Member Function Documentation

virtual const char* osgParticle::Interpolator::className ( ) const
inlinevirtual

return the name of the object's class type.

Must be defined by derived classes.

Implements osg::Object.

virtual float osgParticle::Interpolator::interpolate ( float  t,
float  y1,
float  y2 
) const
pure virtual

Interpolate between floats. Must be overriden in descendant classes.

Implemented in osgParticle::LinearInterpolator.

Referenced by interpolate().

virtual osg::Vec2 osgParticle::Interpolator::interpolate ( float  t,
const osg::Vec2 y1,
const osg::Vec2 y2 
) const
inlinevirtual

Interpolate between 2-dimensional vectors. Default behavior is to interpolate each component separately.

References interpolate(), osg::Vec2f::x(), and osg::Vec2f::y().

virtual osg::Vec3 osgParticle::Interpolator::interpolate ( float  t,
const osg::Vec3 y1,
const osg::Vec3 y2 
) const
inlinevirtual

Interpolate between 3-dimensional vectors. Default behavior is to interpolate each component separately.

References interpolate(), osg::Vec3f::x(), osg::Vec3f::y(), and osg::Vec3f::z().

virtual osg::Vec4 osgParticle::Interpolator::interpolate ( float  t,
const osg::Vec4 y1,
const osg::Vec4 y2 
) const
inlinevirtual

Interpolate between 4-dimensional vectors. Default behavior is to interpolate each component separately.

References interpolate(), osg::Vec4f::w(), osg::Vec4f::x(), osg::Vec4f::y(), and osg::Vec4f::z().

ValueType osgParticle::Interpolator::interpolate ( float  t,
const range< ValueType > &  r 
) const
inline
virtual bool osgParticle::Interpolator::isSameKindAs ( const osg::Object obj) const
inlinevirtual

Reimplemented from osg::Object.

virtual const char* osgParticle::Interpolator::libraryName ( ) const
inlinevirtual

return the name of the object's library.

Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Implements osg::Object.
