Fields

position: Vec3

World-space position of the segment centre.

velocity: Vec3

Velocity (used for physics-based compression on impact).

width: f32

Half-width of the ribbon at this segment.

color: [f32; 4]

RGBA colour.

emission: f32

Emission intensity (bloom).

age: f32

Age in seconds since this segment was spawned.

pub fn update(&mut self, dt: f32)

Update the segment by dt seconds.

pub fn alpha(&self, max_age: f32) -> f32
