Nine minutes without intervention: the demo's course as a phase programme, which events switch the scenes, which clocks only run from then on, which fallbacks bring every run to an end, and how a single scene is checked in five minutes.
A night without filters: the exposure is fixed at the daylight value, and everything else is done by light sources. Sun, moon with a procedural disc, twinkling stars, the boat's lights after the collision regulations, a searchlight with a visible cone, and materials that do not sparkle in the video.
The camera drone as a Chrono body: four rotors, a geometric attitude controller, a setpoint follower with a braking profile, a gimbal with end stops and a battery model that decides the end of the demo.
The parasail as a multibody model: why four buoyancy points make a boat, why the line jerks by itself, why the canopy's lift has to stand perpendicular to the airflow, and how a 5 kg pilot can hang under a 95 kg canopy.
The simple visual effects of the demo, all derived from simulation quantities: tracks, spray, droplets on the glass, the wing mirror, and what they cost.
Engine, sand, sea, suspension, water entry and rotors come out of three synthesisers driven by physical quantities. The recipes, and what the ear said.
