## createBlendBandGeometryData() function

根据 pathData 创建混合方式的 BandGeometry 所需要的数据

**Signature:**

```typescript
export declare function createBlendBandGeometryData(pathData: PathData, options: CreateBandGeometryDataOptions, preGeoData?: BandGeometryData | null): {
    position: number[];
    normal: number[];
    uv: number[];
    index: number[];
    color: number[];
    lineDistance: number[];
    lengths: number[];
    points: Vector3[];
    tangents: Vector3[];
    normals: Vector3[];
    binormals: Vector3[];
};
```

## Parameters
