This screencast shows the exact steps for creating two objects, utilizing the MULTIPLE OBJECT module, with a reduced vertice count spiral shell supershape acting as a mapping path for spatial data to map multiples of a arrowhead, which is just a reduced vertice version of a circle.
It is recommended to deep your vertice counts low (below 50%) on the multiple object, as the multiples are exact 3d copies of the original, and therefore exponentially increase the amount of vertices that 3L has to render. THESE ARE NOT SHADER or FX BASED MULTIPLES, so keep that in mind, because this process can slow down your machine.... WATCH YOUR VERTICE COUNT, it is not only a tool for drawing objects differently, but a FEATURE so that you can push find what your machine's limits are... With increased resolution (higher vertice count) comes a hit in performance.... so find the right balance to keep your framerate in the comfort zone.
This is the same method that was used to make the Tune On Tune In Find 3L video posted to the Made With 3L channel : vimeo.com/1148925 which uses a 3d model of a head and spheres as the multiple. Another demo of this technique, which maps a texture on to a sphere and uses the DEFORMATION module to oscillate the path object: vimeo.com/1111311
This technique is also used for 3L Flow Plus: vimeo.com/1151615 and Artificilize the Eyes: vimeo.com/1138228 . The first ever clip made using this technique to "create" a molecule can be seen at vimeo.com/1111196
