The stereoscopic images obtained by the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instrument suite onboard the Solar TErrestrial RElations Observatory (STEREO), which was launched in October 2006, allow us to make 3D estimations of the structure and kinematic parameters of the dynamical solar phenomena. Among them, coronal mass ejections (CMEs) are of a great importance as they are very energetic, complex phenomena, which, when interacting with the Earth magnetic field can produce major disturbances affecting us directly. This is why it is important to know in advance their kinematic properties and their 3D shape, as well as the properties of the medium through which they propagate. We will present in this talk an update of what was done so far on this aspect. We will outline the constraints on reconstructing the CMEs and possible improvements with the next generation of space missions.
