**Signature:**

```typescript
export declare function connectBandGeometryData(frontData: BandGeometryData, backData: BandGeometryData, options: CreateBandGeometryDataOptions, lengthConnectType?: LengthConnectType): {
    position: number[];
    normal: number[];
    uv: number[];
    color: number[];
    lineDistance: number[];
    index: number[];
    points: Vector3[];
    lengths: number[];
    length: number;
    tangents: Vector3[];
    normals: Vector3[];
    binormals: Vector3[];
};
