Member Function Documentation

◆ accept() [1/4]

virtual void osgTerrain::HeightFieldDrawable::accept ( osg::Drawable::AttributeFunctor & )
virtual

accept an AttributeFunctor and call its methods to tell it about the internal attributes that this Drawable has. return true if functor handled by drawable, return false on failure of drawable to generate functor calls.

Reimplemented from osg::Drawable.

◆ accept() [2/4]

virtual void osgTerrain::HeightFieldDrawable::accept ( osg::Drawable::ConstAttributeFunctor & ) const
virtual

Accept an AttributeFunctor and call its methods to tell it about the internal attributes that this Drawable has. return true if functor handled by drawable, return false on failure of drawable to generate functor calls.

Reimplemented from osg::Drawable.

◆ accept() [3/4]

virtual void osgTerrain::HeightFieldDrawable::accept ( osg::PrimitiveFunctor & ) const
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, PrimitiveFunctor only provides const access of the primitives, as primitives may be procedurally generated so one cannot modify it.

Reimplemented from osg::Drawable.

◆ accept() [4/4]

virtual void osgTerrain::HeightFieldDrawable::accept ( osg::PrimitiveIndexFunctor & ) const
virtual

Accept a PrimitiveIndexFunctor 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, PrimitiveIndexFunctor only provide const access of the primitives, as primitives may be procedurally generated so one cannot modify it.

Reimplemented from osg::Drawable.

◆ compileGLObjects()

virtual void osgTerrain::HeightFieldDrawable::compileGLObjects ( osg::RenderInfo & renderInfo) const
virtual

Immediately compile this Drawable into an OpenGL Display List/VertexBufferObjects.

Note
Operation is ignored if _useDisplayList is false or VertexBufferObjects are not used.

Reimplemented from osg::Drawable.

◆ drawImplementation()

virtual void osgTerrain::HeightFieldDrawable::drawImplementation ( osg::RenderInfo & ) 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 actual drawing itself. renderInfo : The osg::RenderInfo object that encapsulates the current rendering information including the osg::State OpenGL state for the current graphics context.
