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

Fields

edge_return_depth_dp: Option<f32>

Independent inner return depth for an edge lens, in dp. Zero removes its depth. Nonfinite or negative values preserve the material’s default depth ratio.

optical_projection: Option<(f32, f32)>

Horizontal and vertical projection of the complete glass field about its primary center. Refraction, lighting and all scene shapes share the projection. Missing, nonfinite or nonpositive scales resolve to identity. This does not magnify the underlying backdrop.

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).

touch_radius_dp: Option<f32>

Radius of the touch glow in dp; absent, nonpositive and nonfinite values use 58 dp.

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).
