Compute" operation, it will update itself properly depending if the underlying geometry changed, and also will be able to become a support itself for downstream geometry. I believe this needs to be a derived class, as I don't see a current class able to handle this parametric geometry "out of the box"
