custom(Array[float]): [Read-Write] This list provides optional additional custom coefficients that can extend the existing lens model. The meaning of and how these characteristics are to be applied to a virtual camera would require negotiation between a particular producer and consumer.distortion(Array[LiveLinkOpenTrackIOLens_DistortionCoeff]): [Read-Write] A list of Distortion objects that each define the coefficients for calculating the distortion characteristics of a lens comprising radial distortion coefficients of the spherical distortion (k1-N) and (optionally) the tangential distortion (p1-N). The key ’model’ names the distortion model. Typical values for ’model’ include “Brown-Conrady D-U” when mapping distorted to undistorted coordinates, and “Brown-Conrady U-D” when mapping undistorted to undistorted coordinates. If not provided, the default model is “Brown-Conrady D-U”.distortion_offset(LiveLinkOpenTrackIOLens_DistortionOffset): [Read-Write] Offset in x and y of the centre of distortion of the virtual camera in millimeterencoders(LiveLinkOpenTrackIOLens_Encoders): [Read-Write] Normalised real numbers (0-1) for focus, iris and zoomentrance_pupil_offset(float): [Read-Write] Offset of the entrance pupil relative to the nominal imaging plane (positive if the entrance pupil is located on the side of the nominal imaging plane that is towards the object, and negative otherwise).
