class mrpt::viz::CSetOfLines
Python API: mrpt.viz.CSetOfLines
Overview
A set of independent lines (or segments), one line with its own start and end positions (X,Y,Z).
Optionally, the vertices can be also shown as dots.

Typedefs
typedef std::shared_ptr<mrpt::viz ::CSetOfLines> Ptr
A type for the associated smart pointer.
Construction
CSetOfLines()
Constructor.
CSetOfLines(const std::vector<mrpt::math::TSegment3D>& sgms, bool antiAliasing = true)
Constructor with a initial set of lines.
Methods
virtual const mrpt::rtti::TRuntimeClassId* GetRuntimeClass() const
Returns information about the class of an object in runtime.
virtual mrpt::rtti::CObject* clone() const
Returns a deep copy (clone) of the object, indepently of its class.
void clear()
Clear the list of segments.
void setVerticesPointSize(const float size_points)
Enable showing vertices as dots if size_points>0.
void appendLine(const mrpt::math::TSegment3D& sgm)
Appends a line to the set.
void appendLine( double x0, double y0, double z0, double x1, double y1, double z1 )
Appends a line to the set, given the coordinates of its bounds.
void appendLineStrip(float x, float y, float z)
Appends a line whose starting point is the end point of the last line (similar to OpenGL’s GL_LINE_STRIP)
Parameters:
std::exception |
If there is no previous segment |
template <class U> void appendLineStrip(const U& point)
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template <class T> void appendLines(const T& sgms)
Appends any iterable collection of lines to the set.
Note that this includes another CSetOfLines.
See also:
template <class T_it> void appendLines(const T_it& begin, const T_it& end)
Appends certain amount of lines, located between two iterators, into the set.
See also:
void resize(size_t nLines)
Resizes the set.
See also:
void reserve(size_t r)
Reserves an amount of lines to the set.
This method should be used when some known amount of lines is going to be inserted, so that only a memory allocation is needed.
See also:
template <class T, class U> void appendLine(T p0, U p1)
Inserts a line, given its bounds.
Works with any pair of objects with access to x, y and z members.
size_t size() const
Returns the total count of lines in this set.
bool empty() const
Returns true if there are no line segments.
virtual void updateBuffers() const
Called by the rendering system to update internal geometry buffers.
Derived classes should override this to populate their data buffers (triangles, points, lines) when the object geometry changes.
This is called automatically when hasToUpdateBuffers() returns true, which happens after notifyChange() was called.
The base implementation does nothing; derived classes should override.
Thread safety: implementations should lock the appropriate mutexes when writing to shared buffers.
void setLineByIndex(size_t index, const mrpt::math::TSegment3D& segm)
Sets a specific line in the set, given its index.
See also:
void setLineByIndex( size_t index, double x0, double y0, double z0, double x1, double y1, double z1 )
Sets a specific line in the set, given its index.
See also:
void getLineByIndex( size_t index, double& x0, double& y0, double& z0, double& x1, double& y1, double& z1 ) const
Gets a specific line in the set, given its index.
See also:
const_iterator begin() const
Beginning const iterator.
See also:
const_iterator end() const
Ending const iterator.
See also:
const_reverse_iterator rbegin() const
Beginning const reverse iterator (actually, accesses the end of the set).
See also:
const_reverse_iterator rend() const
Ending const reverse iterator (actually, refers to the starting point of the set).
See also:
virtual mrpt::math::TBoundingBoxf internalBoundingBoxLocal() const
Evaluates the bounding box of this object (including possible children) in the coordinate frame of the object parent.
