Exploiting Degrees of Freedom Analysis for Interactive Constraint-based Design

  title={Exploiting Degrees of Freedom Analysis for Interactive Constraint-based Design},
  author={Terrence Fernando},
This paper presents an interactive constraint solver which exploits the degrees of freedom (DOFs) of under-constrained models to satisfy constraints and to support direct manipulation. The evolving constraints are maintained in a directed graph referred to as the Relationship Graph. A DOF technique referred to as allowable motion has been integrated with graph based algorithms to enable the constraint satisfaction, incrementally. Four basic constraint satisfaction methods (basic allowable… CONTINUE READING
