Due to its proximity, the Sun is studied with a much higher spatial and temporal resolution than the rest of the stars. The abundant availability of observational solar data has allowed the development of solar models of a high complexity level. Even so, every instrument per- forms observations from a single point of view, or two since the STEREO mission, and hence the three-dimensional (3D) information of each indi- vidual observation is rather limited. Knowledge of the 3D distribution of the solar physical parameters is of great interest per se, as well as to the development of models. This interest has pushed forward the devel- opment of a variety of methods to infer the 3D structure of the physical parameters that are derived from observations in different spectral ranges. In this talk we overview the current state of the 3D reconstruction meth- ods of the solar corona based on EUV data. We will focus on stereoscopy and tomography, which are complementary techniques, each focusing on different spatial and temporal scales. We highlight some results obtained with these techniques, and discuss on the expected future development of them.
