Function Documentation

int32 b2ClipSegmentToLine ( b2ClipVertex  vOut[2],
const b2ClipVertex  vIn[2],
const b2Vec2 normal,
float32  offset 
)

Clipping for contact manifolds.

void b2GetPointStates ( b2PointState  state1[b2_maxManifoldPoints],
b2PointState  state2[b2_maxManifoldPoints],
const b2Manifold manifold1,
const b2Manifold manifold2 
)

Compute the point states given two manifolds. The states pertain to the transition from manifold1 to manifold2. So state1 is either persist or remove while state2 is either add or persist.

bool b2TestOverlap ( const b2Shape shapeA,
const b2Shape shapeB,
const b2Transform xfA,
const b2Transform xfB 
)

Determine if two generic shapes overlap.
