How to use the @here/harp-materials.HighPrecisionPointMaterial function in @here/harp-materials

export function createPoints(
        pointPositions: ArrayLike,
        materialParameters?: PointsMaterialParameters | HighPrecisionPointMaterial
    ): HPP.HighPrecisionPoints {
        const indices: number[] = [];

        // tslint:disable-next-line:prefer-for-of - pointPositions doesn't have iterable interface
        for (let i = 0; i < pointPositions.length; i++) {
            indices.push(indices.length / 3);
        }

        const hpPointsGeometry = new BufferGeometry();

        const hpPointsMaterial = isHighPrecisionPointMaterial(materialParameters)
            ? materialParameters
            : new HighPrecisionPointMaterial(materialParameters);

        const pointsObject = new HPP.HighPrecisionPoints(hpPointsGeometry, hpPointsMaterial);

        setPositions(pointsObject, pointPositions);

        pointsObject.setupForRendering();

        return pointsObject;
    }
}

constructor(
        geometry?: THREE.BufferGeometry,
        material?: HighPrecisionPointMaterial,
        positions?: number[] | THREE.Vector3[],

        opacity?: number
    ) {
        if (material === undefined) {
