struct Manifold

Section titled “struct Manifold”
struct Manifold

What the narrow phase knows about one overlap: the axis it happened on, and how deep it is.

This is the value PHILOSOPHY's Collision section names, and having it be a value is most of the point: it is a measurement - an axis and a depth, from one query - rather than a classification.

normal

Section titled “normal”
mattmath::Vector2F normal = mattmath::Vector2F::ZERO;

Unit length, pointing from the first shape towards the second.

penetration

Section titled “penetration”
float penetration = 0.0f;

How far the two overlap along normal. Always greater than zero: a manifold only exists where there is an overlap, and shapes that merely touch do not overlap.

Section titled “Related types”

Named in the public declarations above: Vector2F.
