The high spatial and temporal resolution of today's observational data of the solar corona has enabled the evolution of its physical models to a great level of detail. Even so, every instrument performs observations from a single point of view, or two since the STEREO mission, and hence the three dimensional (3D) information provided by each individual observation is r ather limited. Observational knowledge of the 3D distribution of the physical parameters of the solar corona is of great interest per se, and a key ingredient for further development of physical models. This interest has pushed the advancement of observa tional methods aimed at inferring the 3D structure of various physical parameters of the corona, based on data from different spectral ranges. In this talk we overview the current state of two 3D reconstruction methods of the solar coronal based on EUV data, namely stereoscopy and tomography. These methods can be considered as complementary, each focusing on different spatial and temporal scales. We highlight some recent results obtained with these techniques, and comment on their expected future development.
