Can't register Plane or Halfplane to DynamicAABBTreeCollisionManager

[lmontaut]

Hi @salihmarangoz,
Thanks for reporting this issue! The problem was due do uninitialized iterators, it should be fixed with #515.

Could you share a reproducible example please?

Did some tests:

• Spheres -> ok
• Inflated spheres -> ok
• Spheres + Inflated spheres -> ok
• Spheres + plane -> ok
• Inflated spheres + plane -> segmentation fault

Multiple inflated spheres are ok. But planes don't work together with inflated spheres. Perhaps is there a problem with using the copy constructor of Sphere?

#include <hpp/fcl/shape/geometric_shapes.h>
#include <hpp/fcl/collision.h>
#include <hpp/fcl/broadphase/broadphase.h>

using hpp::fcl::DynamicAABBTreeCollisionManager;
using hpp::fcl::Vec3f;
using hpp::fcl::CollisionObject;
using hpp::fcl::Sphere;
using hpp::fcl::Plane;


int main()
{
  DynamicAABBTreeCollisionManager collision_manager;

  std::vector<CollisionObject*> collision_objects;

  // auto o1 = new CollisionObject(hpp::fcl::make_shared<Sphere>(0.1));
  // o1->setTranslation(Vec3f(0.2, 0.1, 0.4));
  // o1->computeAABB();
  // collision_objects.push_back(o1);

  // auto o2 = new CollisionObject(hpp::fcl::make_shared<Sphere>(0.2));
  // o2->setTranslation(Vec3f(0.3, 0.2, 0.4));
  // o2->computeAABB();
  // collision_objects.push_back(o2);

  auto o3 = new CollisionObject(hpp::fcl::make_shared<Plane>(0.0, 0.0, 1.0, 0.0));
  o3->computeAABB();
  collision_objects.push_back(o3);

  auto o4 = new CollisionObject(hpp::fcl::make_shared<Sphere>(Sphere(0.05).inflated(0.05).first));
  o4->setTranslation(Vec3f(0.1, 0.3, 0.4));
  o4->computeAABB();
  collision_objects.push_back(o4);

  collision_manager.registerObjects(collision_objects);
  collision_manager.update();
}
