Struct GlassSpectrum 

pub struct GlassSpectrum {
    pub angle_radians: f32,
    pub step_dp: f32,
    pub vertical_scale: f32,
    pub opacity_near: f32,
    pub opacity_far: f32,
    pub fade_depth_dp: f32,
    pub extent_dp: f32,
}

Seven-tap RGB spectrum for an edge lens. Distances follow the surface transform. Nonfinite values, negative extents, or opacities outside zero to one are ignored.

Fields

angle_radians: f32

Angle θ in radians. For outward normal (x, y), the sampling direction is (y cosθ + x sinθ, (x cosθ − y sinθ) × vertical_scale).

step_dp: f32

Signed spacing between adjacent taps, in dp; negative values reverse the colors.

vertical_scale: f32

Scale of the vertical component of the sampling direction.

opacity_near: f32

Spectral opacity at the silhouette edge.

opacity_far: f32

Spectral opacity at and beyond the fade depth.

fade_depth_dp: f32

Inward distance in dp over which opacity interpolates linearly.

extent_dp: f32

Inward distance in dp beyond which the spectrum disappears.
