\title Bloom
\page bloom.html
\ingroup qt3dstudio-best-practices
The bloom effect gives bright areas in the scene a glow effect and light bleeding to add
realism to the scene. Shortly described, all parts of the scene lighter than the
\uicontrol {Threshold of the lumino} value are extracted from the scene. Next, they are blurred,
brightened, and finally applied on top of the scene.
In the image below, the effect is applied in the right picture.
