Optical System
Optical System
The Optics section of the UVR Camera Settings component defines the lens of the sensor :
The Lens Radius is the radius of the optical system : a large radius means more blur and a small radius less blur.
The Focus Distance is the distance at which the image will be sharp : an object that is seen from a distance similar to the focus distance will be sharp, an object that is seen from closer/further away will be blurred.
If the Lens Radius is set to 0, a model pinhole camera is used and the image is the sharpest.
The focus distance and lens radius are expressed in the same unit as the scene. See the scene section for more details on units.
The optical system settings can be edited at run time.
