Struct ScatterSettings 

#[non_exhaustive]
pub struct ScatterSettings {
    pub quality: ScatterQuality,
    pub blue_noise_jitter: bool,
    pub downsample: bool,
    pub temporal: bool,
    pub temporal_blend: f32,
}

Per-frame settings for the participating-media (ScatterVolume) pass.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

quality: ScatterQuality

Quality preset. Sets the global default ray-march step count.

blue_noise_jitter: bool

Enable the blue-noise jitter on the ray-march start offset. Hides banding at low step counts at the cost of high-frequency noise that temporal accumulation would normally average out. Default true.

downsample: bool

Render the scatter pass into a half-resolution offscreen target and upsample-composite into the main HDR target. Cuts the per-pixel ray-march cost roughly to a quarter. Default false.

temporal: bool

Blend each frame’s scatter result with the previous frame’s reprojected result. Smooths out blue-noise jitter and banding over time; produces a short trail when the camera moves quickly. Default false.

temporal_blend: f32

Exponential-moving-average weight used when temporal is enabled. Larger values keep more history (smoother but laggier). Default 0.85.

Trait Implementations

impl Clone for ScatterSettings

fn clone(&self) -> ScatterSettings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ScatterSettings

impl Debug for ScatterSettings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScatterSettings

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScatterSettings

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScatterSettings

fn eq(&self, other: &ScatterSettings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ScatterSettings

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
