This sample shows different ways of performing anti-aliasing - both by using only
the native hardware AA support, and by mixing the hardware modes with additional
supersampling. There are various ways in which the supersampled image can be
down-sampled. The way we do the downsampling in this example is the same
technique that was used in 2 of our latest launch demos – “Froggy” and “Adrianne”.
This sample is a simple example on how to perform a glow effect by rendering into
an arbitrary size Frame Buffer Object (FBO).
The Glow effect is performed on a specific part of the screen and can be done only
on specific objects of the scene.
You can imagine using such a postprocessing effect in CAD/DCC to emphasize
some items from a selection or picking for example.
