Detailed Description

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

Member Function Documentation

int osg::Sequence::_getNextValue ( void  )
protected
void osg::Sequence::_update ( void  )
protected
virtual bool osg::Sequence::addChild ( Node child)
virtual

Add Node to Group. If node is not NULL and is not contained in Group then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.

Reimplemented from osg::Group.

virtual bool osg::Sequence::addChild ( Node child,
double  t 
)
virtual
int osg::Sequence::getBegin ( ) const
inline

Get interval beginning.

bool osg::Sequence::getClearOnStop ( ) const
inline

Get whether to show no child nodes after stopping

double osg::Sequence::getDefaultTime ( void  ) const
inline

Get default time in seconds for new child.

void osg::Sequence::getDuration ( float &  speed,
int &  nreps 
) const
inline

Get duration & number of repeats.

int osg::Sequence::getEnd ( ) const
inline

Get interval ending.

void osg::Sequence::getInterval ( LoopMode mode,
int &  begin,
int &  end 
) const
inline

Get sequence mode & interval.

double osg::Sequence::getLastFrameTime ( void  ) const
inline

Get last frame time in seconds

LoopMode osg::Sequence::getLoopMode ( ) const
inline

Get sequence mode.

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

Get sequence mode.

unsigned int osg::Sequence::getNumFrames ( ) const
inline

Get number of frames

int osg::Sequence::getNumRepeats ( ) const
inline

Get number of repeats.

float osg::Sequence::getSpeed ( ) const
inline

Get speed.

bool osg::Sequence::getSync ( ) const
inline

Get sync value

double osg::Sequence::getTime ( unsigned int  frame) const

Get time for child.

const std::vector<double>& osg::Sequence::getTimeList ( ) const
inline

Get the time list for children.

int osg::Sequence::getValue ( ) const
inline
virtual bool osg::Sequence::insertChild ( unsigned int  index,
Node child 
)
virtual

Insert Node to Group at specific location. The new child node is inserted into the child list before the node at the specified index. No nodes are removed from the group with this operation.

Reimplemented from osg::Group.

virtual bool osg::Sequence::insertChild ( unsigned int  index,
Node child,
double  t 
)
virtual
osg::Sequence::META_Node ( osg  ,
Sequence   
)
virtual bool osg::Sequence::removeChild ( Node child)
virtual
virtual bool osg::Sequence::removeChildren ( unsigned int  pos,
unsigned int  numChildrenToRemove 
)
virtual

Remove children from Group. Note, must be override by subclasses of Group which add per child attributes.

Reimplemented from osg::Group.

void osg::Sequence::setBegin ( int  begin)
inline

Set interval beginning.

void osg::Sequence::setClearOnStop ( bool  clearOnStop)
inline

If true, show no child nodes after stopping

void osg::Sequence::setDefaultTime ( double  t)
inline

Set default time in seconds for new child. if t<0, t=0

void osg::Sequence::setDuration ( float  speed,
int  nreps = -1 
)

Set duration: speed-up & number of repeats

void osg::Sequence::setEnd ( int  end)
inline

Set interval ending.

void osg::Sequence::setInterval ( LoopMode  mode,
int  begin,
int  end 
)

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

void osg::Sequence::setLastFrameTime ( double  t)
inline

Set time of last frame of last loop, in seconds. if t<= 0, then ignored

void osg::Sequence::setLoopMode ( LoopMode  mode)
inline

Set sequence mode.

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

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

void osg::Sequence::setNumRepeats ( int  nreps)
inline

Set number of repeats.

void osg::Sequence::setSpeed ( float  speed)
inline

Set speed.

void osg::Sequence::setSync ( bool  sync)
inline

If false (default), frames will not be sync'd to frameTime. If true, frames will be sync'd to frameTime.

void osg::Sequence::setTime ( unsigned int  frame,
double  t 
)

Set time in seconds for child.

void osg::Sequence::setTimeList ( const std::vector< double > &  timeList)
inline

Set the time list for children.

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

value is which child node is to be displayed

virtual void osg::Sequence::traverse ( NodeVisitor )
virtual

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Group.
