Constructor & Destructor Documentation

◆ ccPolyline() [1/2]

ccPolyline::ccPolyline ( GenericIndexedCloudPersist *  associatedCloud,
unsigned  uniqueID = ccUniqueIDGenerator::InvalidUniqueID 
)
explicit

Default constructor.

Parameters
associatedCloudthe associated point cloud (i.e. the vertices)
uniqueIDunique ID (handle with care)

◆ ccPolyline() [2/2]

ccPolyline::ccPolyline ( const ccPolyline poly)

Copy constructor.

Parameters
polypolyline to copy/clone

Member Function Documentation

◆ applyGLTransformation()

void ccPolyline::applyGLTransformation ( const ccGLMatrix trans)
overridevirtual

Applies a GL transformation to the entity.

this = rotMat*(this-rotCenter)+(rotCenter+trans)

Parameters
transa ccGLMatrix structure

Reimplemented from ccHObject.

◆ createNewPolylinesFromSelection()

bool ccPolyline::createNewPolylinesFromSelection ( std::vector< ccPolyline * > &  output)

Creates a polyline mesh with the selected vertices only.

This method is called after a graphical segmentation. It creates one or several new polylines with the segments having their two vertices tagged as "visible" (see ccGenericPointCloud::visibilityArray).

◆ drawBB()

virtual void ccPolyline::drawBB ( CC_DRAW_CONTEXT context,
const ccColor::Rgb col 
)
inlineoverridevirtual

Draws the entity (and its children) bounding-box.

Reimplemented from ccHObject.

◆ drawMeOnly()

void ccPolyline::drawMeOnly ( CC_DRAW_CONTEXT context)
overrideprotectedvirtual

Draws the entity only (not its children)

Reimplemented from ccHObject.

◆ fromFile_MeOnly()

bool ccPolyline::fromFile_MeOnly ( QFile &  in,
short  dataVersion,
int  flags,
LoadedIDMap oldToNewIDMap 
)
overrideprotectedvirtual

Loads own object data.

Called by 'fromFile' (recursive scheme) To be overloaded (but still called;) by subclass.

Parameters
ininput file
dataVersionfile version
flagsdeserialization flags (see ccSerializableObject::DeserializationFlags)
oldToNewIDMapmap to link old IDs with new IDs

Reimplemented from ccHObject.

◆ getClassID()

CC_CLASS_ENUM ccPolyline::getClassID ( ) const
inlineoverridevirtual

Returns class ID.

Reimplemented from ccHObject.

◆ getColor()

const ccColor::Rgb & ccPolyline::getColor ( ) const
inline

Returns the polyline color.

Returns
a pointer to the polyline RGB color

◆ getGlobalScale()

double ccPolyline::getGlobalScale ( ) const
overridevirtual

Returns the scale applied to original coordinates.

Reimplemented from ccShiftedObject.

◆ getGlobalShift()

const CCVector3d & ccPolyline::getGlobalShift ( ) const
overridevirtual

Returns the shift applied to original coordinates.

See ccGenericPointCloud::setOriginalShift

Reimplemented from ccShiftedObject.

◆ getOwnBB()

ccBBox ccPolyline::getOwnBB ( bool  withGLFeatures = false)
overridevirtual

Returns the entity's own bounding-box (with local/shifted coordinates)

Children bounding-boxes are ignored.

Parameters
withGLFeatureswhether to take into account display-only elements (if any)
Returns
bounding-box

Reimplemented from ccHObject.

◆ getUniqueIDForDisplay()

unsigned ccPolyline::getUniqueIDForDisplay ( ) const
overridevirtual

Returns object unique ID used for display.

Reimplemented from ccHObject.

◆ getWidth()

PointCoordinateType ccPolyline::getWidth ( ) const
inline

Returns the width of the line.

Returns
the width of the line in pixels

◆ hasColors()

bool ccPolyline::hasColors ( ) const
overridevirtual

Returns whether colors are enabled or not.

Reimplemented from ccDrawableObject.

◆ initWith()

bool ccPolyline::initWith ( ccPointCloud *&  vertices,
const ccPolyline poly 
)

Initializes the polyline with a given set of vertices and the parameters of another polyline.

Warning
Even the 'closed' state is copied as is!
Parameters
verticesset of vertices (can be null, in which case the polyline vertices will be cloned)
polypolyline
Returns
success

◆ isSerializable()

bool ccPolyline::isSerializable ( ) const
inlineoverridevirtual

Returns whether object is serializable of not.

Reimplemented from ccHObject.

◆ MetaKeyConstAltitude()

static QString ccPolyline::MetaKeyConstAltitude ( )
inlinestatic

Meta data key: contour plot constant altitude (for contour plots, etc.)

Expected value: altitude as double

◆ MetaKeyPrefixCenter()

static QString ccPolyline::MetaKeyPrefixCenter ( )
inlinestatic

Meta data key (prefix): intersection point between profile and its generatrix.

Expected value: 3D vector

Warning
must be followed by '.x', '.y' or '.z'

◆ MetaKeyPrefixDirection()

static QString ccPolyline::MetaKeyPrefixDirection ( )
inlinestatic

Meta data key (prefix): generatrix orientation at the point of intersection with the profile.

Expected value: 3D vector

Warning
must be followed by '.x', '.y' or '.z'

◆ MetaKeyUpDir()

static QString ccPolyline::MetaKeyUpDir ( )
inlinestatic

Meta data key: vertical direction (for 2D polylines, contour plots, etc.)

Expected value: 0(=X), 1(=Y) or 2(=Z) as int

◆ set2DMode()

void ccPolyline::set2DMode ( bool  state)

Defines if the polyline is considered as 2D or 3D.

Parameters
stateif true, the polyline is 2D

◆ setColor()

void ccPolyline::setColor ( const ccColor::Rgb col)
inline

Sets the polyline color.

Parameters
colRGB color

◆ setForeground()

void ccPolyline::setForeground ( bool  state)

Defines if the polyline is drawn in background or foreground.

Parameters
stateif true, the polyline is drawn in foreground

Such a shift can typically be applied at loading time. Original coordinates are equal to '(P/scale - shift)'

Reimplemented from ccShiftedObject.

Sets the width of the line.

Parameters
widththe desired width
