Struct ModifiedSdf 

pub struct ModifiedSdf { /* private fields */ }

SDF wrapper that applies a chain of physics modifiers.

Implements SdfField, so it can be used anywhere an SDF is expected.

Implementations

impl ModifiedSdf

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

Create a new modified SDF wrapping the original field

pub fn with_modifier(self, modifier: Box<dyn PhysicsModifier>) -> Self

Add a modifier to the chain

pub fn add_modifier(&mut self, modifier: Box<dyn PhysicsModifier>)

Add a modifier (mutable)

pub fn clear_modifiers(&mut self)

Remove all modifiers

pub fn modifier_count(&self) -> usize

Number of active modifiers

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

Update all modifier simulations

pub fn modifier_mut(&mut self, index: usize) -> Option<&mut dyn PhysicsModifier>

Get mutable access to a modifier by index

Trait Implementations

impl SdfField for ModifiedSdf

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).
