Struct FxaaPass 

pub struct FxaaPass {
    pub enabled: bool,
    pub quality: FxaaQuality,
    pub shader_handle: u64,
    pub time_us: u64,
    pub custom_edge_threshold: f32,

FXAA post-processing pass.

Fields

enabled: bool

Whether FXAA is enabled.

quality: FxaaQuality

Quality preset.

shader_handle: u64

Shader program handle.

time_us: u64

Time taken for this pass (microseconds).

custom_edge_threshold: f32

Custom edge threshold override (0 = use preset).

custom_subpixel_quality: f32

Custom subpixel quality override (negative = use preset).

show_edges: bool

Whether to show edges only (debug mode).

Implementations

impl FxaaPass

pub fn new() -> Self

pub fn with_quality(self, quality: FxaaQuality) -> Self

pub fn edge_threshold(&self) -> f32

Get the effective edge threshold.

pub fn subpixel_quality(&self) -> f32

Get the effective subpixel quality.

pub fn luminance(r: f32, g: f32, b: f32) -> f32

Compute the luminance of an RGB color (sRGB-weighted).

pub fn process_pixel<F>( &self, center_x: u32, center_y: u32, width: u32, height: u32, sample: F, ) -> [f32; 3]

where F: Fn(i32, i32) -> [f32; 3],

Perform FXAA on a single pixel (CPU reference implementation). Takes a pixel sampler closure that returns (r, g, b) given (x, y) offsets.

pub fn execute(&mut self, _viewport: &Viewport)

Execute the FXAA pass (GPU simulation).

pub fn fragment_shader(&self) -> String

Generate the FXAA fragment shader.

Trait Implementations

impl Debug for FxaaPass

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

Formats the value using the given formatter.

impl Default for FxaaPass

fn default() -> Self

Returns the “default value” for a type.
