Struct DeformationStack 

pub struct DeformationStack {
    pub deformations: Vec<Deformation>,
    pub time: f32,
    pub master_weight: f32,
}

A stack of deformations applied sequentially to a mesh.

Fields

deformations: Vec<Deformation>

time: f32

master_weight: f32

Master weight applied to all deformations.

Implementations

impl DeformationStack

pub fn new() -> Self

Create a new empty deformation stack.

pub fn push(&mut self, deformation: Deformation)

Add a deformation to the stack.

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

Remove a deformation by index.

pub fn clear(&mut self)

Clear all deformations.

pub fn set_time(&mut self, time: f32)

Set the time for all deformations.

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

Advance time by dt.

pub fn apply(&self, position: Vec3, normal: Vec3) -> Vec3

Apply all deformations to a vertex.

pub fn apply_to_positions(&self, positions: &mut [Vec3], normals: &[Vec3])

Apply all deformations to a mesh (modifying positions in place).

pub fn compute_displaced( &self, positions: &[Vec3], normals: &[Vec3], ) -> Vec<Vec3>

Apply all deformations and return displaced positions (non-mutating).

pub fn active_count(&self) -> usize

Get the number of active deformations.

pub fn set_weight(&mut self, index: usize, weight: f32)

Set the weight of a deformation by index.

pub fn set_active(&mut self, index: usize, active: bool)

Enable/disable a deformation by index.

Trait Implementations

impl Default for DeformationStack

fn default() -> Self

Returns the “default value” for a type.
