NVIDIA HBAO+ 3.0.

+

New in release 3.0

+
    +
  • Added entry points for D3D12.
    • +
  • Now shipping separate DLLs and LIB files for D3D11 and GL.
    • +
  • Replaced the DetailAO & CoarseAO parameters with NearAO & FarAO.
    • +
  • Replaced pointers with references in the API.
    • +
  • Added the ForegroundAO & BackgroundAO parameters.
    • +
  • Added per-component debug-normal visualization modes in GFSDK_SSAO_RenderMask.
    • +
  • Added support for two-pass AO blending + depth-stencil masking.
    • +
  • Removed the BLUR_RADIUS_8 mode (BLUR_RADIUS_4 looks better in general, and runs faster).
    • +
  • Removed the PER_SAMPLE_AO MSAA mode.
    • +
+

New in release 2.4

+
    +
  • Added support for Mac OS X.
    • +
  • Added the DepthClampMode parameter.
    • +
  • Added the GFSDK_SSAO_GetVersion function.
    • +
  • The input viewport and matrices are now passed by value instead of by pointer.
    • +
  • The input viewport parameter is now optional. By default, a full-resolution viewport is used.
    • +
+

New in release 2.3

+
    +
  • The input normal data are now passed by value instead of by pointer (less error prone).
    • +
  • Removed the INVALID_VIEWPORT_DIMENSIONS error code. Input viewports larger than the input textures are now supported.
    • +
  • Added support for MSAA input VIEW_DEPTHS for DX11 and GL.
    • +
  • Added support for VIEW_DEPTHS with partial input viewports for DX11.
    • +
  • Added the DepthStorage parameter in GFSDK_SSAO_Parameters.
    • +
+

New in release 2.2

+
    +
  • GL: The RenderAO call now saves & restores all the relevant GL states it alters internally.
    • +
  • GL: Added the GFSDK_SSAO_GLFunctions argument to GFSDK_SSAO_CreateContext_GL.
    • +
  • GL: Added support for MSAA input textures.
    • +
  • The GFSDK_SSAO_DRAW_DEBUG_N mode now outputs float4(-InternalViewNormal.xyz, 0).
    • +
  • Changed the blur weights of BLUR_RADIUS_2 and BLUR_RADIUS_4 to support larger sharpness values.
    • +
+

New in release 2.1

+
    +
  • Optimize the case of Params.DetailAO == 0.f and Input.pNormalData != NULL.
    • +
  • Added a parameter to control the sharpness of the optional GFSDK_SSAO_DepthThreshold.
    • +
  • GL: Added quality/performance parameters in GFSDK_SSAO_Parameters_GL.
    • +
+

New in release 2.0

+
    +
  • Added entry points for OpenGL 3.2.
    • +
  • Added support for non-zero input viewport origins.
    • +
  • Added the GFSDK_SSAO_BLUR_RADIUS_2 mode.
    • +
+

New in release 1.5

+
    +
  • Renamed the SceneScale parameter to MetersToViewSpaceUnits.
    • +
  • Added the GFSDK_SSAO_HARDWARE_DEPTHS_SUB_RANGE depth-texture type.
    • +
  • Added option to supersample the AO when using MSAA input and output textures (GFSDK_SSAO_PER_SAMPLE_AO).
    • +
  • Added PreCreateRenderTargets entry point (optional).
    • +
+

New in release 1.4

+
    +
  • Added error codes: GFSDK_SSAO_INVALID_VIEWPORT_DEPTH_RANGE and GFSDK_SSAO_UNSUPPORTED_VIEWPORT_DIMENSIONS.
    • +
  • Removed the GFSDK_SSAO_PERFORMANCE mode.
    • +
+

New in release 1.3

+
    +
  • Moved the API to a class interface.
    • +
  • Added an optional SSAO_DepthThreshold parameter, to hide potential z-buffer precision artifacts.
    • +
  • Added support for input-texture dimensions being larger than the viewport dimensions.
    • +
  • Added GFSDK_SSAO_BlurRadius option.
    • +
  • Added GFSDK_SSAO_BlurSharpnessProfile option.
    • +
  • Added GFSDK_SSAO_GPUConfiguration option.
    • +
+

New in release 1.2

+
    +
  • Merged the SetInputDepths and SetInputNormals functions into a single SetInputData.
    • +
  • Removed the SetParameters function. The parameters are now passed as an argument to RenderAO.
    • +
  • Let the user specify a BlendState for compositing the AO to the OutputRTV. See CustomBlendState.
    • +
  • Added a normal-visualization debug mode: by calling RenderAO with RenderMask = RENDER_DEBUG_NORMAL_Z.
    • +
  • Added a GetBuildString function.
    • +
