Struct for dynamic (per-frame) OpenTrackIO data

C++ Source:

  • Plugin: LiveLinkOpenTrackIO

  • Module: LiveLinkOpenTrackIO

  • File: LiveLinkOpenTrackIOLiveLinkTypes.h

Editor Properties: (see get_editor_property/set_editor_property)

  • aperture (float): [Read-Write] Aperture of the camera in terms of f-stop

  • aspect_ratio (float): [Read-Write] Aspect Ratio of the camera (Width / Heigth)

  • distortion_parameters (Array[float]): [Read-Write] Parameters used by the distortion model

  • field_of_view (float): [Read-Write] Field of View of the camera in degrees

  • film_back_height (float): [Read-Write] Used with CinematicCamera. Values greater than 0 will be applied if bIsDynamicFilmbackSupported is true on static data.

  • film_back_width (float): [Read-Write] Used with CinematicCamera. Values greater than 0 will be applied if bIsDynamicFilmbackSupported is true on static data.

  • focal_length (float): [Read-Write] Focal length of the camera

  • focus_distance (float): [Read-Write] Focus distance of the camera in cm. Works only in manual focus method

  • fx_fy (Vector2D): [Read-Write] Normalized focal length used by the distortion model

  • meta_data (LiveLinkMetaData): [Read-Write] Frame’s metadata.

  • open_track_data (LiveLinkOpenTrackIOData): [Read-Only] Access to the received OpenTrackIO data

  • principal_point (Vector2D): [Read-Write] Normalized center of the image, in the range [0.0f, 1.0f]

  • projection_mode (LiveLinkCameraProjectionMode): [Read-Write] ProjectionMode of the camera (Perspective, Orthographic, etc…)

  • property_values (Array[float]): [Read-Write] Values of the properties defined in the static structure. Use FLiveLinkBaseStaticData.FindPropertyValue to evaluate.

  • timestamps (Map[Name, double]): [Read-Only] This frame timestamps used for measuring latency

  • transform (Transform): [Read-Write] Transform of the frame

  • world_time (LiveLinkWorldTime): [Read-Only] Time in seconds the frame was created.

property open_track_data: LiveLinkOpenTrackIOData

[Read-Only] Access to the received OpenTrackIO data
