virtual bool osgParticle::PrecipitationEffect::PrecipitationDrawable::supports

(

const osg::PrimitiveFunctor &

)

const [inline, virtual]

Return true if the Drawable subclass supports accept(PrimitiveFunctor&).

Reimplemented from osg::Drawable.

virtual void osgParticle::PrecipitationEffect::PrecipitationDrawable::accept

(

osg::PrimitiveFunctor &

)

const [inline, virtual]

Accept a PrimitiveFunctor and call its methods to tell it about the internal primitives that this Drawable has.

return true if functor handled by drawable, return false on failure of drawable to generate functor calls. Note, PrimtiveFunctor only provides const access of the primitives, as primitives may be procedurally generated so one cannot modify it.

Reimplemented from osg::Drawable.

Return true if the Drawable subclass supports accept(PrimitiveIndexFunctor&).

const [virtual]

drawImplementation(RenderInfo&) is a pure virtual method for the actual implementation of OpenGL drawing calls, such as vertex arrays and primitives, that must be implemented in concrete subclasses of the Drawable base class, examples include osg::Geometry and osg::ShapeDrawable.

drawImplementation(RenderInfo&) is called from the draw(RenderInfo&) method, with the draw method handling management of OpenGL display lists, and drawImplementation(RenderInfo&) handling the actuall drawing itself.

Parameters:

renderInfo

The osg::RenderInfo object that encapulates the current rendering information including the osg::State OpenGL state for the current graphics context.

Implements osg::Drawable.
