Many generations have tried to represent the surrounding space, oft en striving to do so in the most accurate way, precisely refl ecting details and shapes. An important step towards the faithful representation of reality was the creation of photography. Over time, the two-dimensional spatial imaging became insuffi cient, forcing the creator to choose the appropriate perspective and a comprehensive, holistic view of the object. It became possible to recreate the third dimension using two-dimensional photographs, e.g. by creating a stereogram, a panorama, or developing a 3D model. Techniques related to 3D modelling have become a very important element of contemporary photogrammetry, and they allow for an interesting, eff ective, and metrically accurate manner of depicting reality. 3D models can be used for the inventory of objects, for their reconstruction, and for their presentation. Today, there is a great need to represent the world around us in the digital space, starting from selling products whose 3D models make it possible to see that product from every side, to the creation of three-dimensional maps with street views, such as Google street view, to creating virtual city and museum walks. The products of 3D graphics are not only used for visual eff ects. The models’ metric accuracy also enables numerous engineering applications. Among other things, 3D models can be used in geodesy for inventory measurements, they fi nd their application in architecture and spatial planning, as well as in many other engineering activities related to the designing of parts, machines, and objects.
