This paper presents research that led to the design and implementation of fast and interactive collision detection methods that can be used to identify and report undesirable conﬂicts that occur among static (e.g., structure in-place, idle equipment), dynamic ctive machines and workers), and abstract (e.g., hazard spaces) construction resources in 3D animations of construction operations modeled using discrete-event simulation. Computational efﬁciency and interactive speed in the designed interference detection methods were the primary challenges that the research addressed. In addition, the efﬁciency and speed were achieved with minimal trade-off against accuracy. In order to achieve this, the authors capitalized on advanced documented algorithms for proximity queries between arbitrarily moving 3D geometric objects to design mechanisms for interference detection, control, and response in construction process visualizations. The designed methods are implemented in a software tool...
