class mrpt::maps::CSimplePointsMap
A cloud of points in 2D or 3D, which can be built from a sequence of laser scans.
This class only stores the coordinates (x,y,z) of each point.
See mrpt::maps::CPointsMap and derived classes for other point cloud classes.

Construction
CSimplePointsMap()
Default constructor.
Methods
virtual void reserve(size_t newLength)
Reserves memory for a given number of points: the size of the map does not change, it only reserves the memory.
This is useful for situations where it is approximately known the final size of the map. This method is more efficient than constantly increasing the size of the buffers. Refer to the STL C++ library’s “reserve” methods.
virtual void resize(size_t newLength)
Resizes all point buffers so they can hold the given number of points: newly created points are set to default values, and old contents are not changed.
See also:
reserve, setPoint, setPointFast, setSize
virtual void setSize(size_t newLength)
Resizes all point buffers so they can hold the given number of points, erasing all previous contents and leaving all points to default values.

reserve, setPoint, setPointFast, setSize
virtual void insertPointFast(float x, float y, float z = 0)
The virtual method for insertPoint() without calling mark_as_modified()
virtual void getPointAllFieldsFast(size_t index, std::vector<float>& point_data) const
Get all the data fields for one point as a vector: [X Y Z] Unlike getPointAllFields(), this method does not check for index out of bounds.
See also:
getPointAllFields, setPointAllFields, setPointAllFieldsFast
virtual void setPointAllFieldsFast( size_t index, const std::vector<float>& point_data )
Set all the data fields for one point as a vector: [X Y Z] Unlike setPointAllFields(), this method does not check for index out of bounds.

setPointAllFields, getPointAllFields, getPointAllFieldsFast
virtual void loadFromRangeScan( const mrpt::obs::CObservation2DRangeScan& rangeScan, const std::optional<const mrpt::poses::CPose3D>& robotPose = std::nullopt )
Transform the range scan into a set of cartessian coordinated points.
The options in “insertionOptions” are considered in this method. Only ranges marked as “valid=true” in the observation will be inserted
Each derived class may enrich points in different ways (color, weight, etc..), so please refer to the description of the specific implementation of mrpt::maps::CPointsMap you are using.
The actual generic implementation of this file lives in <src>/CPointsMap_crtp_common.h, but specific instantiations are generated at each derived class.
Parameters:
rangeScan |
The scan to be inserted into this map |
robotPose |
Default to (0,0,0|0deg,0deg,0deg). Changes the frame of reference for the point cloud (i.e. the vehicle/robot pose in world coordinates). |

CObservation2DRangeScan, CObservation3DRangeScan
virtual void loadFromRangeScan( const mrpt::obs::CObservation3DRangeScan& rangeScan, const std::optional<const mrpt::poses::CPose3D>& robotPose = std::nullopt )
Overload of loadFromRangeScan() for 3D range scans (for example, Kinect observations).

Parameters:
rangeScan |

robotPose |
Default to (0,0,0|0deg,0deg,0deg). Changes the frame of reference for the point cloud (i.e. the vehicle/robot pose in world coordinates). |

virtual const mrpt::maps::CSimplePointsMap* getAsSimplePointsMap() const
If the map is a simple points map or it’s a multi-metric map that contains EXACTLY one simple points map, return it.
Otherwise, return nullptr
