A manifold point is a contact point belonging to a contact manifold. Box3D uses speculative collision so some contact points may be separated. (b3ManifoldPoint)

Fields

anchor_a: Vec3

Location of the contact point relative to body A center of mass in world space.

anchor_b: Vec3

Location of the contact point relative to body B center of mass in world space.

separation: f32

Separation of the contact point; negative if penetrating.

base_separation: f32

Cached separation used for contact recycling.

normal_impulse: f32

Impulse along the manifold normal from the final sub-step.

total_normal_impulse: f32

Total normal impulse applied during sub-stepping.

normal_velocity: f32

Relative normal velocity pre-solve. Negative means approaching.

feature_id: u32

Uniquely identifies a contact point between two shapes.

triangle_index: i32

Triangle index if one of the shapes is a mesh or height field.

persisted: bool

Did this contact point exist in the previous step?
