Function decodeOptimizedParquetGeometry

decodeOptimizedParquetGeometry(
data: ArrayBuffer,
vertexMultiplier?: number,
): Promise<MeshData[]>
Decode an optimized Parquet geometry response (ara3d BOS format).

Binary format:
- [version:u8][flags:u8]
- [instance_len:u32][mesh_len:u32][material_len:u32][vertex_len:u32][index_len:u32]
- [instance_parquet][mesh_parquet][material_parquet][vertex_parquet][index_parquet]
Key features:
- Integer quantized vertices (multiply by vertex_multiplier to get meters)
- Mesh instancing (deduplicated geometry)
- Byte colors (0-255)
- Optional normals (compute on client if not present)
Parameters
- data: ArrayBuffer
  Binary optimized Parquet response from server
- OptionalvertexMultiplier: number
  Multiplier for vertex dequantization (default: 10000)
Returns Promise<MeshData[]>
Decoded MeshData array
