Struct three_d::renderer::geometry::Particles

pub struct Particles {
    pub start_positions: Vec<Vec3>,
    pub start_velocities: Vec<Vec3>,
    pub texture_transforms: Option<Vec<Mat3>>,
    pub colors: Option<Vec<Color>>,
}

Used for defining the attributes for each particle in a ParticleSystem, for example its starting position and velocity.

Each list of attributes must contain the same number of elements as the number of particles.

Fields

start_positions: Vec<Vec3>

Initial positions of each particle in world coordinates.

start_velocities: Vec<Vec3>

Initial velocities of each particle defined in the world coordinate system.

texture_transforms: Option<Vec<Mat3>>

The texture transform applied to the uv coordinates of each particle.

colors: Option<Vec<Color>>

A custom color for each particle.

Implementations

impl Particles

pub fn validate(&self) -> Result<(), RendererError>

Returns an error if the particle data is not valid.

pub fn count(&self) -> u32

Returns the number of particles.

Trait Implementations

impl Clone for Particles

fn clone(&self) -> Particles

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Particles

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Particles

fn default() -> Particles

Returns the “default value” for a type.
