pub struct Fluid<N: RealField> {
    pub positions: Vec<Point<N>>,
    pub velocities: Vec<Vector<N>>,
    pub volumes: DVector<N>,
    pub density0: N,
    pub viscosity: N,
}

A fluid object.

A fluid object is composed of movable particles with additional properties like viscosity.

Fields

positions: Vec<Point<N>>

The world-space position of the fluid particles.

velocities: Vec<Vector<N>>

The velocities of the fluid particles.

volumes: DVector<N>

The volume of the fluid particles.

density0: N

The rest density of this fluid.

viscosity: N

The viscosity coefficient of this fluid.

Methods

impl<N: RealField> Fluid<N>

pub fn new(
    particle_positions: Vec<Point<N>>,
    particle_radius: N,
    density0: N,
    viscosity: N
) -> Self

Initializes a new fluid object with the given particle positions, particle radius, density, and viscosity.

The particle radius should be the same as the radius used to initialize the liquid world.

pub fn num_particles(&self) -> usize

The number of particles on this fluid.

pub fn particle_mass(&self, i: usize) -> N

The mass of the i-th particle of this fluid.

pub fn particle_inv_mass(&self, i: usize) -> N

The inverse mass of the i-th particle of this fluid.

Returns 0 if the i-th particle has a zero mass.
