 | SaoFilter Class |
Creates a Screen-Space Ambient Occlusion (SSAO) effect using the "Scalable Ambient
Obscurance" method to approximate ambient occlusion in real-time.

SyntaxThe SaoFilter type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SaoFilter |
Initializes a new instance of the SsaoFilter class.
|
Methods| Name | Description | |
|---|---|---|
| Dispose |
Releases all resources used by an instance of the PostProcessor class.
(Inherited from PostProcessor.) |
 | Dispose(Boolean) |
Releases the unmanaged resources used by an instance of the PostProcessor class
and optionally releases the managed resources.
(Inherited from PostProcessor.) |
| Equals | (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnDisable |
Called when this post-processor is disabled.
(Inherited from PostProcessor.) |
| OnEnable |
Called when this post-processor is enabled.
(Inherited from PostProcessor.) |
| OnProcess |
Called when the post-processor should perform the post-processing.
(Overrides PostProcessorOnProcess(RenderContext).) |
| Process |
Performs the post-processing using the SourceTexture
and the RenderTarget specified in the render context.
(Inherited from PostProcessor.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties| Name | Description | |
|---|---|---|
 | Bias |
Gets or sets the bias used to avoid sampling artifacts.
|
| BlurScale |
Gets or sets the blur scale.
|
| CombineWithSource |
Gets or sets a value indicating whether the ambient occlusion should be applied to the
source image - or if a black-white AO image is produced, ignoring the source image.
|
| DefaultTargetFormat |
Gets or sets the default target format.
(This property is used by the PostProcessorChain).
(Inherited from PostProcessor.) |
| EdgeSharpness | Obsolete.
Gets or sets the edge sharpness.
|
| EdgeSoftness |
Gets or sets the edge softness.
|
| Enabled |
Gets or sets a value indicating whether this post-processor is enabled.
(Inherited from PostProcessor.) |
| GraphicsService |
Gets the graphics service.
(Inherited from PostProcessor.) |
| IsDisposed |
Gets a value indicating whether this post-processor has been disposed of.
(Inherited from PostProcessor.) |
| MaxOcclusion |
Gets or sets the max ambient occlusion value.
|
| MinBias |
Gets or sets the minimum bias used to avoid sampling artifacts.
|
| Name |
Gets or sets the name of the post-processor.
(Inherited from PostProcessor.) |
| NumberOfSamples |
Gets or sets the number of samples.
|
| Radius |
Gets or sets the sample radius in world space units.
|
| SampleDistribution |
Gets or sets the sample distribution.
|
| Strength |
Gets or sets the strength of the ambient occlusion.

RemarksThis class implements SSAO using the "Scalable Ambient Obscurance" method. This method creates a higher quality result, but might be slower than the SSAO method used by the SsaoFilter.
To improve the performance of this post processor the G-Buffer 0 should be mipmapped. If the G-Buffer 0 texture does not use mip maps, then this effect might be slow with a large sampling Radius or when the scene is close to the camera.
