    count: number,
    areaSize: number,
    heightFunc: (x: number, z: number) => number,
    biomes?: BiomeData[],
    allowedBiomes?: string[],
    seed?: number,
): InstanceData[]
Generate instance data (positions, rotations, scales) based on biomes.
Parameters
- count: number

- Optionalbiomes: BiomeData[]
  Array of biome data for distribution.
- OptionalallowedBiomes: string[]
  List of biome types this instance can spawn in.
- Optionalseed: number
  Random seed for deterministic placement.
Returns InstanceData[]
Array of InstanceData objects.
Example
```
const trees = generateInstanceData(
  500,
  100,
  (x, z) => getTerrainHeight(x, z),
  biomes,
  ['forest']
);
