RealVectorRandomLinearProjectionEvaluator (const StateSpace *space, unsigned int dim) | |

Initialize a linear projection evaluator for state space space. The used projection matrix is sampled at random to produce a space of dimension dim and the cell sizes are automatically inferred through sampling. | |

RealVectorRandomLinearProjectionEvaluator (const StateSpacePtr &space, unsigned int dim) | |

Initialize a linear projection evaluator for state space space. The used projection matrix is sampled at random to produce a space of dimension dim and the cell sizes are automatically inferred through sampling. | |

RealVectorLinearProjectionEvaluator (const StateSpace *space, const std::vector< double > &cellSizes, const ProjectionMatrix::Matrix &projection) | |

Initialize a linear projection evaluator for state space space. The used projection matrix is projection and the cell sizes are cellSizes. | |

RealVectorLinearProjectionEvaluator (const StateSpacePtr &space, const std::vector< double > &cellSizes, const ProjectionMatrix::Matrix &projection) | |

Initialize a linear projection evaluator for state space space. The used projection matrix is projection and the cell sizes are cellSizes. | |

RealVectorLinearProjectionEvaluator (const StateSpace *space, const ProjectionMatrix::Matrix &projection) | |

Initialize a linear projection evaluator for state space space. The used projection matrix is projection and the cell sizes are automatically inferred through sampling. | |

unsigned int | getDimension () const override |

Return the dimension of the projection defined by this evaluator. | |

void | project (const State *state, Eigen::Ref< Eigen::VectorXd > projection) const override |

Compute the projection as an array of double values. | |

Public Member Functions inherited from ompl::base::ProjectionEvaluator | |

ProjectionEvaluator (const ProjectionEvaluator &)=delete | |

ProjectionEvaluator & | operator= (const ProjectionEvaluator &)=delete |

ProjectionEvaluator (const StateSpace *space) | |

Construct a projection evaluator for a specific state space. | |

ProjectionEvaluator (const StateSpacePtr &space) | |

Construct a projection evaluator for a specific state space. | |

virtual void | setCellSizes (const std::vector< double > &cellSizes) |

Define the size (in each dimension) of a grid cell. The number of sizes set here must be the same as the dimension of the projection computed by the projection evaluator. After a call to this function, setup() will not call defaultCellSizes() or inferCellSizes() any more. | |

void | setCellSizes (unsigned int dim, double cellSize) |

Set the cell sizes to cellSize for a particular dimension dim. This function simply calls getCellSizes(), modifies the desired dimension and then calls setCellSizes(). This is done intentionally to enforce a call to setCellSizes(). | |

void | mulCellSizes (double factor) |

Multiply the cell sizes in each dimension by a specified factor factor. This function does nothing if cell sizes have not been set. If cell sizes have been set (irrespective of source; e.g., user, default or inferred), this function will then call setCellSizes(), so the source of the cell sizes will be considered to be the user. | |

bool | userConfigured () const |

Return true if any user configuration has been done to this projection evaluator (setCellSizes() was called) | |

const std::vector< double > & | getCellSizes () const |

Get the size (each dimension) of a grid cell | |

double | getCellSizes (unsigned int dim) const |

Get the size of a particular dimension of a grid cell | |

void | checkCellSizes () const |

Check if cell dimensions match projection dimension. | |

void | inferCellSizes () |

Sample the state space and decide on default cell sizes. This function is called by setup() if no cell dsizes have been set and defaultCellSizes() does not fill the cell sizes either. | |

virtual void | defaultCellSizes () |

Set the default cell dimensions for this projection. The default implementation of this function is empty. setup() calls this function if no cell dimensions have been previously set. | |

void | checkBounds () const |

Check if the projection dimension matched the dimension of the bounds. | |

bool | hasBounds () const |

Check if bounds were specified for this projection. | |

void | setBounds (const RealVectorBounds &bounds) |

Set bounds on the projection. The PDST planner needs to known the bounds on the projection. Default bounds are automatically computed by inferCellSizes(). | |

const RealVectorBounds & | getBounds () const |

Get the bounds computed/set for this projection. | |

void | inferBounds () |

Compute an approximation of the bounds for this projection space. getBounds() will then report the computed bounds. | |

virtual void | setup () |

Perform configuration steps, if needed. | |

void | computeCoordinates (const Eigen::Ref< Eigen::VectorXd > &projection, Eigen::Ref< Eigen::VectorXi > coord) const |

Compute integer coordinates for a projection. | |

void | computeCoordinates (const State *state, Eigen::Ref< Eigen::VectorXi > coord) const |

Compute integer coordinates for a state. | |

ParamSet & | params () |

Get the parameters for this projection. | |

const ParamSet & | params () const |

Get the parameters for this projection. | |

virtual void | printSettings (std::ostream &out=std::cout) const |

Print settings about this projection. | |

virtual void | printProjection (const Eigen::Ref< Eigen::VectorXd > &projection, std::ostream &out=std::cout) const |

Print a euclidean projection. | |

RealVectorBounds | estimatedBounds_ |

An approximate bounding box for projected state values; This is the cached result of estimateBounds() which may later be copied to bounds_ if bounds are needed but were not specified. | |

bool | defaultCellSizes_ |

Flag indicating whether cell sizes have been set by the user, or whether they were inferred automatically. This flag becomes false if setCellSizes() is called. | |

Flag indicating whether projection cell sizes were automatically inferred. | |
