## Public Member Functions | |

TangentBundleStateSpace (const StateSpacePtr &ambientSpace, const ConstraintPtr &constraint) | |

void | sanityChecks () const override |

Do sanity checks, minus geodesic constraint satisfiability (as this is a lazy method). | |

bool | discreteGeodesic (const State *from, const State *to, bool interpolate=false, std::vector< State * > *geodesic=nullptr) const override |

Traverse the manifold from from toward to. Returns true if we reached to, and false if we stopped early for any reason, such as a collision or traveling too far. No collision checking is performed if interpolate is true. If geodesic is not nullptr, the sequence of intermediates is saved to it, including a copy of from, as well as the final state, which is a copy of to if we reached to. Caller is responsible for freeing states returned in geodesic. | |

State * | geodesicInterpolate (const std::vector< State * > &geodesic, double t) const override |

Like interpolate(...), but interpolates between intermediate states already supplied in stateList from a previous call to discreteGeodesic(..., geodesic). The from and to states are the first and last elements stateList. Returns a pointer to a state in geodesic. As TangentBundleStateSpace employs a lazy approach to manifold traversal, additional fix-up is required to generate a state that satisfies constraints. | |

bool | project (State *state) const |

Reproject a state onto the surface of the manifold. Returns true if projection was successful, and the new state is valid. | |

## Detailed Description

ConstrainedStateSpace encapsulating a planner-agnostic lazy atlas algorithm for planning on a constraint manifold.

- Short Description
- TangentBundleStateSpace implements a lazy atlas-based methodology for constrained sampling-based planning, where the underlying constraint manifold is locally parameterized by
*charts*(AtlasChart). The underlying constraint manifold can then be sampled and explored using the collection of these charts (an*atlas*). The difference between TangentBundleStateSpace and AtlasStateSpace is three-fold: TangentBundleStateSpace takes a lazy approach to evaluating the constraint function when traversing the manifold, TangentBundleStateSpace uses biased sampling for selected charts by default, and TangentBundleStateSpace does not use halfspace separation of charts.

- External Documentation
- This state space is inspired by the work on Tangent Bundle RRT.
