virtualdefault

virtual nav_2d_msgs::Path2D dlux_global_planner::Traceback::getPath	(	const PotentialGrid &	potential_grid,
		const geometry_msgs::Pose2D &	start,
		const geometry_msgs::Pose2D &	goal,
		double &	path_cost
	)

pure virtual

Create the path from start to goal.

Parameters

potential_grid[in]	potential grid
start[in]	start pose
goal[in]	goal pose
path_cost[out]	A number representing the cost of taking this path. Open to intepretation.

virtual void dlux_global_planner::Traceback::initialize	(	ros::NodeHandle &	private_nh,
		CostInterpreter::Ptr	cost_interpreter
	)

inlinevirtual

Initialize function.

Can be overridden to grab parameters

Parameters

private_nh	NodeHandle to read parameters from
cost_interpreter	CostInterpreter pointer

	)

inlineprotected

Helper function to convert a path in Grid coordinates to World coordinates.

Does not use nav_grid::gridToWorld because that takes integer inputs, whereas the input path can be located anywhere within the grid cell.
