When we design and construct a large-scale device, it is very important to confirm the interference among its parts. We might need to confirm not only the interference among the parts that are designed at the start but also the interference with some parts that are added after construction. However, sometimes even on using 3D CAD, we cannot detect the interference or the collision among parts, particularly when these parts form a complex 3D shape. On the other hand, virtual reality devices have been used in various fields such as design support systems; however, real-time collision detection among complex parts has been difficult to achieve. We constructed a system that can detect collision and interference in real time in a virtual reality system.

在设计和建造大型设备时，确定其各部件之间的干涉是非常重要的。我们可能不仅需要确认在开始时设计的零件之间的干涉，还需要确认与施工后添加的某些零件之间的干涉。然而，有时即使使用3D CAD，我们也无法检测到零件之间的干涉或碰撞，特别是当这些零件形成复杂的3D形状时。另一方面，虚拟现实设备已被用于各种领域，如设计支持系统，然而，复杂的零件之间的实时碰撞检测一直难以实现。在虚拟现实系统中，构建了一个能够真实的实时检测碰撞和干涉的系统。
