Program Overview

On the 3D Virtual Reality Software UC-win/Road, damage situation and its effect of shakiness and collapse of furniture and lightings mainly inside the room can be visualized in 3DVR with easy input. Shaking of furniture and fixtures is reproduced and overturning is instantly simulated by giving physical properties such as weight, center of gravity, and frictional force to objects.

The followings are the overview of these functions.

Collisions between objects are also detected. Motions such as drawers popping out of desks, and furniture colliding each other and moving another direction are also expressed. The earthquake sound and collision noise of furniture are also generated by setting sound effect to models. In addition, the seismic wave form data published by the Japan Meteorological Agency can be imported to reproduce the actual earthquakes and simulate possible seismic wave forms.

Features and Functions

●Analysis/Simulation
In the model characteristics settings, individual models can be assigned with parameters such as weight, center of gravity, and friction to instantly simulate the shaking and tumbling. In addition, the model consists of multiple parts, and when each part is selected, physical operations can be set for each part. By setting the relationship between the parts, it is possible to simulate the movement of a desk drawer, shelf door, etc.

●Flexible and high-precision expression
It can be operated on UC-win/Road, which allows expressions very close to the real space. Also, the various functions of UC-win/Road and its integration with Shade3D and other products can be used as before.

●Utilize analysis models
Simulations can be performed on a wide variety of buildings, from large facilities such as office buildings, hotels, and commercial facilities, to houses and apartment complexes (condominiums and apartments). Microscopic simulation is also possible by adding nodes for more detailed parts such as shelf drawers as needed.

Linkage with VR Motion Seat / HMD

By using the VR Motion Seat Option, it is possible to experience the shaking of an earthquake in conjunction with the VR Motion Seat. In addition, when used with HMDs such as Oculus and VIVE, a more immersive simulation can be performed.
