Expand description

Material properties for contact interactions.

Fields§

§stiffness: f64

Contact stiffness (N/m).

§damping: f64

Contact damping (N·s/m).

§friction: f64

Coefficient of friction (dimensionless).

§bounce: f64

Coefficient of restitution (0 = inelastic, 1 = elastic).

§soft_cfm: f64

Constraint force mixing (for numerical stability).

§soft_erp: f64

Error reduction parameter (for constraint drift correction).
