Create your object and make it child of the page… it will follow the page.
In this video the scale of the objects are driven by the Turn Page value.
To obtain this result you need to follow these steps:
First add a Null object and make it child of the interest page.
Reset the coordinate of that Null added.
Open the page using the control of the preset so you can see and manage the position of the Null on the page using its X and Z coordinates.
Add your own object under the Null and reset its coordinates, so adjust the Y coordinate to make the object settled on the page.
If you want to modify the position on the page use only the null coordinates.
At this point the object will follow the page turning but it will be always visible, so It needs to be scaled down when the page is not in the expose position. You could keyframe the scale of the null manually or you could use XPresso to drive the scale value by the turn value.
A new feature for the Realbook preset is coming.
Now it is possible to bend the page position in the spine.
After a long period of inactivity, I resumed putting hands on C4D, and the first concrete approach came about thanks to this fantastic tutorial (see below). The guys are really good, but unfortunately almost all video tutorials are for Houdini.
Now, in the project file of the PopUp Book Tutorial you find a pdf that contains the written solution using the mathematic notation.
If there is some request I can think to add better figures for better understanding.
Hope you enjoy.

The Best Book Rig for C4D
With this tutorial that I prefer to call exercise I hope to give you the opportunity to explore a topic often poorly treated:
The Matrix (not the movie)
The prerequisites are a minimum of knowledge of trigonometry, a little bit of geometry and XPresso. It is not for all, but trust me, it is a simple task.
Since I have received some requests on how to concatenate the Bend Deformer automatically I planned on doing this exercise by providing the project file, so you can see everything in detail without having to write anything. But it would be more interesting to redo from scratch all the things.
If you have seen the Popup Book tutorial for Cinema 4D by Robert Leger and want to know how to solve the problem in the mathematical way read below.
Here is the Robert’s tutorial:
This is my result obtained with my solution:
