Popup Book Pt.2 – Attaching designs

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!

  2. 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.

    “oouch – that hurts” – shut up, brain :)

    Thx Rob!

  6. Excellent job! Robert, I love all your tutorials–keep it coming–cheers!…:)

  7. 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 !

  8. 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.

      Hey John,

      I have the same problem, been bugging me all day long.
      Could you explain what you have done, and why?

      thx!

  11. 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!

  12. 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!
