I’m a newbie at Joints. Goal is to create plane, and wrap plane around cube like wrapping a gift.

I understand and am able to set up a plane, create joints and fold plane to form 1st part of cube.

What I do not understand is how to add additional joints perpendicular to start folding, tucking the left and right sides to enclose the sides of remaining open ends of the cube, which involves triangular folds.

I have set up the joints, but don’t know how to get secondary, side joints to be part of main joints.

Thank you for your help Cineversity!

Hi TCG,

I haven’t done it for a complete gift wrap animation, but you need to think all steps in advance. In other words, just to get to a point with one complete set of joints. To add new ones later will not work. All joints need to be there from the start.
This is done in a hierarchy, like a tree, with some joints equal in position in the hierarchy, so the parent of several joints will move the child objects, and then the child objects move perhaps the next lower level in the hierarchy of joints.
All joints, in any way and at any time must meet the 100% influence to a single point as a summery. This needs to be there, again, from the start. Think of a hand in a glove [mittens], the wrist moves all but the fingers can move the enclosure of four fingers. Fold a paper in the way you want, and then think about the points of your mesh, step by step, which one needs to be moved. The joints and their target point should sit on these points. (Well, I do not know what mesh you have…)

Another way would be the Pose Morph and Rotational with the axis set for each step.

If you have a sketch or something more “visible”, let me know.

All the best

P.S.: here is a sketch. I’m not certain if the V constellation for the sides was a good idea. Perhaps a T formation would be nicer, but one more joint on each side, and easier to animate. If a complete wrap is wanted, the T option instead of the V will make even more sense. Again, this is a sketch, as you can see that the “blue” joints overlap timewise, not a biggy and not important in terms of the set up. Sketch.

Thank you Dr. Sassi! Thank you for the R&D sample!

Hi TCG,

You are very welcome. This was only a little sketch.

Please let me know if there is another question.

All the best
