Conveyor Belt Line
Products travel along a conveyor through three stations: loading, processing and quality check.
Forklift & Pedestrian Zone
Top-down view of a warehouse aisle: a forklift route crossing a marked pedestrian walkway.
Solar system
All eight planets with procedural surfaces, Saturn's rings, moons and the asteroid belt – time-lapse from today, click a planet to fly there.
Euro Pallet Load Collapse
Real rigid-body physics: an unsecured carton stack on an EPAL Euro pallet collapses after a forklift hit, hard braking or a one-sided lift. Then try the same with stretch wrap.
Stairs: Hold the Handrail
A worker walks down a workplace staircase twice: slowly with a hand on the rail, then rushing with a box. The second time, a slip turns into a physics ragdoll fall.
Globe Arcs: Ballistic Trajectories
A slowly rotating 3D Earth with glowing great-circle arcs: trajectories launch in staggered waves, travel with a fading trail and end in an impact pulse.
Laser Safety: Housing and Safety Glasses
A laser engraving cell shown twice: done right with a closed protective housing, interlock and laser safety glasses, then done wrong with the door open and a look into the reflected beam.
Cutting Machine: Light Curtain, Not Bypass
A conveyor feeds strip material through a guillotine that keeps cutting it into pieces. A hand reaches for the blade: with the light curtain active the machine makes an emergency stop, with the guard bypassed a danger warning follows.
Cake production line
Five workers in hygiene clothing decorate cakes on a conveyor: place the base, glaze, pipe dots, add a strawberry and pack into the crate.
Praline packaging line
Five workers in hygiene clothing place pralines, reject defective ones, fill boxes, put on lids and stack the boxes into a crate.
Stars within 10 light years
Rotatable 3D star map of the solar neighbourhood in galaxy-map style: real positions, galactic plane, stalks and an info card for every star.
Diels–Alder reaction
Cyclopentadiene and maleic anhydride react to the endo adduct: approach, transition state with electron arrows and bond formation in a 3D ball-and-stick model.
Tram and right-before-left
Isometric junction in St. Gallen: zebra crossing, tram, bike and the right-before-left rule – who goes when? Explained in five calm steps.
Motorway traffic jam: phantom jam, roadworks, emergency corridor
A Swiss motorway from above with many cars and trucks: how a phantom jam forms, stop-and-go, zip merging at roadworks and the emergency corridor – with a space-time diagram.
Junction 3D: who goes first? (learning card)
3D learning card in the style of Swiss driving-theory cards: right before left, “give way”, turning left with oncoming traffic and a zebra crossing – step by step with Swiss signs and arrows.
Human on the stairs (motion capture)
A realistic 3D human walks up and down a properly dimensioned staircase – with real motion-capture data, foot IK on every step, handrail use and a first “trip” fall simulation.
GPU · WindowsStrawberry cake line (GPU simulation)
The complete strawberry cake production line as a standalone Windows app: fly to every station, about 100 parts on the belt computed on the graphics card.
