how to get tow collide objs contacts

[myagen]

hello my friends
I noticed that getting the contact points of two colliding objects was wrong，as bellow is my testing codes

fcl::CollisionResult<S> local_resul;

local_result.clear();
std::vector<Contact<S>> contacts;
contacts.clear();

detail::MeshCollisionTraversalNode<BV> node;
```
if (!detail::initialize(
node, m1, pose1, m2, pose2,
CollisionRequest<S>(num_max_contacts, true, num_max_contacts, true), local_result)) {
return -1;
}

           ` node.enable_statistics = true;`

           ` detail::collide(&node);`
          `  if (local_result.numContacts() > 0) {`
             `   /*local_result.getContacts(contacts);`
            `    std::sort(contacts.begin(), contacts.end());*/`
              `  local_result.clear();`

              `  CollisionRequest<S> request(num_max_contacts, true);`
             `   int num_contacts = collide(&m1, pose1, &m2, pose2, request, local_result);`
            `    local_result.getContacts(contacts);// `
}

local_result.getContacts(contacts);  is not right to get the contacts

could you tell us how to get these contact points by use the function getContacts

Thanks!
