Struct InterpolationState

Source

pub struct InterpolationState {
    pub prev: WorldSnapshot,
    pub current: WorldSnapshot,
}

Expand description

Interpolation state manager

Stores two snapshots (previous and current) and provides alpha-blended positions/rotations for rendering.

Fields§

§prev: WorldSnapshot

Previous physics state

§current: WorldSnapshot

Current physics state

Implementations§

Source §

impl InterpolationState

Source

pub const fn new(prev: WorldSnapshot, current: WorldSnapshot) -> Self

Create from two snapshots

Source

pub const fn empty() -> Self

Create empty

Source

pub fn push(&mut self, new_state: WorldSnapshot)

Push new physics state (current becomes prev)

Source

pub fn capture_and_push(&mut self, world: &PhysicsWorld)

Capture and push from physics world

Source

pub fn interpolate_position(&self, body_idx: usize, alpha: Fix128) -> Vec3Fix

Get interpolated position for a body

alpha is in [0, 1]: 0 = previous state, 1 = current state

Source

pub fn interpolate_rotation(&self, body_idx: usize, alpha: Fix128) -> QuatFix

Get interpolated rotation for a body (SLERP)

Source

pub fn interpolate(&self, body_idx: usize, alpha: Fix128) -> (Vec3Fix, QuatFix)

Get both interpolated position and rotation

Source

pub fn interpolate_all(&self, alpha: Fix128) -> Vec<(Vec3Fix, QuatFix)>

Get all interpolated transforms

Source

pub fn body_count(&self) -> usize

Number of bodies available for interpolation
