It is proposed a computer-implemented method for designing a path connecting a first point to a second point in a three-dimensional scene. The method comprises: - providing the first point coupled with a first vector; - providing the second point coupled with a second vector; - providing a set of paths by following at the most three portions of a parallelepiped, the parallelepiped comprising the provided first point on a first vertex and the provided second point on a second vertex, a portion of the parallelepiped being an edge, a diagonal of a face, a space diagonal.
