Detailed Description

template<class TDataTypes>
class sofa::core::State< TDataTypes >

Component storing position and velocity vectors.

This class define the interface of components used as source and destination of regular (non mechanical) mapping. It is then specialized as MechanicalState (storing other mechanical data) or MappedModel (if no mechanical data is used, such as for VisualModel).

The given DataTypes class should define the following internal types:

• Real 

  : scalar values (float or double).

• Coord 

  : position values.

• Deriv 

  : derivative values (velocity).

• VecReal 

  : container of scalar values with the same API as sofa::type::vector.

• VecCoord 

  : container of Coord values with the same API as sofa::type::vector.

• VecDeriv 

  : container of Deriv values with the same API as sofa::type::vector.

• MatrixDeriv 

  : vector of Jacobians (sparse constraint matrices).
