| |
| Note that when converting a colour from regular LSL space (sRGB) to linear space for use in a light, it's likely quicker and cleaner to use the internal function [[llsRGB2Linear]]. This is mostly a function that can be used for fun to manipulate the gamma space of colours.

| == Lens Settings ==
| |
| The below contains settings for simulating various real-life lenses within Second Life. These settings will change the camera's Field of View (FoV), as well as [[Depth of field]] (DoF) settings. You may want to play around with some of these settings (for example, the Aperture value) to manipulate the depth-of-field effect.
| |
| | |
| {{KBtip|The default Second Life camera is roughly equivalent to a full frame digital (36x24mm sensor) camera using 35mm lens.}}
| |
| | |
| For reference, the following table describes the debug settings changed, their units, and what the setting does. Default values are not provided as these settings may vary between viewers.

| |
| |-
| |
| | CameraAngle || [[Radians]] || Camera Field-of-View angle, diagonal. Equivalent to Angle of View - diagonal degrees to equate a real lens. This changes the '''visible''' FoV.
| |
| |-
| |
| | CameraDoFResScale || Linear || Amount to scale down resolution of DoF effect. Manipulating this value may change performance.
| |
| |-
| |
| | CameraFieldOfView || Degrees || Field-of-View angle used for the DoF effect. Note that this value is the '''vertical''' FoV, NOT diagonal.
| |
| |-
| |
| | CameraFNumber || F Stop || F Stop (or Aperture) value to be simulated by DoF effect. '''This is the value you should change to adjust the intensity of the DoF effect.'''
| |
| |-
| |
| | CameraFocalLength || mm || Focal length of the lens to be simulated by the DoF effect.
| |
| |-
| |
| | CameraMaxCoF || mm*1000 || Lens Circle of Confusion value to be simulated by the DoF effect.
| |
| |-
| |
| | CameraFocusTransitionTime || Seconds || Time the camera will take to transition between 2 focal planes.
