Distortion Map
This is a lens distortion map which makes it easier to match a specific live camera.
Camera lens distortion is sometimes done in a post-processing step but this necessitates to render images at a larger resolution, which is wasteful. Using the Distortion Map is the most efficient mean to accomplish this effect and also produces better quality. |
F-stop
Specifies the camera aperture.
Focal Length
The len's focal length, in millimeters.
Focal Distance
The distance at which objects in front of the camera will be in focus.
Projection
Projection Type
Several projection types are available. The possible values are detailed in the table below.
Option | Description |
|---|---|
| Perspective | A perspective camera. |
| Othographic | An orthographic camera. |
Cylindrical | The vertical axis uses a perspective projection. The horizontal axis uses a spherical projection. The horizontal field of view is specified by Auxiliary Field of View. |
Fisheye stereopgrahic | A stereographic fisheye projection. Maintains angles. |
| Fisheye equidistant | An equidistant fisheye projection. Maintains angular distances. |
| Fisheye equisolid | An equisolid angle fisheye projection. Maintains surface relations. |
| Fisheye orthographic | An orthographic fisheye projection. Maintains planar illuminance. |
| Spherical | A latitude/longitude spherical projection. Implies a 360 degree field of view. |
Auxiliary Field of View
Specifies the horizontal field of view, in degrees, of a Cylindrical projection. This attribute is ignored for the other projection types.
