3D Model Pack v3

The 3D models the geom="mesh" scenes load. Not part of the program: 169
models come to about 1.5 gigabytes, so they live here rather than in the
installer, the portable zip or the repository. The program builds and runs
perfectly without them.

Supersedes 3D Model Pack v2
(and v1). Take this one.

Install

1. Download whichever packs you want.
2. Unpack the .glb files straight into the program's Models folder.
3. Restart.

Any subset works. Each pack enables exactly the scenes that use it, and the
startup log says how many are still missing.

Pack	Models	Size	Contains
KaleidoscopeModels-ships.zip	77	699 MB	capital ships, freighters, couriers, drones — fly-bys, docking approaches, atmospheric entries, formations, holograms
KaleidoscopeModels-stations.zip	30	259 MB	space stations — the six station families
KaleidoscopeModels-objects.zip	62	517 MB	museum sculptures, hi-fi gear, sea creatures, eroded rock, gongs and bells, pierced lattices — and, new in v3, the real-object scenes

What changed since v2

• 21 new models for nineteen real-object scenes that used to be drawn
  procedurally and looked it: a rocket and its launch pad, a displaying
  peacock, a baroque organ, an aqueduct segment, a termite mound, a cooling
  tower, a heliostat and a solar tower, a tuning fork, a wind chime, a brass
  gear, a pendulum, a church bell, a candle, a server rack, a domino, a
  zoetrope, a metronome, a seismograph base and drum, a foundry ladle and a
  sand mould. All generated with the same pipeline as the rest of the pack
  (290k faces, 4k textures, baked normal maps).
• Light-weight variants (_lod.glb) for the models that are instanced:
  160 heliostats, 300 candles, 224 dominoes and the like are drawn from one
  buffer many times, so those carry a decimated copy of a few thousand faces.
  Both files are in the pack; the scenes reference the one they need.
• Ships and stations are unchanged from v2.

Needs v1.15.0 or newer for the nineteen new scenes — earlier releases
do not have them and simply ignore the extra files.
