Struct ParticleCollider 

pub struct ParticleCollider {
    pub plane_point: [f32; 3],
    pub plane_normal: [f32; 3],
    pub restitution: f32,
    pub friction: f32,
}

Particle-plane collision with restitution coefficient.

The plane is defined by a point and a normal (pointing into the “safe” side).

Fields

plane_point: [f32; 3]

A point on the plane.

plane_normal: [f32; 3]

Outward unit normal of the plane.

restitution: f32

Coefficient of restitution [0, 1]. 0 = inelastic, 1 = elastic.

friction: f32

Friction coefficient applied to tangential velocity on collision.

Implementations

impl ParticleCollider

pub fn floor(y: f32, restitution: f32) -> Self

Create a horizontal floor at height y with given restitution.

pub fn new( plane_point: [f32; 3], plane_normal: [f32; 3], restitution: f32, ) -> Self

Create a collider for a general plane.

pub fn resolve(&self, particle: &mut GpuParticle)

Resolve collision for one particle (modifies position and velocity).

pub fn resolve_all(&self, particles: &mut [GpuParticle])

Resolve collisions for all alive particles.
