Detailed Description

Component computing projective constraints within a simulated body.

This class define the abstract API common to all projective constraints. A BaseConstraint computes constraints applied to one or more simulated body given its current position and velocity.

Constraints can be internal to a given body (attached to one MechanicalState, see the Constraint class), or link several bodies together (such as contacts, see the InteractionConstraint class).

pure virtual

◆ insertInNode()

bool sofa::core::behavior::BaseProjectiveConstraintSet::insertInNode ( objectmodel::BaseNode )

the component can insert itself directly in the right sequence in the Node so the Node does not have to test its type against all known types

Returns
true if the component was inserted

◆ projectMatrix()

virtual void sofa::core::behavior::BaseProjectiveConstraintSet::projectMatrix ( sofa::linearalgebra::BaseMatrix ,
unsigned   
)
inlinevirtual

Project the given matrix (Experimental API). Replace M with PMP, where P is the projection matrix corresponding to the projectResponse method. Contrary to applyConstraint(), the diagonal blocks of the result are not reset to the identity. Typically, M is the (generalized) mass matrix of the whole system, offset is the starting index of the local state in this global matrix, and P is the identity matrix with a block on the diagonal replaced by the projection matrix. If M is the matrix of the local state, then offset should be 0.
