Detailed Description

Model instance to draw a 2D line with styleable segments.

Constructor & Destructor Documentation

makVrv::DtOsgOverlayDirectionLineModelInstance::DtOsgOverlayDirectionLineModelInstance ( DtDe & de )

CTOR.

virtual makVrv::DtOsgOverlayDirectionLineModelInstance::~DtOsgOverlayDirectionLineModelInstance ( )

virtual

DTOR.

Member Function Documentation

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setVisible ( bool )

virtual

Sets model shown/hidden.

Implements makVrv::DtModelInstance.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setModelSet ( int modelSet )

virtual

Sets the model set for the overlay.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::addPoint	(	const DtVector &	position,
		int	index = `-1`
	)

virtual

Each set of two points will represent a segment on the line, so, the origin to second point is the first segment, second to third point is the second segment, etc.

As points are added or removed, this could influence how the segment styles will be applied. A segment style will be associated with a particular segment and will not change its segment index based on points added or removed

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setPosition	(	int	index,
		const DtVector &	position
	)

virtual

Sets the position of the point at the specified location.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setStipplePattern ( unsigned int stipple )

virtual

Segment parameters for stippling.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setColor	(	float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set segment color.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setWidth ( float width )

virtual

Sets the width of the segment (in pixels)

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setEventsEnabled	(	bool	,
		unsigned long long	userData
	)

virtual

Eanble or disable picking and mouse-over events.

bool makVrv::DtOsgOverlayDirectionLineModelInstance::eventsEnabled ( ) const

Return whether events are enabled.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setPositionOffset ( const DtVector & )

virtual

Offsets vertices by given offset.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setDirection	(	int	index,
		const DtVector &	direction
	)

virtual

Sets the 3D direction of the vertex.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::setLength	(	int	index,
		float	length
	)

virtual

Sets the 2D (screen space) length/offset of the vertex in the direction set by setDirection.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::update ( )

virtual

Called when it's time to update the rendered object.

virtual bool makVrv::DtOsgOverlayDirectionLineModelInstance::realize ( DtModelDefinition & definition )

virtual

Attempt to realize a definition.

If the model instance can't realize the definition it should return false.

Reimplemented from makVrv::DtModelInstance.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::createLineIfNecessary ( )

protectedvirtual

Creates the line model.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::updateAttributes ( )

protectedvirtual

Updates the segment information.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::updateGeometry ( )

protectedvirtual

Updates the line's geometry.

virtual void makVrv::DtOsgOverlayDirectionLineModelInstance::set3DVertexPosition	(	unsigned int	index,
		double	x,
		double	y,
		double	z
	)

protectedvirtual

Sets a lines vertex's position.
