CLUSTER INTERACTIVE-DUALS-EXPLORING · 10 ENTRIES · EARLIEST ENTRY 2026-08-02

3D and 4D geometry visualizers

This cluster comprises interactive tools for visualizing polyhedra and higher-dimensional geometry, spanning Platonic solids, polychora, and 4D manifolds. Their dated history is too thin to read a shape from—only two dated entries exist before the index start, so the cluster predates the index or its members are undated. Traction leaders are platonic-solids (4 stars), with polychora and ShadowGeometry at 0 stars each.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 10 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

  1. 01platonic-solids4★25 dayslivehobbyInteractive web app that visualizes the five Platonic solids in 3D, shows their duals and measurements, and prints foldable nets.
  2. 02polychora0★11 days—hobbyInteractive web app for exploring 4D geometry, including regular and star polychora, Hopf fibrations, and fractals with adjustable projections and slicing.
  3. 03ShadowGeometry0★12 days—hobbyInteractive 3D visualization that unfolds a hexagonal cosmology into an icosahedron and includes a shadow-slicing tool.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
