Detailed Description

This class represents a node in the Oriented Bounding Box Tree for a TriangleMesh.

Each node has an OrientedBoundingBox that fully encloses all triangles contained within it or its children. This is a binary tree: each non-leaf node has two children. Triangles are stored only in the leaf nodes.

Member Function Documentation

getBounds()

const OrientedBoundingBox& SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::getBounds

(

)

const

Get the OrientedBoundingBox which encloses all triangles in this node or its children.

isLeafNode()

bool SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::isLeafNode

(

)

const

Get whether this is a leaf node.

getFirstChildNode()

const OBBTreeNode SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::getFirstChildNode

(

)

const

Get the first child node.

Calling this on a leaf node will produce an exception.

getSecondChildNode()

const OBBTreeNode SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::getSecondChildNode

(

)

const

Get the second child node.

Calling this on a leaf node will produce an exception.

getTriangles()

const Array_<int>& SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::getTriangles

(

)

const

Get the indices of all triangles contained in this node.

Calling this on a non-leaf node will produce an exception.

getNumTriangles()

int SimTK::ContactGeometry::TriangleMesh::OBBTreeNode::getNumTriangles

(

)

const

Get the number of triangles inside this node.

If this is not a leaf node, this is the total number of triangles contained by all children of this node.
