I have some objects - balls -, I need to make them organized according to a path or a bitmap.Is this possible without using manual object moves?


An example:

I'd like to organize/align my objects (balls) so that they occupy all dark pixels of this bitmap

  • $\begingroup$ No, I just need to make them statically aligned to a path or a bitmap. An example of what I need is to use a path, may be a text path, to align my objects to make them appear like text $\endgroup$ Jul 24, 2015 at 16:12
  • $\begingroup$ Can you show an example of the effect from somewhere else? $\endgroup$ Jul 24, 2015 at 21:30

This can be done with a particle system where density is influenced by the image as a texture :

  • create a plane and UV-unwrap it.
  • add a particle system to this plane :

  • in the texture tab change the influence from time to Density :

enter image description here

  • the result :

  • you need to create a path in blender, or just import it from other software

  • the path should be converted into a mesh object

  • now add a particle system to this path

  • choose (Verts) under (emit from)

  • select the other object that you want it to be duplicated on the path (under render select object and then choose the object name in the Dupli object field)

  • put a check box on (Rotation) and choose (object Z) under initial orientation

  • play with other options like the size, number, life time, until you get the object repeated on all the vertex that is on the path, and with the right size
