Real-time Rendering에서의 Collision Detection에 대한 구현은 Detection에 대한 정보를 읽고, 인지하는 정도에 그쳤으나, Vortex에서 제공하는 Physical Dynamic을 위한 Detection에 대한 기능으로 한층 사실감 있는 영상의 구현이 가능하게 되었습니다.
지금까지 VR Application이 안고있던 문제점 중의 하나였던 Collision Detection이나 Collision response에 대한 정보를 Vortex가 손쉽게 제공해 주게됨으로써 Real-time VR의 사실적인 구현까지 그 Level을 한단계 올려주는 역할을 주도하게 되었다. |
|
|
Vortex에서 제공하는 Collision Detection | |
| Fast collision detection with accurate contact response. |
| Geometry types include primitives, meshes and composites. |
| Terrain support: triangle meshes, heightfields or triangle lists. |
| Near field collision detection and collision geometry level-of-detail. |
| State-of-the-art mesh collision detection using oriented bounding boxes (OBB) and far field culling. |
| Collision queries for all objects including normals, penetration distance and surface separation distance. |
| Built-in time of impact estimates. |

Land Vehicles | |
|
|
 |
|
| Stryker |
|
| Vortex high-fidelity vehicle dynamics were used to simulate the Stryker personnel carrier. Simulated behaviors include variable gear ratios, tire-terrain tracking, suspension, steering, obstacle impact and force reaction. | |
|
 |
|
| M1 Abrams Battle Tank |
|
| This Vortex-enabled tank can roll over rough terrain and various obstacles with great accuracy. Multiple gear ratios and variable transmission rates give the tank realistic driving behavior. The turret and barrel are fully articulated. Comprehensive vehicle dynamics include suspension, steering effects, and tread models. | |
|
 |
|
| Hummer |
|
| The rugged Vortex hummer makes simulated driving seem real. The hummer features accurate vehicle handling, full contact friction and terrain interaction, variable acceleration based on gear ratios, and realistic tire slip models. Vortex dynamics will handle any type of land-based driving vehicles, both manned and unmanned. | |

Industrial Machines | |
|
|
 |
|
| Log Forwarder |
|
| Simlog, a leading developer of operator trainers, relied on Vortex to simulate a physically realistic logging machine. Vortex calculates the position, orientation and interaction of the machine with the logs in a realtime 3D environment. "Vortex is a great piece of software engineering", says Paul Mackenzie, Vice-President, Product Development. | |
|
 |
|
| Mobile Crane |
|
|
The mobile crane illustrates how Vortex can be used to accurately model articulated machines such as cranes and can simulate including cables, flex in retractable booms and powered motors. Note how the vehicle reacts to the weight and dimensions of the boxes. | |
|
 |
|
| Reach Stacker |
|
| This demo and video demonstrate how Vortex is used to simulate correct behavior of an articulated machine as it grasps, lifts and carries containers. Vehicle handling is directly impacted by the size and weight of the container. Once a container is lifted, mass and inertial properties cause it to swing back and forth. | |
|
 |
|
| Tree Harvester |
|
| Jointly developed by Oryx Simulations and the CMLabs Professional Services Team, this trainer is used around the world. Vortex was used to model correct machine behaviors including gear shifting and engine power, tire-terrain tracking, hydraulics and the grapple head. | |
