Ready. Set your variables and press Start.
A mirrored copy previews in green. Set the mirror line, then Confirm.
Pick a flight. Esc stops it — the camera keeps flying while you work.
Any unsaved work in the current scene will be lost.
Fast Venue's own project format isn't available yet, so there is no way to save the current scene to disk. Continue to discard everything and start fresh.

Coverage depth: near rows want a wide, down-aimed pattern; far rows a tight, near-level one. Splay, count and tilt derive from the target.
Place: click the floor once per copy — each cluster aims at the nearest audience. Esc finishes.
Copies inherit aim, gain and delay. Collision physics keeps every box legal.

- Grid & floor — world size + cell size of the visible grid.
- Units — Meters / Feet. Affects every length input app-wide.
- Theme — Dark / Light. Persists in localStorage.
- SPL color scale — see the legend gradient + the 70–110 dB clip range.
- Frequency & bandwidth — current Hz, bandwidth mode, sum mode (live).
- FR panel — axis ranges + dock hint.
- Simulation resolution — current sample area per audience triangle.

Only what falls inside this box is simulated — imported mesh and audience areas alike. Outside cells paint neutral gray.
Cinematic walkthroughs over the current scene. Each movie drives the camera and the simulation in sync — like a flying, scriptable PowerPoint.
Use Record Movie… to capture one — it will save inside the

Learn Fast Venue by playing. Each challenge is timed — beat par for ★★★.
Three optimizers race on the same physics — best average SPL over the first audience. Genes: position (x,y,z), horizontal & vertical aim.
Each bird flies with its own velocity, remembers its best spot, and chases the flock leader (global best).
The pack tracks its 3 best hunters (alpha, beta, delta) and encircles the prey. Coefficient a shrinks 2→0: roam wide, then close the kill. Almost parameter-free.
Set parameters, then Start.
Inclined surfaces is a handy trick: imported listening venues commonly model their seating as sloped faces. Picking it isolates those raked, grandstand-like surfaces for the simulation.
A 3D grid of sample points floating in the air. Each voxel is coloured by the SPL it would receive. Independent from audience areas — works with just one speaker. Always visible: when On is off (or no speakers), particles render as faint white dots for spatial reference.
- 60 fps drag: ≤ 75 k voxels × 1 band
- Settle (~tenths sec): ≤ 18 k voxels × 31 bands
- Pre-render only: > 75 k × 31 bands

Balance detail against project size. SPL cost scales with audience area × active speakers — coarser cells keep big stadium-class projects interactive.
