Detailed Description

This is used to compute the current state of a contact manifold.

Member Function Documentation

void b2WorldManifold::Initialize ( const b2Manifold manifold,
const b2Transform xfA,
float32  radiusA,
const b2Transform xfB,
float32  radiusB 
)

Evaluate the manifold with supplied transforms. This assumes modest motion from the original state. This does not change the point count, impulses, etc. The radii must come from the shapes that generated the manifold.
