Member Function Documentation

void makVrv::DtLineSegment::setGroup ( float group )

virtual

Set the group of the line segment.

Setting the group to zero causes the line to be hidden. Setting the group to negative numbers causes the line to be drawn relative to North. 1

Implements makVrv::DtLineSegmentInterface.

int makVrv::DtLineSegment::group ( ) const

virtual

Get the group.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::set2DPositions	(	float	x1,
		float	y1,
		float	x2,
		float	y2
	)

virtual

Set the vertex positions.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::set2DPosition	(	unsigned int	index0or1,
		float	x,
		float	y
	)

virtual

Set the first vertex position.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::get2DPosition	(	unsigned int	index0or1,
		float &	x,
		float &	y
	)		const

virtual

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::setColors	(	float	r1,
		float	g1,
		float	b1,
		float	a1,
		float	r2,
		float	g2,
		float	b2,
		float	a2
	)

virtual

Set the vertex colors.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::set3DPosition	(	int	index0or1,
		float	dx,
		float	dy,
		float	z,
		float	w
	)

virtual

Set the 3D location of the line.

This will set the 3D location for each end of the line.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::get3DPosition	(	int	index0or1,
		float &	dx,
		float &	dy,
		float &	z,
		float &	w
	)		const

virtual

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtLineSegment::set3DDirection	(	unsigned int	index0or1,
		float	x,
		float	y,
		float	z
	)

virtual

Set the normalized direction of the line in world space.

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtLineSegment::get3DDirection	(	unsigned int	index0or1,
		float &	x,
		float &	y,
		float &	z
	)		const

virtual

Get the normalized direction of the vertex.

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtLineSegment::setDirection2DLength	(	unsigned int	index0or1,
		float	length
	)

virtual

Set the length of the line in 2D space.

Implements makVrv::DtLineSegmentInterface.

virtual float makVrv::DtLineSegment::direction2DLength ( unsigned int index0or1 ) const

virtual

Get the length of the line in 2D space.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::setColor	(	unsigned int	index0or1,
		float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::getColor	(	unsigned int	index0or1,
		float &	r,
		float &	g,
		float &	b,
		float &	a
	)		const

virtual

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::setColor1	(	float	r1,
		float	g1,
		float	b1,
		float	a1
	)

void makVrv::DtLineSegment::setColor2	(	float	r2,
		float	g2,
		float	b2,
		float	a2
	)

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

inline

Reimplemented from makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::setWidth ( float w )

virtual

Set a line width, from 0.0 to 64.0); Default line width is 1.0.

Implements makVrv::DtLineSegmentInterface.

float makVrv::DtLineSegment::width ( ) const

virtual

Get the line width.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::setStippleParameters	(	unsigned int	scale,
		unsigned short	pattern
	)

virtual

Set the line Stipple parameters.

Scale is from 1-256. Pattern is 16 bit mask. Warning Stippled lines are rendered significantly slower than non-Stippled lines. Setting the pattern to NoStipple causes the line not to be stippled anymore.

Implements makVrv::DtLineSegmentInterface.

void makVrv::DtLineSegment::getStippleParameters	(	unsigned int &	scale,
		unsigned short &	pattern
	)		const

virtual

Get the line stipple parameters Uses the two arguments as return values.

Implements makVrv::DtLineSegmentInterface.
