Struct SsgiParams 

#[repr(C)]
pub struct SsgiParams {
    pub intensity: f32,
    pub max_distance: f32,
    pub tan_half_fov_y: f32,
    pub aspect: f32,
    pub stride: f32,
    pub thickness: f32,
    pub rays: f32,
    pub steps: f32,
}

Per-frame uniform for the screen-space global-illumination (SSGI) gather + composite. Carries the clamped authored tunables and the view-ray scale the gather pass uses to project a view-space ray point back to a screen UV. Pushed verbatim to the SSGI gather + composite fragment shaders, so the layout must stay in sync with the SsgiParams struct there. 32 bytes.

Fields

intensity: f32

Indirect-bounce blend strength; scales the gathered radiance the composite pass adds on top of the existing shading.

max_distance: f32

Maximum world-space distance a hemisphere ray marches before giving up.

tan_half_fov_y: f32

tan(fov_y / 2): the vertical view-ray half-extent at unit depth.

aspect: f32

Viewport aspect ratio (width / height).

stride: f32

World-space length of one ray-march step.

thickness: f32

View-space depth tolerance for accepting a ray/scene-depth intersection.

rays: f32

Hemisphere rays cast per pixel (carried as f32; the shader reads it as an int loop bound). Backends that still bake a compile-time ray count ignore this field, so the 32-byte layout is unchanged.

steps: f32

Ray-march samples per ray (same f32-as-int-bound convention as rays).
