Fields

points: Vec<VerletPoint>

structural_constraints: Vec<DistanceConstraint>

Implementations

impl ClothStrip

pub fn new( width_points: usize, height_points: usize, spacing: f32, anchor_pos: Vec3, ) -> Self

Create a cloth grid of width_points x height_points, anchored at anchor_pos (top-left corner). Points are spaced spacing apart.

pub fn step(&mut self, dt: f32, iterations: usize)

Advance simulation by dt with iterations constraint relaxation passes.

pub fn apply_force(&mut self, force: Vec3)

Apply a uniform force to all unpinned points.

pub fn apply_wind(&mut self, direction: Vec3, strength: f32, turbulence: f32)

Apply wind with directional bias plus turbulence noise.

pub fn pin_point(&mut self, index: usize)

Pin a point so it does not move.

pub fn unpin_point(&mut self, index: usize)

Unpin a point so it can move freely.

pub fn tear_at(&mut self, index: usize)

Tear the cloth at a point by deactivating all constraints referencing it.

pub fn get_render_data(&self) -> Vec<[f32; 3]>

Return all point positions as [f32; 3] arrays for rendering.

pub fn set_point_position(&mut self, index: usize, pos: Vec3)

Move a pinned point to a new position (useful for anchoring to entities).

pub fn is_expired(&self) -> bool

Check if this cloth has expired (lifetime > 0 and age exceeded).

pub fn active_constraint_count(&self) -> usize

Number of active structural constraints.
