Four-dimensional geometry, live in your viewport

Blender 4.5+ · 70 Curated Polytopes · One-Time Purchase · Instant Download

Blender models three dimensions. This add-on gives it a fourth. Spawn a real 4-dimensional polytope, rotate it through the planes that don't exist in our space, and watch its 3D shadow turn itself inside out — live in the viewport, not baked in advance.

A tesseract in the Neon Gradient style, rendered straight out of the included demo file. The gradient runs from the polytope's centre outward, so the inner cell reads cyan and the outer shell yellow.

The add-on in Blender: one sidebar panel holds the searchable shape library, the six 4D rotation planes and their animation speeds, projection, cross-section, Loop Studio and the exports. Nothing lives in a separate window.

What It Does

True 4D rotation

Rotate in the XW, YW and ZW planes — the ones that couple our three dimensions to the fourth — and project down with your choice of stereographic or perspective projection. The inside-out morph is the real thing, computed in 4D, not a 3D animation imitating one.

Animated cross-sections

Slice a 4D solid with a moving hyperplane and watch the 3D cross-section shift as it passes through — a tesseract resolving into an exact cube, a 600-cell blooming into two hundred faces. Combines freely with rotation for a slice that turns as it cuts.

Four stages of a hyperplane sweeping through a 120-cell, the solid cross-section growing from a small polyhedron to a large rounded one
Four steps of a hyperplane passing through a 120-cell. Each frame is a genuine 3D solid — the slice is recomputed from the 4D cell data, not morphed between shapes.
Seamless Loop Studio

One click sets frame count, turn count and motion preset — isoclinic, simple, double or spin-tumble — so the last frame reproduces the first exactly. Perfect loops for reels and installations, without hand-tuning keyframes.

A curated shape library

70 hand-picked polytopes in a searchable browser: every convex regular 4D solid, the regular stars, classic truncates and rectifieds, the grand antiprism, the snub 24-cell and five compounds. Point the add-on at your own folder to load more.

Several at once

Every polytope carries its own state, so a scene can hold many, each rotating on its own axes at its own speed. Build comparisons, arrays and full compositions.

Two 4D polytopes in one scene — a 24-cell in perspective projection beside a 16-cell in stereographic projection, each glowing in the neon style

Render-ready styles

Neon Gradient — glowing tubes, graded radii, black world, bloom — for the look on the box. Wireframe Ink — black strokes on white, uniform width — for print and plotting. Both are one dropdown away.

A 600-cell in stereographic projection rendered in the Wireframe Ink style — fine black curves on white, the density of a copperplate engraving
The same engine in Wireframe Ink: a stereographic 600-cell as flat black strokes on white. This is the style the centerline SVG and DXF exports are built around.
Exports that leave Blender

Freeze any frame to a standalone mesh, or send it out as STL or GLB. Bake an animation to USD curves. And export the projected edge skeleton as centerline SVG or DXF R12 — one clean stroke per edge, which is what a pen plotter or a laser actually wants, rather than the doubled outlines a silhouette pass produces.

In the Download

The add-on as a Blender extension zip, a quick-start guide, a feature reference, and four demo .blend files — a neon loop, a 120-cell cross-section sweep, a plotter-ink vector export stage, and a multi-polytope scene — each set up and ready to render.

Requirements

Blender 4.5 or newer, on Windows, macOS or Linux. Tested against 4.5.3 LTS, 5.1.2 and 5.2. No external dependencies, no account, no subscription, and nothing phones home. Install it the way you install any extension.

Built by Pardesco over several years of making 4D work — the same engine behind our own polytope films and sculpture. Sold once, owned outright.
