| Popis: | The present article provides an overview of the main methods of three-dimensional modelling currently used in various fields of science and practice, including forensic medicine. The possibilities of used methods are described.The authors introduce the concept of BIM-technology, which allows various methods working in 3D to be applied comprehensively: from photogrammetry and computed tomography to line-of-sight and CAD modelling. The article presents a case involving practical application of BIM-technology within the practical work of a forensic expert. The possibilities of supplementing and expanding the model over time within a single information field (4D modelling) are shown.Using the example of a specific examination, it is shown for which studies the created BIM-model can be employed, as well as what issues can be solved with its help. To that end, CT data was studied with the subsequent reconstruction of the 3D model of the damaged skull; blood traces were analysed with the subsequent 3D modelling of circumstances at the scene. The following methods were used for the reconstruction: photogrammetry, the finite element method and line-of-sight modelling of gunshot trajectories.Applied within a situational forensic medical examination, BIM-technologies successfully provided answers to the investigator’s questions: mechanism underlying the formation of blood traces; location of the bleeding source; trajectories of projectiles and their elements; circumstances of the occurrence; position of the shooter; prediction of glass breakage caused by a bullet.Conclusion. New computer technologies (BIM-technology and 4D modelling) constitute the next step in the development of three-dimensional modelling. Their introduction into the practice of experts will help create a single information field for all objects under study, as well as consider all possible investigative leads as objectively as possible |
