Abstract
Three-dimensional (3D) reconstruction technologies have transformed the way crime scenes are documented and analyzed more than ever before, bringing major changes to the field of forensic investigations (Rangelov et al., 2024). This paradigm shift, which was first highlighted by Thali et al. in the year 2005, mainly relies on advanced 3D imaging such as computed tomography, magnetic resonance scan, surface scan, and photogrammetry. These are advanced devices that can be used to construct three dimensional crime scenes in a virtual environment to provide a permanent and detailed document of evidence that can be invaluable during the investigation and prosecution phases. The most important aspect in this regard is accurate and reliable three dimensional mapping information because the crime scene itself serves as a witness to crime as it contains the essential data and evidence that must be well gathered to uphold justice. By incorporating the newest 3D reconstruction and virtual modeling processes, the accuracy of crime scene documentation is also advanced to go beyond the two-dimensional abilities and provide a more realistic and space-oriented view of what actually transpired. This encompasses spatial scanning and visualization applications in an increasing number of forensic applications due to ongoing innovation in the interdisciplinary development to minimise bias in investigative crime and proving of culpability (Sevcik et al., 2020). These methodologies do not only allow a deeper examination of complex forensic evidence, but also introduce difficulties, especially to communicate complex spatial relationships in a courtroom context. But continued improvement on immersive technologies like virtual reality and augmented reality is starting to solve these issues of communication because they offer more intuitive and engaging visualization modalities to forensic data. These innovative methods go as far as designing electronic replicas of crime scenes, which allows capturing the entire picture of the spatial-temporal connections between the most important points and performing further simulations and animation in three dimensions. These multimodal and multiscale solutions with a mixture of 3D modeling of victims and a crime scene have some important benefits, especially in establishing one unified, extensive 3D space of all the evidence (Villa et al., 2023).
