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

[legend]

Detailed Description

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

Maps point positions to distances (in distance unit).

Template Parameters

TIn	parent point positions
TOut	corresponds to a scalar value: distance between point pairs, minus a rest distance. 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)

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

Reimplemented from sofa::core::BaseMapping.
