Outputs
| Type | Name | Description |
|---|---|---|
| real | Custom | This list provides optional additional custom coefficients that can extend the existing lens model. The meaningof and how these characteristics are to be applied to a virtual camera would requirenegotiation between a particular producer and consumer. |
| struct | Distortion | A list of Distortion objects that each define the coefficients for calculating the distortion characteristics of a lens comprising radialdistortion coefficients of the spherical distortion (k1-N) and (optionally) the tangential distortion (p1-N). The key ?model? names thedistortion model. Typical values for ?model? include "Brown-Conrady D-U" when mapping distorted to undistorted coordinates, and "Brown-ConradyU-D" when mapping undistorted to undistorted coordinates. If not provided, the default model is "Brown-Conrady D-U". |
| struct | Distortion Offset | Offset in x and y of the centre of distortion of the virtual camera in millimeter |
| struct | Encoders | Normalised real numbers (0-1) for focus, iris and zoom |
| real | Entrance Pupil Offset | Offset of the entrance pupil relative to the nominal imaging plane(positive if the entrance pupil is located on the side of the nominalimaging plane that is towards the object, and negative otherwise).Measured in meters as in a render engine it is often applied in thevirtual camera?s transform chain. |
| struct | Exposure Falloff | Coefficients for calculating the exposure fall-off (vignetting) of a lens |
| struct | FStop | The linear f-number of the lens, equal to the focal length divided by the diameter of the entrance pupil. |
| struct | Pinhole Focal Length | Distance between the pinhole and the image plane in the simple CGI pinhole camera model. (millimeters) |
| struct | Focus Distance | Focus distance/position of the lens in meters. |
| struct | Projection Offset | Offset in x and y of the centre of perspective projection of the virtual camera |
| struct | Raw Encoders | Raw encoder values. |
| struct | TStop | T-stop: Linear t-number of the lens, equal to the F-number of the lens divided by the square root of the transmittance of the lens. |
