Public Methods

Method Description
BeginDraw ( ) : void

This should be called at the very start of the scene rendering. The bloom component uses it to redirect drawing into its custom rendertarget, so it can capture the scene image in preparation for applying the bloom filter.
BloomComponent ( Microsoft.Xna.Framework.Game game ) : System
Draw ( GameTime gameTime ) : void

This is where it all happens. Grabs a scene that has already been rendered, and uses postprocess magic to add a glowing bloom effect over the top of it.
