@Override
    public void getRandomPointAndNormal(Vector3f store, Vector3f normal) {
        store.set(point);
    }
For a point shape, the generated point is always the shape's defined point.
The normal is not defined for a point shape, so this method does not modify the normal parameter.

@param store  The {@link Vector3f} to store the generated point in.
@param normal The {@link Vector3f} to store the generated normal in (unused).
