I'd like to create a line animation like this one :

(Jupiter Ascending UI for info)

enter image description here

The question has been asked here and the person who created this animation replied, but with indications for Cinema 4d's Thinking Particles along with a file :

Can this be replicated in Blender ?

I tried with particles & forces but i cannot get near that. For example, one of the problems is that particles are going in all directions, intersecting paths of each others.

Demo curve gif

Try making an array of a plane along a curve. Deform the curve with a displace modifier driven by an object, then flatten the shape to a hidden plane.

curve objects

Modifiers

Make a material with a few brick textures, use a Mapping node to animate their offset. This can drive the bricks along the surface to make a fake particle effect.

    $\begingroup$ Thanks for your insight, i was looking into brick textures into brick textures, following your comment, but your node setup works great, many thanks ! I'll have to study it as the control along the geometry is completely new to me... $\endgroup$ – Clem Aug 26 '17 at 17:00

You'll probably want to use curves but they can be hard to make without using Animation Nodes or some other addon. I have used particles with motion blur.

I made a curve and fit an object array along it. I applied a wind>curve force filed to the curve, while I applied a force>surface force field to the array object.

  • $\begingroup$ Thanks, but my problem is to make the lines not cross each other as seen in the reference image. I've come across a partial solution by emitting from a few aligned vertices with a curve guide, but it's still hard to control when i add more curves in it... $\endgroup$ – Clem Aug 25 '17 at 14:00
  • $\begingroup$ Ok then I'm thinking that procedural brick texture over an array curved plane might be better? $\endgroup$ – 3pointedit Aug 25 '17 at 23:24
