Enum FrictionModel 

pub enum FrictionModel {
    Simplified,
    Coulomb,
}

Friction models used for all contact constraints between two rigid-bodies.

This selection does not apply to multibodies that always rely on the FrictionModel::Coulomb.

Variants

Simplified

A simplified friction model significantly faster to solve than Self::Coulomb but less accurate.

Instead of solving one Coulomb friction constraint per contact in a contact manifold, this approximation only solves one Coulomb friction constraint per group of 4 contacts in a contact manifold, plus one “twist” constraint. The “twist” constraint is purely rotational and aims to eliminate angular movement in the manifold’s tangent plane.

Coulomb

The coulomb friction model.

This results in one Coulomb friction constraint per contact point.

Trait Implementations

impl Clone for FrictionModel

fn clone(&self) -> FrictionModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrictionModel

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

Formats the value using the given formatter.

impl Default for FrictionModel

fn default() -> FrictionModel

Returns the “default value” for a type.

impl PartialEq for FrictionModel

fn eq(&self, other: &FrictionModel) -> 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.

impl Copy for FrictionModel

impl Eq for FrictionModel

impl StructuralPartialEq for FrictionModel
