Houdini Tutorial: Paper Folding with Vellum

Support us on: www.patreon.com/entagma
In this video Chris covers a simple way of simulating origami like patterns in Houdini and Vellum, just using edge groups and (depending on how you count them) three or six lines of vex.
We can very much recommend watching Junichiro Horikawa's previous explorations on the topic here:

    Amazing ! It’s been a very long time we didn’t see any tutorials from you guys

    Cleanest paperfolding tutorial up to date.

    Elegant process. Presented so well that it looks simple (and it's definitely not if just trying to figure it out). Thank you!

    I like the shader of the paper. Could you provide a tutorial how to make it?

    Thanks for your tutorial, Chris. I am new in Houdini, and VEX is definitively the most complex aspect to figure out. I see you use a demo GEO to show the point index in relation to the folding action. But when you write the VEX you describe points 2 and 3, but the mesh has way more points. So how does one identify the folding edges by just describing two points when the mesh has way more information? Thank you

    the VEX code operates on point INDEXES 2 and 3: the primpoints() function returns an array of points. Wrangles (not set to Detail) operate in parallel across the entire geometry (or specified by group), so it's operating on the 3rd and 4th point of EACH primitive (which has 4 points). It's not referring to just 2 points.

    Amazing stuff as always, just wanted you to know that Patreon is fraudulently charging and so I had to stop the membership. Hope you guys do a different platform.

    Did anyone else get a tiny crumpled lump of paper after frame 10? Went over it repeatedly, can't see where I slipped up.

    Hello, can you elaborate what's happening here, please? if(inedgegroup(1,'fold_out',pts[2],pts[3]))i@group_fold_in=1;

    if points 2 and 3 of each prim are in the previously created edge group, put them in a new prim group.

    Hi there.. Is there a way to use attribute to control volume vop.. I have a weight mask.. and i would like that the volumevop to affect the geometry only where the mask is white or black..not on both. ? Thank you.
