Select this device to communicate with a camera that streams tracking information using the Stype protocol.
Settings
| Property | Default | Description |
|---|---|---|
| Name | OpenVR | User-friendly name. |
| Enable | ON | Toggle to enable/disable the device. |
| Run at startup | ON | Toggle to enable the device when Kinetic Designer is launched. |

Find pose |
– | Click to find the camera pose (position + orientation) in the world frame that typically corresponds to the origin of the 3D scene. If the camera is mounted on a moving trackable device (such as ActivePuck), it is possible to compute the camera pose in relation to a node in the 3D scene. To do this, drag & drop the proper node in the corresponding field. Note : The pose of the camera is often referred to as ground transform. |
| Use find pose | ON | Toggle to activate/deactivate the transformation found using the Find pose button. |
| Position (x,y,z) | (0.0 ; 0.0 ; 0.0) | Displays the current position of the camera. Each parameter (x, y, and z) can be individually toggled to activate/deactivate them. If the parameter is deactivated the device will not update this value in the 3D camera/projector associated with this device. (in the 3D view) |
| Rotation (x,y,z) | (0.0 ; 0.0 ; 0.0) | Displays the current rotation of the camera. Each parameter (x, y, and z) can be individually toggled to activate/deactivate them. If the parameter is deactivated the device will not update this value in the 3D camera/projector associated with this device. (in the 3D view) |
| 3D Camera | - | Drag & Drop a camera from a 3D scene to associate it with this device. When associated, the motion of the real camera will be mapped to move the camera in the 3D scene. You can add as many cameras as you want. As soon as you drag & drop a camera in the field, a new empty one will be created. |
Lens tab
| Property | Default | Description |
|---|---|---|
| Display | ||
| Horizontal FOV | 0.0° | Horizontal field of view in degrees. |
| Aspect | 1.0 | Ratio between image’s width and height. |
| Horizontal shift | 0.0% | Horizontal shift of the lens center (percentage of image width). |
| Vertical shift | 0.0% | Vertical shift of the lens center (percentage of image height). |
| Distortion, k1 | 0.0 | Distortion parameter proportional to the distance from lens center (r^2). |
| Distortion, k2 | 0.0 | Distortion parameter proportional to the squared distance from lens center (r^4). |

Stype tab
| Property | Default | Description |
|---|---|---|
| Port | 11311 | TCP/IP port used by the device. |
| Tracking delay, ms | 0 | Generally there is a small desynchronization between the image and tracking information. This parameter enables the user to compensate it by delaying the incomming Stype data. |
| Display | ||
| Pan | 0.0° | Value of pan in degrees received by Stype protocol |
| Tilt | 0.0° | Value of tilt in degrees received by Stype protocol |
| Roll | 0.0° | Value of roll in degrees received by Stype protocol |
| X | 0.0 | Camera x position in meters received by Stype protocol |
| Y | 0.0 | Camera y position in meters received by Stype protocol |
| Z | 0.0 | Camera z position in meters received by Stype protocol |
| Zoom | 0.0 | Camera zoom received by Stype protocol (typically in a range from 0 to 1) |
| Focus | 0.0 | Camera focus received by Stype protocol (typically in a range from 0 to 1) |
