Struct GlassMorph 

pub struct GlassMorph {
    pub node_size: (f32, f32),
    pub primary: (f32, f32, f32, f32, f32),
    pub shapes: Vec<(f32, f32, f32, f32, f32)>,
    pub glue: f32,

    pub wobble_phase: f32,
    pub bulge_amplitude: f32,
    pub bulge_direction: f32,
}

A liquid shapeshift frame: the primary shape plus any number of nearby glass shapes, ALL smooth-unioned into one field — liquid glass glues to whatever glass it passes near (a growing menu necks with a neighboring button, the drag lens merges with the search circle). Up to GlassMorph::MAX_SHAPES extra shapes; an angular wobble makes the mid-flight field bubble like a droplet. All geometry is node-local dp: (center_x, center_y, width, height, corner_radius); radius sentinel -1 means capsule; -2 means SUBTRACT capsule — the shape carves a smooth hole in the field (the growing menu leaves its anchor button crisp on top until it swallows it).

Fields

node_size: (f32, f32)

The glass node’s own size in dp. The shader receives all morph geometry in dp and derives px-per-dp from the renderer-injected node pixel rect divided by this — geometry then lands correctly at ANY render scale (live window density, robot captures at 1.0, fractional desktop scales). The authoring widget always knows its node size.

primary: (f32, f32, f32, f32, f32)

shapes: Vec<(f32, f32, f32, f32, f32)>

Nearby glass shapes participating in the field.

glue: f32

Smooth-union glue radius (dp): shapes within it neck together.

wobble_amplitude: f32

Wobble amplitude (dp) and phase (radians).

wobble_phase: f32

bulge_amplitude: f32

Viscous leading-edge bulge: while the shape travels or inflates, its side facing bulge_direction (radians, math convention) swells like a pulled droplet. Amplitude in dp, usually driven by morph velocity.

bulge_direction: f32
