virtual void makVrv::DtOsgParticleRibbon::update ( double  dt, double  simTime  )

overridevirtual

Override the behavior of the osg ribbon.

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgParticleRibbon::setAlphaVelocity ( float  alphaVelocity )

virtual

Set the rate in units/second at which the alpha values of particles change.

virtual void makVrv::DtOsgParticleRibbon::setTextureRepeat ( float  textureRepeat )

virtual

Set the number of copies of the texture to repeat into each quad. Textures are tiled in their v coordinate only.

virtual void makVrv::DtOsgParticleRibbon::setNewParticlesVisible ( bool  enable )

virtual

If true then particles are created normally. If false than all new particles have an alpha of 0 so they are still created but not visible and the transition from off to on is not a sudden one.

virtual void makVrv::DtOsgParticleRibbon::addParticle ( osg::Vec3d const &  left, osg::Vec3d const &  right, double  simTime  )

overrideprotectedvirtual

Add a particle to the ribbon.

Implements makVrv::DtOsgRibbon.

virtual float makVrv::DtOsgParticleRibbon::currentSegmentLength ( )

overrideprotectedvirtual

Find the length of the current ribbon segment.

Implements makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgParticleRibbon::cleanupOldSegments ( double  simTime )

overrideprotectedvirtual

Check to see if any segments have reached their timeout if so remove them from the list to be rendered. currently only implemented for track histories.

Implements makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgParticleRibbon::extendCurrentSegment ( osg::Vec3d const &  left, osg::Vec3d const &  right, double  simTime  )

overrideprotectedvirtual

Extend the current segment to left and right points.

Implements makVrv::DtOsgRibbon.

virtual osg::Drawable* makVrv::DtOsgParticleRibbon::getDrawable ( )

overrideprotectedvirtual

Create or get the ribbon drawable.

Implements makVrv::DtOsgRibbon.

virtual osg::Geode* makVrv::DtOsgParticleRibbon::createGeode ( )

overrideprotectedvirtual

Create the geode to re-render the ribbon.

Reimplemented from makVrv::DtOsgRibbon.

virtual int makVrv::DtOsgParticleRibbon::particleIndexAtOffset ( int  offset )

protectedvirtual

Get index of particle at offset from current particle.

virtual void makVrv::DtOsgParticleRibbon::updateParticles ( double  dt )

protectedvirtual

Update the particles with given time change.

virtual void makVrv::DtOsgParticleRibbon::updateGeometryFromParticles ( double  dt )

protectedvirtual

Update the underlying geometry from the particles' list with the given time change.

virtual osg::Vec2 makVrv::DtOsgParticleRibbon::getTextureCoordinateFor ( int  pointIndex, float  vScale  ) const
