Member Function Documentation

virtual DtLineSegmentInterface* makVrv::DtTexturedLine::createAndInitNewSegment ( )

virtual

Creates and initializes a new segment.

Reimplemented from makVrv::DtSegmentedLine.

virtual void makVrv::DtTexturedLine::setTexture ( DtOverlayResourceProvider::NativeResourceHandle  texture, float  textureWidth  )

virtual

Sets the texture to use with the line.

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

virtual

Sets the factor by which to adjust distance.

The zoom factor will be used to determine how to repeat the textured pattern on the line.

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

virtual

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

virtual void makVrv::DtTexturedLine::setGroup ( int  )

virtual

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

Reimplemented from makVrv::DtSegmentedLine.

virtual void makVrv::DtTexturedLine::removeLineSegmentsUntilEndFrom ( int  segmentCount )

protectedvirtual

Removed segments from the line starting at segmentCount until the end is reached.

Reimplemented from makVrv::DtSegmentedLine.

virtual void makVrv::DtTexturedLine::setLineSegment ( int  , DtLineSegmentInterface *    )

protectedvirtual

Sets the segment into the array. If array is smaller, increases size.

Reimplemented from makVrv::DtSegmentedLine.
