Templated class which computes Group Marching Method (GMM). More...
#include <gmm.hpp>
Public Member Functions | |
| GMM (double dt=-1) | |
| GMM (const char *name, double dt=-1) | |
| void | setup () |
| Checks that the solver is ready to run. Sets the grid unclean. | |
| virtual void | computeInternal () |
| Actual method that implements GMM. | |
| virtual void | clear () |
| Clears the solver, it is not recommended to be used out of the destructor. | |
| virtual void | reset () |
| Clears temporal data, so it is ready to run again. | |
 Public Member Functions inherited from EikonalSolver< grid_t > | |
| EikonalSolver (const std::string &name) | |
| virtual double | solveEikonal (const int &idx) |
| Solves nD Eikonal equation for cell idx. If heuristics are activated, it will add the estimated travel time to goal with current velocity. More... | |
| Public Member Functions inherited from Solver< grid_t > | |
| Solver (const std::string &name) | |
| virtual void | setEnvironment (grid_t *g) |
| Sets and cleans the grid in which operations will be performed. | |
| virtual void | setInitialAndGoalPoints (const std::vector< unsigned int > &init_points, unsigned int goal_idx) |
| Sets the initial and goal points by the indices of the grid. | |
| virtual void | setInitialPoints (const std::vector< unsigned int > &init_points) |
| Sets the initial points by the indices of the grid. | |
| virtual void | setInitialAndGoalPoints (const std::array< unsigned int, grid_t::getNDims()> &init_coord, const std::array< unsigned int, grid_t::getNDims()> &goal_coord) |
| Sets the initial and goal points by the coordinates of the grid. | |
| virtual void | setInitialPoints (const std::array< unsigned int, grid_t::getNDims()> &init_coord) |
| Sets the initial point by the coordinates of the grid. | |
| void | compute () |
| Computes the distances map. Will call setup() if not done already. | |
| template<class T > | |
| T * | as () |
| Cast this instance to a desired type. | |
| template<class T > | |
| const T * | as () const |
| Cast this instance to a desired type. | |
| const std::string & | getName () const |
| Returns name of the solver. | |
| grid_t * | getGrid () const |
| Returns a pointer to the grid used. | |
| virtual double | getTime () const |
| virtual void | printRunInfo () const |
Private Attributes | |
| double | tm_ |
| Global bound that determines the group of cells of gamma that will be updated in each step. | |
| double | deltau_ |
| For each updating step, tm_ is increased by this value. | |
| std::list< unsigned int > | gamma_ |
| List wich stores the narrow band of each iteration. | |

std::chrono::time_point < std::chrono::steady_clock > | end_ |
| double | time_ |
| Time elapsed by the compute method. | |
It uses as a main container the nDGridMap class. The nDGridMap type T has to be an FMCell or something inherited from it.
The grid is assumed to be squared, that is Delta(x) = Delta(y) = leafsize_
