  • Collection of Spacefillers (SF’s)


  • Based on this book by Peter Pearce (1978), chapter 8.


  • Spidronisation of these SF’s gives some new insights into 3D tilings.


  • More details can be found in our paper published in the Bridges 2009 Conference Proceedings, or click here.
Faces of Saddle Polyhedra can be defined with Skew Polygons.
These can be filled with a minimal surface like a soap film, as Pearce did.
Or with Spidronnests. This introduces an orientation: CW or CCW (clockwise / counter-clockwise)

In general: Nests are the building blocks of Polyhedra, which can be assembled into SF’s, and to (possibly bigger) periodical Units.

Matching nests in the 3D tiling need to have opposite orientations.

    Grey: flat

    Blue: regular

    Red: mirror 4-gon

    Purple: mirror 5-gon

    Turquoise: mirror 6-gon

    Violet: mirror 8-gon

    Green: mirror 12-gon

Yellow: enantiomorphic

Method: “scale and rotate”. Nest in general not foldable.
Spidronnest orientations causes doubling compared to Pearce’s SF’s.
Cyan is CCW and Blue is CW. Projection along raster gives 2D-tilings.

  • Thanks to Peter Pearce, who described in his great book “Structure in Nature is a Strategy for Design” all the original Spacefillers, based on saddle-surfaces.


  • Thanks to all other members of the Spidron Team (amongst others: Lajos Szilassi, Rinus Roelofs, Marc Pelletier, Amina Buhler-Allen), for all their inspiring earlier work, including four earlier designs of Spidronised Spacefillers.
    (SF’s 2 , 3 , 4 and 5, all based on only regular skew polygons)


  • Thanks to András Fodor, who made this presentation.
