std::pair< core::CollisionElementIterator, core::CollisionElementIterator > sofa::component::collision::CubeModel::getExternalChildren ( int ) const [virtual]

Return the list (as a pair of iterators) of external children of an element.

External children are child elements of a different type than their parent (often corresponding to the final elements).

Default to empty (i.e. two identical iterators)

Reimplemented from sofa::core::CollisionModel.

std::pair< core::CollisionElementIterator, core::CollisionElementIterator > sofa::component::collision::CubeModel::getInternalChildren ( int ) const [virtual]

Return the list (as a pair of iterators) of internal children of an element.

Internal children are child elements of the same type as their parent (often corresponding to non-final elements). This distinction is used to optimize the intersection tests inside the hierarchy, as internal children can be processed without dynamically retrieving a new intersection method.

Default to empty (i.e. two identical iterators)

bool sofa::component::collision::CubeModel::isLeaf ( int ) const [virtual]

Checks if the element(index) is a leaf and a primitive of the collision model.

Default to true since triangle model, line model, etc. does not have this method implemented and they are themselves (normally) leaves and primitives

void sofa::component::collision::CubeModel::resize ( int s ) [virtual]
