* \ingroup PkgAABB_tree
|
|
* Primitive type for a facet of a polyhedral surface.
|
|
* It wraps a handle to a facet of a polyhedron to a 3D triangle.
|
|
* The polyhedron from which the primitive is built should not be deleted
|
|
* while the AABB tree holding the primitive is in use.
|
|
*
|
|
* \cgalModels `AABBPrimitive` if `OneFaceGraphPerTree` is `CGAL::Tag_false`,
|
|
* and `AABBPrimitiveWithSharedData` if `OneFaceGraphPerTree` is `CGAL::Tag_true`.
|
|
*
|
|
*\tparam FaceGraph is a \cgal Polyhedron.
|
|
*\tparam OneFaceGraphPerTree must be set to `CGAL::Tag_true`.
|
|
* This parameter is useless for the moment and will be useful in an upcoming release of \cgal.
|
|
*\tparam cache_datum is either `CGAL::Tag_true` or `CGAL::Tag_false`. In the former case, the datum is stored
|
|
* in the primitive, while in the latter it is constructed on the fly to reduce the memory footprint.
|
|
* The default is `CGAL::Tag_false` (datum is not stored).
