Detailed Description

Sequence is a Group node which allows automatic, time based switching between children.

Constructor & Destructor Documentation

osg::Sequence::Sequence ( )

osg::Sequence::Sequence ( const Sequence & ,

const CopyOp & copyop = CopyOp::SHALLOW_COPY

Member Function Documentation

void osg::Sequence::getDuration ( float & speed,

int & nreps

) const [inline]

Get duration & number of repeats.

void osg::Sequence::getInterval ( LoopMode & mode,

int & begin,

int & end

) const [inline]

Get sequence mode & interval.

SequenceMode osg::Sequence::getMode ( ) const [inline]

Get sequence mode.

float osg::Sequence::getTime ( int frame ) const

Get time for child.

int osg::Sequence::getValue ( ) const [inline]

osg::Sequence::META_Node ( osg ,

Sequence

)

void osg::Sequence::setDuration ( float speed,

int nreps = -1

)

Set duration: speed-up & number of repeats

void osg::Sequence::setInterval ( LoopMode mode,

int begin,

int end

)

Set sequence mode & interval (range of children to be displayed).

void osg::Sequence::setMode ( SequenceMode mode )

Set sequence mode. Start/stop & pause/resume.

void osg::Sequence::setTime ( int frame,

float t

)

Set time in seconds for child.

void osg::Sequence::setValue ( int value ) [inline]

virtual void osg::Sequence::traverse ( NodeVisitor & nv ) [virtual]

Traverse downwards : calls children's accept method with NodeVisitor.
Reimplemented from osg::Group.
