public static java.awt.geom.Point2D.Double getTextureCoordinate(Vector3D vector)
```
    Returns the point of the texture image that is mapped to the given point in 3D space (given as Vector3D) See the Wikipedia article on UV mapping.
    
    Parameters:
    
    vector - the vector to which the texture point is mapped
    
    Returns:
    
    a point on the texture image somewhere in the rectangle between (0, 0) and (1, 1)

```
public static Vector3D getVector(double u,
                                 double v)
```
    For a given point of the texture (i.e. the image), return the point in 3D space where the point of the texture is mapped to (as Vector3D).
    
    Parameters:
    
    u - x-coordinate of the point on the texture (in the range between 0 and 1, from left to right)
    
    v - y-coordinate of the point on the texture (in the range between 0 and 1, from top to bottom)
    
    Returns:
    
    the vector from the origin to where the point of the texture is mapped on the sphere
