MARKECHOVÁ IvetaA Notelet to Gyroid: Straight Lines InvitedA triply periodic surface gyroid (left figure) and 3D printing technology are, roughly speaking, contemporaries. Technology experts share an opinion on impossibility to produce physical model of gyroid before 3D printing era. An commonly known aesthetical attractiveness as well as wide technical applicabilities spectrum of gyroid are enriched here by our original view on mutual position of straight lines and gyroid (middle figure). Appendices offer a) some tips for involving gyroid-phenomenon to elementary course context of mathematics at technical university. Also b) challenges to meditate on correlation input-output algorithmical hierarchy if starting point is verbal prompt, for ChatGPT, to sketch of an abandoned large 3D printed gyroid model in the university yard |
