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.

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

Reimplemented from makVrv::DtLineSegmentInterface.

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.

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, float  r2, float  g2, float  b2, float  a2  )

virtual

Set the vertex colors.

Implements makVrv::DtLineSegmentInterface.

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