    ■ Example 6 :  Development of a simulator for learning seaworthiness

 

 

"Generation of Irregular Wave Sea Surfaces"

- Use Unreal Engine as a 3D image development platform
- Use NVIDIA's PhysX physics engine
- Representation of sea surfaces based on physical models


"Performance Test of Ship Motion Simulation Device"

- Reproduce ship-specific motion using a 3-axis motion base
- Control of a parallel link robot
- Creation of input signals to realize 3-axis coupled motion and error evaluation regarding actual motion


"Development of Wave Models for Seaworthiness Simulators"

- Constructing a new wave model representation in C++ using Blueprint, Unreal Engine's proprietary programming tool
- This enables viewpoint movement associated with ship motion


"Research on Integration of Ship Motion Simulation and VR Goggles Imagery"

- Creation of 3D images linked between motion base and VR imagery
- SteamVR Using a plugin, it's possible to experience the same visuals when wearing VR goggles as on the motion base.


"Research on the Reproduction of Ship Hull Motion in Waves During Sailing"

- Representation of the sea surface and the space around the ship as seen from an inertial coordinate system.
- Reproduction of porpoising of a high-speed planing boat.
