Struct LiquidPose 

pub struct LiquidPose {
    pub stretch: f32,
    pub ortho: f32,
    pub axis: (f32, f32),
    pub bulge_amplitude: f32,
    pub bulge_direction: f32,
    pub speed: f32,
}

Motion-derived deformation of a liquid lens for one frame.

Fields

stretch: f32

Scale along the motion axis (>1 = elongated, <1 = compressed).

ortho: f32

Scale across the motion axis; always 1/stretch (area conserved).

axis: (f32, f32)

Unit motion direction (math convention, +x right / +y up in caller space — callers feed whatever space they draw in).

bulge_amplitude: f32

Leading-edge swell amplitude (dp) toward bulge_direction (radians).

bulge_direction: f32

speed: f32

Smoothed travel speed (dp/s) for auxiliary channels (surface depth, wobble, chromatic fringe).

Implementations

impl LiquidPose

pub fn deformation(&self) -> GlassDeformation

The full rotating strain tensor for the shader. Applying this to the signed-distance field preserves area for horizontal, vertical and diagonal travel; projecting it into an axis-aligned width/height pair cannot preserve that invariant away from the cardinal axes.

pub fn energy(&self) -> f32

Normalized motion energy in 0..1 (speed against a reference fling of ~1100 dp/s) — the shared ramp for speed-driven side channels.
