i am trying to find a way to aproach, animating a curve along a mesh surface, like having a wire creating a mesh. I thought about having a curve snapped along the mesh and then animate the wires. Do you have any reference tutorial or any idea how to aproach it? Here is a reference image:enter image description here

and here is a second: enter image description here

Thank alot

  • I guess what you want is not clear and need a little bit more explanation – moonboots Aug 30 '18 at 16:12
  • Yeah i know, i dont have even have a reference video, i was asked from aclient that has a ed model of a head. if there is a way somehow to be created from wires. – Phaidonas Gialis Aug 30 '18 at 16:15
  • you mean a wire moves until it creates the shape of a head? With Empty Hook you can control the vertices of a curve – moonboots Aug 30 '18 at 16:19
  • i mean having a wire going along the periphepy (maybe spiral move) of an object, untill it completes the shape. Here is an image that resembles it https://www.google.gr/search?rlz=1C1MSIM_enGR760GR760&biw=1920&bih=943&tbm=isch&sa=1&ei=WhqIW5qAAcedsAfZ05vIAQ&q=spiral+head+esher&oq=spiral+head+esher&gs_l=img.3...9006.11434.0.11948.9.9.0.0.0.0.128.1099.0j9.9.0....0...1c.1.64.img..0.1.122...0j0i30k1j0i10i30k1j0i8i30k1.0.wIvBJ6IXPSo#imgrc=aw971AknW-lDFM: – Phaidonas Gialis Aug 30 '18 at 16:26
  • oh ok interesting – moonboots Aug 30 '18 at 16:30
  • perhaps create a mesh for the head, then a bandage that will stick to the head with a shrinkwrap, then put some hooks or bones to control the bandage, and use the Projection Painting technique to paint the bandage? https://www.youtube.com/watch?v=eQy5jn9dWrs https://www.youtube.com/watch?v=uxD0qaTFZnk https://www.youtube.com/watch?v=sZDMFkj8GqA – moonboots Aug 30 '18 at 16:36
  • it is not the exact image, i am still trying to find a better reference – Phaidonas Gialis Aug 30 '18 at 16:42
  • I changed the reference we a much more acurate,This image was created with c4d – Phaidonas Gialis Aug 30 '18 at 16:46
  • is it supposed to move and if so, how? – moonboots Aug 30 '18 at 16:48
  • I think trying to fill the shape, having like an infinte cable tha goes all along the surface until it fill the shape. – Phaidonas Gialis Aug 30 '18 at 16:51

    Do you need to move the noodles or are they just lengthening along still curves? You can create some cylinders, then with Array + Curve modifiers, you increase the Count of the Array and the noodles will lengthen along the curves. If you put some Hooks along the curves you can also move the noodles if needed. Maybe those hooks could stick to invisible spherical shapes... – moonboots Aug 30 '18 at 17:36
  • i thought about faking it, i dont think that i will do it for the client, it does not have good value for money, but i thought about creating a script. In pseudocode, it is like trying to connect all dots without overlapping. – Phaidonas Gialis Aug 30 '18 at 17:40

    So why not create spiral curves, then you duplicate a cylinders along them with an array modifier – moonboots Aug 30 '18 at 17:47
  • Because it will not have the detail, of working with a head model or other more complex shapes. – Phaidonas Gialis Aug 30 '18 at 17:55
  • You could create your shape, then create and extrude a curve along this shape with Snap enabled (type of element to snap to: face) so that it sticks to it. Then the animation will be the cylinder increasing its array count and following the curve. – moonboots Aug 30 '18 at 17:59
  • This was my initial thought,I start doing it and it was like a helling boring work, doing all the head and my second thought was animation nodes, but I couldn't find any reference – Phaidonas Gialis Aug 30 '18 at 18:04
  • yes a bit boring, but pretty easy to do, but maybe someone will have a better idea ;) – moonboots Aug 30 '18 at 18:06

    Somewhat related .. this tutorial using Animation Nodes – Robin Betts Aug 30 '18 at 18:09
  • yessss, just before going for sleep, i think it is a very good start. – Phaidonas Gialis Aug 30 '18 at 18:15
  • If you succeed in putting some order into that approach, I would love to see your answer to your own question. :) – Robin Betts Aug 30 '18 at 18:22
  • You need to clarify how should the wire animation look like, it's unclear. How to make the wire is here: https://blender.stackexchange.com/questions/94991/trace-visualisation-in-3d-how-to-wrap-curves-onto-a-3d-mesh. – Jaroslav Jerryno Novotny Aug 31 '18 at 06:01
  • I don't have much experience with it, myself, but it sounds like you should look into the Build modifier. – Lee Oct 15 '18 at 19:50

This tutorial deals with the animation of stuff along curves. Your model might be complicated to set up this up for, though.

  1. Create a sphere.
  2. Create couple of curves with depth
  3. Use shrinkwrap modifier on each curve. In shrinkwrap modifier turn on "apply on spline" on the top bar.
  4. You can animate wires with bevel start/end option in curve panel.
