Struct SingleModifiedSdf 

pub struct SingleModifiedSdf<M: PhysicsModifier> {
    pub original: Box<dyn SdfField>,
    pub modifier: M,
    /* private fields */
}

Lightweight SDF wrapper for a single modifier (avoids Vec overhead).

Evaluates as a ModifiedSdf holding that one modifier: the distance is modifier.modify_distance(p, original(p)) while PhysicsModifier::is_active is true and original(p) otherwise, and Self::update advances the modifier whether or not it is active.

Fields

original: Box<dyn SdfField>

Original SDF

modifier: M

The modifier

Implementations

impl<M: PhysicsModifier> SingleModifiedSdf<M>

pub fn new(original: Box<dyn SdfField>, modifier: M) -> Self

Create wrapper with a single modifier

pub fn update(&mut self, dt: f32)

Update the modifier simulation

Trait Implementations

impl<M: PhysicsModifier> SdfField for SingleModifiedSdf<M>

fn distance(&self, x: f32, y: f32, z: f32) -> f32

Returns the signed distance from point to the nearest surface.

fn normal(&self, x: f32, y: f32, z: f32) -> (f32, f32, f32)

Returns the surface normal (normalized gradient) at the given point.

fn distance_and_normal(&self, x: f32, y: f32, z: f32) -> (f32, (f32, f32, f32))

Combined distance + normal query (default: two separate calls).

fn generation(&self) -> u64

A number that changes whenever the field changes shape (default: 0, a field that never changes).
