One point in a contact manifold.

Fields

anchor_a: Vec3

Contact anchor on shape A in local contact coordinates.

anchor_b: Vec3

Contact anchor on shape B in local contact coordinates.

separation: f32

Current separation at the contact point.

base_separation: f32

Separation before solver updates.

normal_impulse: f32

Normal impulse applied at this point during the current solve.

total_normal_impulse: f32

Accumulated normal impulse for this contact point.

normal_velocity: f32

Relative normal velocity at the contact point.

feature_id: u32

Feature id used by Box3D to track contact persistence.

triangle_index: i32

Triangle index for mesh or height-field contacts, or Box3D’s sentinel value.

persisted: bool

Whether this contact point persisted from the previous step.

Implementations

impl ManifoldPoint

pub const fn from_raw(raw: b3ManifoldPoint) -> Self

Converts a raw Box3D manifold point into the Rust value type.

Trait Implementations

impl Clone for ManifoldPoint

fn clone(&self) -> ManifoldPoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ManifoldPoint

impl Debug for ManifoldPoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ManifoldPoint

fn default() -> ManifoldPoint

Returns the “default value” for a type.

impl PartialEq for ManifoldPoint

fn eq(&self, other: &ManifoldPoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
