I am trying to create a scribble drawing but make it spherical as if the pencil or pen lines are twisted within. I have tried to extrude planes and uv map a texture to those planes and unfortunately I lose dimension when planes are parallel to the camera view.

enter image description here

Any thoughts to approach this would be appreciated.

    $\begingroup$ You might try using a curve object $\endgroup$ – gandalf3♦ Aug 12 '15 at 20:31
  • $\begingroup$ I wrote a small plugin (not addon.. so this must be run from the text editor and it will add itself to the 3d view) -- gist.github.com/zeffii/9497c16760f36ed52d15 -- this auto rotates the 3d view to help with the grease pencil drawing -- unfortunately it's not continuous ..working on that... $\endgroup$ – zeffii Aug 19 '15 at 9:25

There are a couple ways you could go about this.

Curve object

  1. Add a curve object (I used a path, ⇧ ShiftA> Curve > Path)

  2. In edit mode (↹ Tab), extrude a vertex around randomly (⎈ CtrlLMB LMB is a fast way to extrude a vertex many times)

  3. Use the Randomize operator in edit mode to further increase randomness (Space> Randomize)

enter image description here

Grease Pencil

  1. Enable Continuous Draw in 3D view > Tool Shelf > Grease Pencil and press Draw to start drawing

  2. Draw scribbles while rotating the view at intervals

enter image description here

Once you are satisfied with your scribble, convert it to a curve object with the Convert button in the tool shelf:

Use a long strand of hair with 2 or 3 children, then use one of the styling options to randomise them, ie curl, braids etc
