Draws the entity only (not its children)

Reimplemented from ccHObject.

inline

Returns the width of the line.

Returns: the width of the line in pixels

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

vertices	set of vertices (can be null, in which case the polyline vertices will be cloned)
poly	polyline

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

state if true, the polyline is 2D

◆ setColor()

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

inline

Sets the polyline color.

Parameters

col RGB color

◆ setForeground()

void ccPolyline::setForeground ( bool state )

Defines if the polyline is drawn in background or foreground.

Parameters

state if true, the polyline is drawn in foreground

Reimplemented from ccShiftedObject.

◆ setGlobalShift()

void ccPolyline::setGlobalShift ( const CCVector3d & shift )

Sets shift applied to original coordinates (information storage only)

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

Reimplemented from ccShiftedObject.
