Implements makVrv::DtSegmentedLineInterface.

virtual unsigned int makVrv::DtSegmentedLine::vertexCount ( ) const
overridevirtual

Get the vertex count. This count will always be one more than the number of segments available. Use segment count to get the number of segments.

Implements makVrv::DtSegmentedLineInterface.

overridevirtual

Number of segments available.

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::set3DPosition ( unsigned int  vertexIndex,
float  x,
float  y,
float  z,
float  w 
)
overridevirtual

Set one vertex position. NOTE it is much more efficient to update all vertices using setPositions If several change.

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::get3DPosition ( unsigned int  vertexIndex,
float &  x,
float &  y,
float &  z,

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::set3DDirection ( unsigned int  vertexIndex,
float  x,
float  y,
float  z 
)
overridevirtual

Set the normalized direction of the line in world space.

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::get3DDirection ( unsigned int  vertexIndex,
float &  x,
float &  y,
float &  z 
) const
overridevirtual

Get the normalized direction of the vertex.

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::setDirection2DLength ( unsigned int  vertexIndex,
float  length

Implements makVrv::DtSegmentedLineInterface.

virtual void makVrv::DtSegmentedLine::setGroup ( int  )
overridevirtual

The higher the z order the "closer" to the eyepoint this element will be drawn. Use this variable to stack overlay objects in the particular order you want them displayed.
