\title Chromatic Aberration
\page chromatic-aberration.html
\ingroup qt3dstudio-best-practices
In real life, chromatic aberration is an optical phenomenon causing color fringes in high contrast
areas. These color fringes are caused by different colors refracting at different angels
splitting white light into a spectrum. This is called dispersion.
In the image below, the effect is applied in the right picture.

\header
\li Property
\li Description
\row
\li
Aberration amount
\li
Amount of aberration. A negative value inverses the effect.
\row
\li
Focus depth
\li
Dispersion scales in relation to the distance from this value.
\row
\li
Effect mask
\li
A grayscale texture to control position and strength of the effect. The effect is
strongest in white areas, and weakest in black areas.
\row
\li
Debug dispersion amount
\li
Allows you to see exactly how the effect works.
\endtable
\section1 Usage
To make it easier to set up this effect, enable \uicontrol {Debug dispersion amount}. When enabled,
the scene view switches to a mode showing the amount of dispersion to be applied.
Black objects will disperse less, and white objects will disperse more.
