sofa::component::mapping::DistanceMapping< TIn, TOut > Class Template Reference

#include <DistanceMapping.h>

Inheritance diagram for sofa::component::mapping::DistanceMapping< TIn, TOut >:

Detailed Description

template<class TIn, class TOut>
class sofa::component::mapping::DistanceMapping< TIn, TOut >

Maps point positions to distances (in distance unit). Type TOut corresponds to a scalar value. The pairs are given in an EdgeSetTopologyContainer in the same node. If the rest lengths are not defined, they are set using the initial values. If computeDistance is set to true, the rest lengths are set to 0.

(Changed class name on Feb. 4, 2014, previous name was ExtensionMapping)

In: parent point positions

Out: distance between point pairs, minus a rest distance.

Returns pointers to Jacobian matrices associated with parent states, consistently with getFrom(). Most mappings have only one parent, however Multimappings have several parents. For efficiency concerns, please return pointers to defaulttype::EigenBaseSparseMatrix

const defaulttype::BaseMatrix * sofa::component::mapping::DistanceMapping< TIn, TOut >::getK ( )
overridevirtual

Returns a pointer to the geometric stiffness matrix. This is the equivalent of applyDJT, for matrix assembly instead of matrix-vector product. This matrix is associated with the parent DOFs. It is a square matrix with a size of the total number of parent DOFs. For efficiency concerns, please return a pointer to a defaulttype::EigenBaseSparseMatrix

Initialization method called at graph creation and modification, during top-down traversal.

void sofa::component::mapping::DistanceMapping< TIn, TOut >::updateForceMask ( )
overridevirtual

Useful when the mapping is applied only on a subset of parent dofs. It is automatically called by applyJT.

That way, we can optimize Jacobian sparsity. Every Dofs are inserted by default. The mappings using only a subset of dofs should only insert these dofs in the mask.

Implements sofa::core::BaseMapping.

Compute the geometric stiffness matrix based on given child forces K = dJ^T * outForce Default implementation does nothing, corresponding to a linear mapping.
