Supplementary Video 3: Gravity Sketch VR Annotation of Bloodstain Evidence in Reconstructed Indoor Crime Scene

This video is a supplementary material for the paper: "Experimental Comparison of Three-Dimensional Reconstruction Techniques for Indoor Bloodstain Crime Scene: Implications for Crime Scene Preservation and Investigator Training" ( KSFS, ISSN 1598-0715). - The video demonstrates the use of Gravity Sketch application in a VR environment (Meta Quest 3 HMD) for crime scene investigation. The footage shows the annotation capability of Gravity Sketch, including the ability to mark and highlight bloodstain zones directly within the reconstructed 3D crime scene. This feature enables forensic investigators to conduct spatial analysis and evidence marking in an immersive virtual environment based on iOS LiDAR-scanned mesh data. - This work was supported by the National Forensic Service (NFS2024FSA03).
