- - ### Method Detail

    - #### exponent

          default float exponent()

      Returns:
        The exponent that will be used to scale the final occlusion term

    - #### noiseTexture

          R2Texture2DUsableType noiseTexture()

      Returns:
        The noise texture that will be used to peturb sampling when calculating the occlusion term

    - #### kernel

          R2SSAOKernelType kernel()

      Returns:
        The sampling kernel

    - #### sampleRadius

          default float sampleRadius()

      Returns:
        The maximum distance, in eye-space units, from which samples will be taken around each sampling point

    - #### geometryBuffer

          R2GeometryBufferUsableType geometryBuffer()

      Returns:
        The geometry buffer that will be sampled

    - #### outputBuffer

          R2AmbientOcclusionBufferUsableType outputBuffer()

      Returns:
        The ambient occlusion buffer that will contain the results of the filter operation

    - #### sceneObserverValues

          R2MatricesObserverValuesType sceneObserverValues()

      Returns:
        The observer values that were used to produce the original scene
