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.

Protected Methods

Method	Description
LoadContent ( ) : void	Load your graphics content.
UnloadContent ( ) : void	Unload your graphics content.

Private Methods

Method	Description
ComputeGaussian ( float n ) : float	Evaluates a single point on the gaussian falloff curve. Used for setting up the blur filter weightings.
DrawFullscreenQuad ( Microsoft.Xna.Framework.Graphics.Texture2D texture, RenderTarget2D renderTarget, Effect effect, IntermediateBuffer currentBuffer ) : void	Helper for drawing a texture into a rendertarget, using a custom shader to apply postprocessing effects.
DrawFullscreenQuad ( Microsoft.Xna.Framework.Graphics.Texture2D texture, int width, int height, Effect effect, IntermediateBuffer currentBuffer ) : void	Helper for drawing a texture into the current rendertarget, using a custom shader to apply postprocessing effects.
SetBlurEffectParameters ( float dx, float dy ) : void	Computes sample weightings and texture coordinate offsets for one pass of a separable gaussian blur filter.
