Procedural art with Animation Nodes

Animation nodes is addon for blender, that lets you animate stuff, but it is also great for procedural art generation :).

You can get the latest version of Animation Nodes from here (click the green button for download). Support the creator of addon – Jacques Lucke – by donating here.

Update:

Below is the breakdown of the most important steps to obtain results from above (this is for advanced users).  Here is the file

  • generating random point on mesh surface (Plane object) – it will be root of spline:
  • Then I can create spline from random (x,y,z) points in loop, but this gives to noisy result (looks like lightning, jagged and random). So instead I use coherent noise – perlin noise as way of generating points for splines. This makes the splines look like wavy grass thing.
  • next step is making tip of the hairs go into direction of target object (sphere). For that I just create BHV tree for target, and then I snap spline to target with ‘find nearest surface point’. If I snap spline point to target sphere I would end up with this:

    But I do not want snap whole spline to sphere, but just the tips. To do this I can interpolate between originally generated point (x,y,z) and snapped to surface point (obtained from BHV find nearest node).

    The red inscription says: 0 == ignore snapping, 1== full snapp to target shpere). Start value in AnimFloat is root of spline, End – tip of spline.

There is more stuff, but the basic idea is explained above.

  1. Wow, thats some lovely style! I’m fascinated to know how you used AN to describe geometry in a generative manner. I was just wondering if any nice generative formulas lend themselves to drawing in Blender. Is theres any chance you could tease out some details about this work?
