Struct GlassDynamics 

pub struct GlassDynamics {
    pub activity: Option<f32>,
    pub resting_tint: Option<Color>,
    pub highlight_boost: f32,
    pub saturation_boost: f32,
    pub tint_alpha_multiplier: Option<f32>,
    pub morph: Option<GlassMorph>,
    pub touch: Option<(f32, f32, f32)>,
    pub press_depth: Option<f32>,
}

Per-frame motion inputs for an interactive glass element, read lazily at scene-build time (no recomposition per frame).

Fields

activity: Option<f32>

Continuous optical presence. None preserves the resolved material; Some(0) is an exact backdrop identity while retaining the same node, SDF, and pointer ride path.

resting_tint: Option<Color>

Base tint of the same persistent SDF surface at zero optical activity. Its alpha cross-fades out as the refractive material rises.

highlight_boost: f32

Extra specular intensity (0 = spec default; e.g. press boost).

saturation_boost: f32

Per-frame saturation added to the resolved material. Interactive surfaces use this to raise chroma without changing their base tint.

tint_alpha_multiplier: Option<f32>

Optional per-frame multiplier for the material tint alpha. Values below one clear a resting wash; values above one densify a raised tint.

morph: Option<GlassMorph>

Shape morph: when set, the glass geometry is these node-local rects instead of the node cover — the shapeshift channel.

touch: Option<(f32, f32, f32)>

Touch glow: (x_dp, y_dp, intensity) in node-local dp. A pressed surface concentrates saturation and a soft light in a radial gradient under the finger (never a flat recolor).

press_depth: Option<f32>

Dome press depth: how squashed the interactive dome is. At 1 the pressed dome refracts deep and vivid (wide rim band, strong chromatic split — the reference toggle’s gray-hold rainbow); toward 0 the released bead relaxes shallow and its split fades with it (the reference’s thin settled ring). None = 1.

Implementations

impl GlassDynamics

pub fn touched_up( self, press: f32, finger: Option<(f32, f32)>, center: (f32, f32), ) -> Self

The universal touched-up state (user-directed law): a pressed liquid surface comes closer to the user while its OWN colors go HDR-bright and saturated, with a radial glow following the finger. Never a repaint with alternate colors — the boosts amplify whatever the surface already is. press is 0..1; finger is node-local dp (falls back to center, the surface’s own heart).
