A single fluid particle in the game-layer SPH simulation.

Fields

position: Vec3

World-space position.

velocity: Vec3

Velocity (m/s).

density: f32

SPH-computed density.

pressure: f32

SPH-computed pressure.

color: [f32; 4]

RGBA colour (may drift from base over lifetime).

fluid_type: FluidType

The type of fluid.

lifetime: f32

Remaining lifetime in seconds. Particle dies when <= 0.

viscosity: f32

Per-particle viscosity.

temperature: f32

Temperature (Kelvin-ish, gameplay scale).

Implementations

impl FluidParticle

pub fn new(position: Vec3, velocity: Vec3, fluid_type: FluidType) -> Self

Create a new fluid particle.

pub fn with_lifetime(self, lt: f32) -> Self

Create a particle with a custom lifetime.

pub fn with_mass(self, m: f32) -> Self

Create a particle with a custom mass.

pub fn alive(&self) -> bool

Whether this particle is still alive.

pub fn life_fraction(&self) -> f32

Fraction of lifetime remaining (1.0 = fresh, 0.0 = dead).

pub fn speed(&self) -> f32

Speed (magnitude of velocity).
