Abstract: | 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 (e.g., active 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 called
C-Collide that integrates as an add-on with the VITASCOPE visualization system. |
