The advent of industry 4.0 has not only brought innovation and automation with it but also new challenges. Automation in industrial settings is advancing at a rapid pace, thus making the modern industrial workplace all the more stimulating. Highly automated robots and machines work alongside humans in settings that seemed fictional some years ago. However, the shift to a smart industry has brought about certain safety concerns regarding whether the current safety systems can keep up with this ever-changing environment. Emergency stop buttons have long been the industry standard when it comes to classic safety precautions. Nevertheless, researchers examine several possibilities on how they can upgrade the already established safety systems. One such practice is to incorporate visibility as part of an emergency safety system. There has already been a proposal to use 2D visibility as an emergency safety protocol which has shown encouraging results. Thus, making a 3D approach as the logical next step. In this thesis work, a 3D visibility emergency stop system is presented, implemented,and tested. To begin with, a small review of how other researchers have tried to solve similar problems is done. Furthermore, several 3D graphics techniques used in the project are introduced and briefly analysed. Then, the implementation of the project is presented, breaking down each component. After the implementation is completed, several tests that aim to profile the program are performed and examined. In addition, the project is compared to the 2D solution that has already been proposed. The findings from the testing show that a 3D visibility approach is a viable and favourable option. The results reveal a promising outcome when it comes to object visibility as well as response swiftness.
