Member Function Documentation

void sofa::component::collision::GridModel::computeBoundingTree ( int maxDepth = 0 ) [virtual]

Create or update the bounding volume hierarchy.

Implements sofa::core::CollisionModel.

Definition at line 263 of file GridModel.cpp.

void sofa::component::collision::GridModel::draw ( ) [virtual]

Render the whole collision model.

Reimplemented from sofa::core::CollisionModel.

Definition at line 172 of file GridModel.cpp.

void sofa::component::collision::GridModel::draw ( int ) [virtual]

Render an collision element.

Reimplemented from sofa::core::CollisionModel.

Definition at line 135 of file GridModel.cpp.

std::pair< core::CollisionElementIterator, core::CollisionElementIterator > sofa::component::collision::GridModel::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.

Definition at line 213 of file GridModel.cpp.

std::pair< core::CollisionElementIterator, core::CollisionElementIterator > sofa::component::collision::GridModel::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)

Reimplemented from sofa::core::CollisionModel.

Definition at line 208 of file GridModel.cpp.

bool sofa::component::collision::GridModel::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

Reimplemented from sofa::core::CollisionModel.

Definition at line 230 of file GridModel.cpp.

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

Set the number of elements.

Reimplemented from sofa::core::CollisionModel.

Definition at line 53 of file GridModel.cpp.
