Functions

ffxFsrPopulateEasuConstants

FFX_STATIC void ffxFsrPopulateEasuConstants(FFX_PARAMETER_INOUT FfxUInt32x4 con0, FFX_PARAMETER_INOUT FfxUInt32x4 con1, FFX_PARAMETER_INOUT FfxUInt32x4 con2, FFX_PARAMETER_INOUT FfxUInt32x4 con3, FFX_PARAMETER_IN FfxFloat32 inputViewportInPixelsX, FFX_PARAMETER_IN FfxFloat32 inputViewportInPixelsY, FFX_PARAMETER_IN FfxFloat32 inputSizeInPixelsX, FFX_PARAMETER_IN FfxFloat32 inputSizeInPixelsY, FFX_PARAMETER_IN FfxFloat32 outputSizeInPixelsX, FFX_PARAMETER_IN FfxFloat32 outputSizeInPixelsY)

Setup required constant values for EASU (works on CPU or GPU).

Parameters:

  • con0 (FFX_PARAMETER_INOUT FfxUInt32x4) – [out]
  • con1 (FFX_PARAMETER_INOUT FfxUInt32x4) – [out]
  • con2 (FFX_PARAMETER_INOUT FfxUInt32x4) – [out]
  • con3 (FFX_PARAMETER_INOUT FfxUInt32x4) – [out]
  • inputViewportInPixelsX (FFX_PARAMETER_IN FfxFloat32) – [in] The rendered image resolution being upscaled in X dimension.
  • inputViewportInPixelsY (FFX_PARAMETER_IN FfxFloat32) – [in] The rendered image resolution being upscaled in Y dimension.
  • inputSizeInPixelsX (FFX_PARAMETER_IN FfxFloat32) – [in] The resolution of the resource containing the input image (useful for dynamic resolution) in X dimension.
  • inputSizeInPixelsY (FFX_PARAMETER_IN FfxFloat32) – [in] The resolution of the resource containing the input image (useful for dynamic resolution) in Y dimension.
  • outputSizeInPixelsX (FFX_PARAMETER_IN FfxFloat32) – [in] The display resolution which the input image gets upscaled to in X dimension.
  • outputSizeInPixelsY (FFX_PARAMETER_IN FfxFloat32) – [in] The display resolution which the input image gets upscaled to in Y dimension.

Returns: FFX_STATIC void
