Metaball Composer

by Daniel F.R. Gordillo in Scripts and Addons

The Metaball Composer addon uses different patterns to calculate the position of a metaball array, to create complex forms.

AND YES! THERE'S A 2.80 VERSION! (just upgrade it. Let me know if you experience any issues with it.)

Random pattern: Metaball clouds using simple random coordinates.

Elliptical pattern: sine/cosine elliptical spirals.

Spirograph: geometric mathematical roulette curves.

There's 2 ZIPs files available: 2.79 and 2.80 versions. Choose the one you need (or both) and install it through the user preferences window.  

The Metaball Composer will add a new submenu and 3 operators in the add -> metaball menu:


There's common settings for the 3 composition types, but elliptical and spirograph have their own specific parameters.

Common settings

  • Metaballs: number of objects in the composition
  • Pattern: List of available pattern types
  • X, Y, Z limits: Size of the composition
  • View Resolution and Render Resolution: see Blender manual
  • Scale
  • Use last metaball position: Instead of using local 0 coordinates, each metaball moves to the next position adding up previous coordinates.
  • Use Zig-Zag effect: Just a 1/-1 multiplier
  • Use 3D cursor: Use the 3D cursor as a starting point


Random pattern

 Random pattern type uses the common settings only.

There's no extra parameters.








Elliptical pattern

Elliptical pattern uses 4 functions to calculate the metaball position:

Sine, Cosine, Tangent and simple displacement


 







Spirograph

Besides the functions mentioned before, Spirograph also uses a minimum radius and a maximum radius to create the geometric patterns
