> EXPORT

WEBM captures the canvas only - clean plate, no panel.
For a seamless loop: AUTO-ORBIT on, TIME SCALE steady.

> FRACTAL SEED

Geometry becomes the starting state - then physics animates it.

ITERATION DEPTH 3

BRANCHES PER NODE 2

SPREAD 380

> GROWTH

The structure builds itself outward, one generation at a time.

GROW OVER 6.0s

SET IT MOVING

FREEZE pins the bodies into a still structure. Any button above unfreezes it and gives the shape something to do.

> FLOW FIELD

Steers every body along a strange attractor. Turn TRAILS on.

FLOW SPEED 1.00

FLOW GRIP 10.0

> ORBITALS

Each body is one sample from the exact hydrogen probability density |ψ|². The cloud is the orbital, drawn by sampling it.

SAMPLES 900

> UNCERTAINTY

Δx·Δp ≥ ℏ/2 enforced literally. Squeeze the packet in space and the momentum spread has to grow to compensate.

LOCALISE 0.35

Δx = — · Δp = —

> DOUBLE SLIT

Landing points sampled from the real two-slit intensity. Turn TRAILS on and watch the fringes build up one particle at a time.

SLIT SEPARATION 3.0

These sample exact analytic distributions. They are honest pictures of the mathematics, not a Schrödinger solver.

> TIMELINE

0.00s / 12.00s · 0 keys

DURATION 12.0s

> KEYFRAMES

Aim the camera, then drop a key. Motion between keys is a smooth spline.

> CAMERA MOVES

One click writes a whole shot. Marked moves loop seamlessly.

> RENDER SHOT

Fixed timestep, frame by frame - the export stays smooth even if the preview stutters, and a looping move cuts seamlessly.

> DESIGN MODE

Strips every effect in one press: flat colour, no CRT, no glow, no trails, no mirroring. What you see is the raw simulation.

> SCREEN FILTER

CRT FILTER is the scanlines and vignette. BAKE paints them into the canvas so exports carry the look - it is switched on automatically while saving, and costs nothing the rest of the time.

> PERFORMANCE

RENDER SCALE 1.00

Lower RENDER SCALE first if it stutters - cost grows with pixels, not with body count. AUTO QUALITY backs off on its own below 38 FPS.

> REPRODUCIBILITY

SEED 1337

Same seed plus same shot renders identically, every time.

PHYS//LAB — free 3D physics simulator

A browser sandbox for gravity, orbits, collisions, soft bodies, fractals and strange attractors, drawn in isometric projection. Build a scene, choreograph a camera move on the timeline, export a looping animation. No install, no account, no cost.

Drag a body and let go to throw it. Right-drag orbits the camera, the wheel zooms. Try the JELLY scenario and poke the cube to watch it recover its shape.
