ISUther Posted January 2, 2019 Share Posted January 2, 2019 I need to create a rolling plans / paper animation clip. What approach would you recommend? Paper should roll to table like rolling architectural plans or some sort of map. What nodes you would use? I was thinking bend node but may be there is some other more effective method? Some sort simulation? Quote Link to comment Share on other sites More sharing options...
DaJuice Posted January 2, 2019 Share Posted January 2, 2019 Matt (@mestela) had a nice solution for this using the Bend SOP. I think you could accomplish that using two of them. https://www.sidefx.com/forum/topic/49396/ Quote Link to comment Share on other sites More sharing options...
ISUther Posted January 2, 2019 Author Share Posted January 2, 2019 yeah that what i was thinking also. Trying to use it will see how it turns out. Need later to make 2d drawing occur to the paper also. Like lines that come to one and create a house. Quote Link to comment Share on other sites More sharing options...
Atom Posted January 2, 2019 Share Posted January 2, 2019 (edited) Bend does work in this case. To reveal the 2d drawing, you might want to create an image sequence in a compositing app and feed it to the Houdini shader system as an animated texture map. ap_unroll_scroll_010219.hiplc Edited January 2, 2019 by Atom Quote Link to comment Share on other sites More sharing options...

How did you start it did you do the left pipeline before right one? 1. Grid 2. uvtexture 3. bend unroll left 4. bend unroll right can you explain the right bart. Curve Scroll Flat and Curve Scroll unfurled ? Quote Link to comment Share on other sites More sharing options...
Atom Posted January 2, 2019 Share Posted January 2, 2019 (edited) I just got one side to work then copied that bend node and placed it next in line. I flipped some of the axis so it was pointed in the negative direction. I think I animated the origin in each direction as well. Oh, that other junk was just left over from a first attempt. I wondered if it were possible to just animate a curve profile using a BlendShapes but there is some point ordering issues with that approach.

Do you know how to add extra turns to end and start or paper rolls? Getting weird issues when trying to add another bend. Here is video where i try to explain this. Hope it helps and you can assist. Or anyone in this matter. I am noob in Houdini day by day trying to learn more. Sirkel_Mall_Logo_Projekt.hiplc Quote Link to comment Share on other sites More sharing options...
Noobini Posted January 2, 2019 Share Posted January 2, 2019 well think of OTHER ways...there's no rules saying you have to do the same thing others have done before you. Vellum, 2 cyls, stick left/right edges to the cyls...roll cyls towards middle. If I just GIVE you the file...where's the satisfaction in exploring on your own ?
