Summon a mathematical solid, then bend it with light and motion. Try the controls — this is the real renderer.
Athena turns pure geometry into a living scene. Tap to summon, drag to arrange, and let effects run while you compose.
From the five Platonic solids to Archimedean, Catalan, Kepler–Poinsot and Johnson — every shape derived from clean geometry.
Spin, colour harmonies, explode, glowing shells and 30+ particle trails — all live, all at once.
Shoot a photo or record video straight from the scene, then save and share.
A SwiftUI surface floats over the SceneKit scene: pick a tool from the strip, dial it in on the right dock, and group your solids with selectable chips.
Effects are stored per object and per group, so a single scene can hold dozens of solids each doing their own thing — and every value saves with the file.
Tumble, or lock to X · Y · Z, with a per-layer stagger.
14 wheel patterns — Rainbow, Golden, Triadic, Neon, Ice — recolour the whole set live.
Blow faces outward in up to six nested layers, with spacing and fade.
A stack of glowing cages that follow the shape — pulse, breathe, rotate, rainbow.
Over 30 types — comet, fire, plasma, lightning, chromatic — plus zoom-reactive warps.
Five channels multiply: per-object, Fibonacci, Euler density, Kepler nesting, F/V duality.
Orbit a whole cluster about its centroid; reverse it, or tilt freely with two fingers.
Send a group along an XYZ route — "beads on a wire" — looping or one-shot.
Steer the key light by azimuth and elevation; push object luminance into bloom.
SD · HD · Ultra — antialiasing and supersampling on tap.
Trails react to the camera — warp streaks, vortex and burst on zoom.
Whole-scene snapshots to .athena, reloaded exactly as they were.
Coordinate tables are where errors hide. So Athena hand-types only the tetrahedron, cube, octahedron and icosahedron — then grows the whole catalog with a handful of geometric operators.
The icosahedron's twelve vertices are just the cyclic permutations of one pair of numbers — built from the golden ratio:
Operators always produce correct topology. The geometry comes out clean and consistent — exactly what an art tool needs, without a brittle table of hand-keyed coordinates for the whole catalog.
All faces the same regular polygon; every vertex identical.
Two or more regular polygons, every vertex identical. Two snubs still to come.
The dual of an Archimedean — every face congruent, vertices vary.
Regular star polyhedra with star-polygon faces or vertex figures.
Convex, regular-faced, non-uniform — a procedural subset, built piece by piece.
Swap every face for a vertex. Turns an icosahedron into a dodecahedron.
Rectify — cut to edge midpoints. The route to most Archimedeans.
Slice off each corner, opening a new face where a vertex was.
Raise a pyramid on every face — the basis of the star forms.
Bevel every edge into a hexagon — the Goldberg-style geodesic operator.
The Johnson family is the exception to the operator chain — its pyramids, cupolas and bipyramids are composed procedurally, piece by piece (13 in the catalog so far, of 92 known).
V − E + F = 60 − 90 + 32 = 2 ✓
Frame it, hit record, and walk away with a file ready to post. Athena keeps your work safe, frame by frame.
.athena and reload it exactly as it was.Built in SwiftUI over SceneKit with zero third-party dependencies — so it stays fast, native, and entirely yours.
Athena is coming to iPad. Bring the geometry — we'll bring the light.
