Enumerations

FfxSssrPass

enum FfxSssrPass

An enumeration of all the passes which constitute the SSSR algorithm.

SSSR is implemented as a composite of several compute passes each computing a key part of the final result. Each call to the FfxSssrScheduleGpuJobFunc callback function will correspond to a single pass included in FfxSssrPass. For a more comprehensive description of each pass, please refer to the SSSR reference documentation.

Values:

FFX_SSSR_PASS_DEPTH_DOWNSAMPLE

FFX_SSSR_PASS_DEPTH_DOWNSAMPLE = 0

A pass which performs the hierarchical depth buffer generation.

FFX_SSSR_PASS_CLASSIFY_TILES

FFX_SSSR_PASS_CLASSIFY_TILES = 1

A pass which classifies which pixels require screen space ray marching.

FFX_SSSR_PASS_PREPARE_BLUE_NOISE_TEXTURE

FFX_SSSR_PASS_PREPARE_BLUE_NOISE_TEXTURE = 2

A pass which generates an optimized blue noise texture.

FFX_SSSR_PASS_PREPARE_INDIRECT_ARGS

FFX_SSSR_PASS_PREPARE_INDIRECT_ARGS = 3

A pass which generates the indirect arguments for the intersection pass.

FFX_SSSR_PASS_INTERSECTION

FFX_SSSR_PASS_INTERSECTION = 4

A pass which performs the actual hierarchical depth ray marching.

FFX_SSSR_PASS_COUNT

Source: sdk/include/FidelityFX/host/ffx_sssr.h (line 75, column 1)

FfxSssrInitializationFlagBits

enum FfxSssrInitializationFlagBits

An enumeration of bit flags used when creating a FfxSssrContext. See FfxSssrContextDescription.

Values:

FFX_SSSR_ENABLE_DEPTH_INVERTED

FFX_SSSR_ENABLE_DEPTH_INVERTED = (1 <<0)

A bit indicating that the input depth buffer data provided is inverted [1..0].
