Detailed Description

A planner that perturbs the current configuration to get an improved path.

Member Function Documentation

virtual int Klampt::DynamicPerturbationPlanner::PlanFrom ( ParabolicRamp::DynamicPath path,
Real  cutoff 

DynamicMotionPlanner subclasses should override this. Plans from the start of 'path', and returns the result in 'path'. The planning duration should not exceed 'cutoff', if possible.

Must return Success if successful, Failure if planning fails.

Subroutines may maintain a timer, and stop and return Timeout planning time exceeds the cutoff. This is not strictly necessary; the caller should check whether the planning time exceeds the cutoff.

Reimplemented from Klampt::DynamicMotionPlannerBase.
