Member Function Documentation

void makVrv::DtTexturedLineSegment::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::DtTexturedLineSegment::group ( ) const

virtual

Get the group.

Implements makVrv::DtLineSegmentInterface.

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

virtual

Set the first vertex position.

Implements makVrv::DtLineSegmentInterface.

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

virtual

Implements makVrv::DtLineSegmentInterface.

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

virtual

Implements makVrv::DtLineSegmentInterface.

		float	g,
		float	b,
		float	a
	)

void makVrv::DtTexturedLineSegment::getColor	(	float &	r,
		float &	g,
		float &	b,
		float &	a
	)		const

void makVrv::DtTexturedLineSegment::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::DtTexturedLineSegment::width ( ) const

virtual

Get the line width.

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtTexturedLineSegment::setTextureParameters	(	DtOverlayResourceProvider::NativeResourceHandle	texture,
		float	myTextureWidth,
		float	left = `0.0f`,
		float	right = `1.0f`,
		float	bottom = `0.0f`,
		float	top = `1.0f`
	)

virtual

Sets the parameters for the textured line. values other than 1 will cause repeating of the texture. Texture width is used to determine the width of the texture. Set larger/smaller width than texture to produce texture scaling.

virtual void makVrv::DtTexturedLineSegment::setZoomFactor ( float z )

virtual

Sets the factor by which to adjust distance.

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

virtual

Sets the 2D position of the line segment.

Implements makVrv::DtLineSegmentInterface.

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

virtual

Implements makVrv::DtLineSegmentInterface.

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

virtual

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtTexturedLineSegment::setColors	(	float	r1,
		float	g1,
		float	b1,
		float	a1,

	)

virtual

Set the vertex colors.

Implements makVrv::DtLineSegmentInterface.

virtual void makVrv::DtTexturedLineSegment::setRotationOffset ( float )

virtual

Sets the offset to the rotation to apply to the segmented line. Use for observer rotation.
