TemporalAntiAliasingOptions

class TemporalAntiAliasingOptions

Options for Temporal Anti-aliasing (TAA).

Most TAA parameters are extremely costly to change, as they will trigger the TAA post-process shaders to be recompiled. These options should be changed or set during initialization. feedback and jitterPattern, however, can be changed at any time. A feedback of 0.1 effectively accumulates a maximum of 19 samples in steady state.

Types

enum BoxClipping : Enum<TemporalAntiAliasingOptions.BoxClipping>

Clipping algorithm for history rejection.

Properties

var boxClipping: TemporalAntiAliasingOptions.BoxClipping

Clipping algorithm. Default: BoxClipping.ACCURATE.

var boxType: TemporalAntiAliasingOptions.BoxType

Type of color gamut box. Default: BoxType.AABB.

var enabled: Boolean

Enable or disable temporal anti-aliasing. Default: false.

var feedback: Float

History feedback, between 0 (maximum temporal AA) and 1 (no temporal AA). Default: 0.12.

var filterHistory: Boolean

Whether to filter the history buffer. Default: true.

var filterInput: Boolean

Whether to apply the reconstruction filter to the input. Default: true.

var hdr: Boolean

Set to true for HDR content. Default: true.

historyReprojection

var historyReprojection: Boolean

Whether to apply history reprojection (debug option). Default: true.

var jitterPattern: TemporalAntiAliasingOptions.JitterPattern

Jitter pattern for sampling. Default: JitterPattern.HALTON_23_X16.

var lodBias: Float

Texturing LOD bias (typically -1 or -2). Default: -1.0.

preventFlickering

var preventFlickering: Boolean

Adjust the feedback dynamically to reduce flickering. Default: false.

var sharpness: Float

Post-TAA sharpening, especially useful when upscaling is true. Default: 0.0.

var upscaling: Float

Upscaling factor. Disables Dynamic Resolution. Default: 1.0 (Beta).

var useYCoCg: Boolean

Whether to use the YcoCg color-space for history rejection. Default: false.

var varianceGamma: Float

High values increase ghosting artifacts, lower values increase jittering, range 0.75, 1.25. Default: 1.0.
