Computes natural coordinates at rest, along with dependent nodes and the shape
function evaluated at the given point

|
BVTree |
getBVTree()
Return BV tree for those who know what to do with it
|
BVTree |
getElementBVTree()
The element bv tree bounds integration points contained by the element, which may be
slightly smaller than the true element bounds
|
BVTree |
getNodeBVTree()
Gets a BV tree that surrounds nodes (both false and true positions)
Note: does not surround influence regions, since these may be quite deformed
if not at rest, only bounds the nodes themselves
|
BVTree |
getRestNodeBVTree()
BV Tree that bounds the nodes at rest, and their spherical influence regions.

should be made to connect the returned attachment to the hierarchy;
the latter, if desired, is the responsibility of the caller.
In some cases, it may not be possible to attach the point at its present location. In that case, the method will create an attachment to the nearest feasible location.
