Sets how “efficient” the shutter of the camera is at opening and closing times. ‘1.0’ is maximum efficiency, meaning that the shutter of the camera opens instantaneously, and then closes instantaneously, which is a non-natural shutter. Lower values, such as the default value of ‘0.75’, will simulate slower opening camera shutter and produces softer motion blurs, closer to what is expected in real life cameras. 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 Type Several projection types are available. The possible values are detailed in the table below. Option Description Cylindrical Fisheye stereopgrahic 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.

Perspective A perspective camera. Othographic An orthographic camera. 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. 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.
