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). 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.
