Member Function Documentation

virtual Real Klampt::VelocityObjective::Delta ( PlannerObjectiveBase priorGoal)

Subclasses: a similarity metric in for the amount of change between this objective and a prior goal. Results >= 0.

Reimplemented from Klampt::PlannerObjectiveBase.

virtual Real Klampt::VelocityObjective::PathCost ( const ParabolicRamp::DynamicPath path,
Real  tstart = 0 

Optional: return the cost of a candidate path starting at time tstart. This should be equal to the sum of the increment costs + the terminal cost

Reimplemented from Klampt::PlannerObjectiveBase.

References Klampt::PlannerObjectiveBase::Delta(), and ParabolicRamp::DynamicPath::ramps.

virtual Real Klampt::VelocityObjective::TerminalCost ( Real  tend,
const Vector &  qend,
const Vector &  dqend 

Subclasses: return the cost of a terminal state (qend,dqend) reached at time tend

Reimplemented from Klampt::PlannerObjectiveBase.
