Not an easy one, but I finally managed to attach some geometry to the rig from the first part of this tutorial series. I used XPresso to attach a polygon object to the joints and to generate a fourth point, so that I’m able to map a popup book element onto this four-side polygon using the Surface deformer.
Here’s the equation to calculate the vector length and orientation C between two coordinates A and B (flip A and B for the other direction):
C = B – A
Thank you so much for sharing this with us Robert!
What a brilliant are u!
Keep it going..
Thanks a lot!
Thanks for the tutorial Robert — lots of lateral thinking in this one :)
I had a quick go at achieving the same effect using connectors. You can see the results here if you’re interested.

cheers!
looks like something i never could have come up with ;)
Haven’t tried this approach yet, but it looks pretty nice and simple!
Also thanks for the tips, for controlling the dynamics not to get too excited :)
I’ll definitely try it out to see how dynamics can handle it…Thanks
I LOVE the version with connectors! Nicely done!

Good idea!
I rendered your file but had the problem that the »left page« and »right page« broke apart during folding. I’m not a big expert in »C4D connectors« but do you think there are some settings to connect the elements more precise?

thanks oh great master f the c4d universe!!!….( I DID IT WELL??)
that’s okay for starters ;)
That’s what’s up!!!
“oouch – that hurts” – shut up, brain :)
Thx Rob!
Excellent job! Robert, I love all your tutorials–keep it coming–cheers!…:)
Again, very creative and clever use of Xpresso and Maths !
You really rocks and i must say, every tutorial you launch here is extremely useful and becomes immediately a “must watch” !
Congratulations for all your crazy work,
Thanks again and keep up the good stuff !
Wow,I’m speechless ! Thanks a lot for that credit, really appreciated and really glad I helped…although I should thank you for another Great tutorial and for all these great techniques you share with us…I mean, vector maths !? that’s ridiculous…who would have thought that? :p Not to mention the surface deformer…Awesome!
This tutorial is exceptional!
I wondered if you had the same problem as I’m having on output. When I pause mid page turn and preview render frame in the window the positioning of the rig adjusts and shows a perfect image. But when I do the final output the rig seems to ‘lag behind’ the page turn so I get intersecting pop up elements with the page? I can’t understand why this is happening?
Just found out, it’s something to with priorities.
In the expresso tag play around with the priorities settings and this should sort it.
Big :)
Hey John,
I have the same problem, been bugging me all day long.
Could you explain what you have done, and why?
thx!
Hey Robert,
Just having a go at Part 2 – I’m not sure what I’m doing wrong, but the rig still seems to be jumpy with the new method – I’m suspecting it has something to do with the middle constraint. As I animate the book element, it seems to be jumping to try and keep up with the middle null.
Sample: http://robmac.net/gifs/popupfail.gif
Advice would be appreciated!
I think I may have made a dumb mistake. When I changed my Pole Vector object from joint.Middle to null.Middle, it works fine. Sorry to waste precious comment space!!
Wow the connectors version works amazing!
