Struct three_d::renderer::object::Particles

pub struct Particles {
    pub acceleration: Vec3,
    pub time: f32,
    // some fields omitted
}

Particle effect that can be rendered with any material.

Each particle is initialised with a position and velocity using the update function and a global acceleration. Then when time passes, their position is updated based on new_position = start_position + start_velocity * time + 0.5 * acceleration * time * time

Fields

acceleration: Vec3

The acceleration applied to all particles. Default is gravity.

time: f32

A time variable that should be updated each frame.

Implementations

impl Particles

pub fn new(context: &Context, cpu_mesh: &CPUMesh) -> ThreeDResult<Self>

Creates a new set of particles with geometry defined by the given cpu mesh.

pub fn update(&mut self, data: &[ParticleData])

Updates the particles with the given initial data. The list contain one entry for each particle.

Trait Implementations

impl Geometry for Particles

fn aabb(&self) -> AxisAlignedBoundingBox

Returns the AxisAlignedBoundingBox for this geometry.

fn transformation(&self) -> Mat4

Returns the local to world transformation applied to this geometry.

impl GeometryMut for Particles

fn set_transformation(&mut self, transformation: Mat4)

Set the local to world transformation applied to this geometry.

impl Shadable for Particles

fn render_with_material(
    &self,
    material: &dyn Material,
    camera: &Camera,
    lights: &Lights
) -> ThreeDResult<()>

Render the object with the given material. Must be called in a render target render function, for example in the callback function of Screen::write. You can use Lights::default() if you know the material does not require lights.

fn render_forward(
    &self,
    material: &dyn Material,
    camera: &Camera,
    lights: &Lights
) -> ThreeDResult<()>

👎 Deprecated:

use render_with_material instead

Render the object with the given material. Must be called in a render target render function, for example in the callback function of Screen::write. You can use Lights::default() if you know the material does not require lights.

fn render_deferred(
    &self,
    _material: &DeferredPhysicalMaterial,
    _camera: &Camera,
    _viewport: Viewport
) -> ThreeDResult<()>

👎 Deprecated

Render the geometry and surface material parameters of the object. Should usually not be called directly but used in DeferredPipeline::geometry_pass.
