class mrpt::opengl::CSetOfLines
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.

Construction
CSetOfLines()
Constructor.
CSetOfLines(const std::vector<mrpt::math::TSegment3D>& sgms, bool antiAliasing = true)
Constructor with a initial set of lines.
Methods
virtual void render(const RenderContext& rc) const
Implements the rendering of 3D objects in each class derived from CRenderizable.
This can be called more than once (one per required shader program) if the object registered several shaders.
See also:
virtual void renderUpdateBuffers() const
Called whenever m_outdatedBuffers is true: used to re-generate OpenGL vertex buffers, etc.
before they are sent for rendering in render()
virtual void freeOpenGLResources()
Free opengl buffers.
virtual shader_list_t requiredShaders() const
Returns the ID of the OpenGL shader program required to render this class.
See also:
virtual void onUpdateBuffers_Wireframe()
Must be implemented in derived classes to update the geometric entities to be drawn in “m_*_buffer” fields.
virtual void onUpdateBuffers_Points()
Must be implemented in derived classes to update the geometric entities to be drawn in “m_*_buffer” fields.
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 getLineCount() const
Returns the total count of lines in this set.
size_t size() const
Returns the total count of lines in this set.
bool empty() const
Returns true if there are no line segments.
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.
