Class FSRUtils
Utility functions relating to FidelityFX Super Resolution (FSR)
These functions are expected to be used in conjuction with the helper functions provided by FSRCommon.hlsl.
Namespace: UnityEngine.Rendering
Syntax
public static class FSRUtilsMethods
IsSupported()
Returns true if FidelityFX Super Resolution (FSR) is supported on the current system
FSR requires the textureGather shader instruction which wasn't supported by OpenGL ES until version 3.1
Declaration
public static bool IsSupported()Returns
| Type | Description |
|---|---|
| Boolean | if FSR is supported on the current system |
SetEasuConstants(CommandBuffer, Vector2, Vector2, Vector2)
Sets the constant values required by the FSR EASU shader on the provided command buffer
Logic ported from "FsrEasuCon()" in Runtime/PostProcessing/Shaders/ffx/ffx_fsr1.hlsl
Declaration
public static void SetEasuConstants(CommandBuffer cmd, Vector2 inputViewportSizeInPixels, Vector2 inputImageSizeInPixels, Vector2 outputImageSizeInPixels)Parameters
| Type | Name | Description |
|---|---|---|
| CommandBuffer | cmd | Command buffer to modify |
| Vector2 | inputViewportSizeInPixels | This the rendered image resolution being upscaled |
| Vector2 | inputImageSizeInPixels | This is the resolution of the resource containing the input image (useful for dynamic resolution) |
| Vector2 | outputImageSizeInPixels | This is the display resolution which the input image gets upscaled to |
SetRcasConstants(CommandBuffer, Single)
Sets the constant values required by the FSR RCAS shader on the provided command buffer
Logic ported from "FsrRcasCon()" in Runtime/PostProcessing/Shaders/ffx/ffx_fsr1.hlsl
Declaration
public static void SetRcasConstants(CommandBuffer cmd, float sharpness = 0.2F)Parameters
| Type | Name | Description |
|---|---|---|
| CommandBuffer | cmd | Command buffer to modify |
| Single | sharpness | The scale is {0.0 := maximum, to N>0, where N is the number of stops(halving) of the reduction of sharpness |
