Fields§

§world_point: S::Point§anchor_a: S::Vector

Witness in A’s local frame.

§anchor_b: S::Vector

Witness in B’s local frame.

§normal: S::Vector

Unit, from A toward B.

§penetration: f32§normal_impulse: f32§tangent_dir: S::Vector

Valid within one step only: the slide direction can flip.

§tangent_impulse: f32

Cleared before each step; stored as a magnitude.

§velocity_bias: f32

Snapshot before the warm-start, constant across the PGS iterations.
