Description:
This sample shows how to use bloom post-processing filters
to add a glow effect over the top of an existing scene.
Sample Overview
Bloom post-processing emulates the visual effect of bright
lights and glowing objects. It does this by extracting the brightest parts of
an image to a custom render target, blurring these bright areas, and then
adding the blurred result back into the original image.
Because bloom is implemented entirely as a post-process, it
can easily be used over the top of any other 2D or 3D rendering techniques. In
addition to the more extreme glowing effects, when used subtly it provides a
useful softening that can make computer graphics look more organic and help to
hide artifacts from elsewhere in your rendering. Particle systems, for example,
often look better with a subtle bloom applied over the top.
