Detailed Description

Pure virtual base class for drawable geometry. In OSG, everything that can be rendered is implemented as a class derived from Drawable. The Drawable class contains no drawing primitives, since these are provided by subclasses such as osg::Geometry.

Notice that a Drawable is not a Node, and therefore it cannot be directly added to a scene graph. Instead, Drawables are attached to Geodes, which are scene graph nodes.

The OpenGL state that must be used when rendering a Drawable is represented by a StateSet. Since a Drawable has a reference (osg::ref_ptr) to a StateSet, StateSets can be shared between different Drawables. In fact, sharing StateSets is a good way to improve performance, since this allows OSG to reduce the number of expensive changes in the OpenGL state.

Finally, Drawables can also be shared between different Geodes, so that the same geometry (loaded to memory just once) can be used in different parts of the scene graph.

Reimplemented in osg::Geometry.

static void osg::Drawable::discardAllDeletedDisplayLists ( unsigned int contextID )

static

Flush all the cached display list which need to be deleted in the OpenGL context related to contextID. Note, unlike flush no OpenGL calls are made, instead the handles are all removed. this call is useful for when an OpenGL context has been destroyed.

void osg::Drawable::draw ( RenderInfo & renderInfo ) const

inline

Draw OpenGL primitives. If the Drawable has _useDisplayList set to true, then use an OpenGL display list, automatically compiling one if required. Otherwise, call drawImplementation().

Note: This method should not be overridden in subclasses, as it manages the optional display list (notice this is not even virtual). Subclasses should override drawImplementation() instead.

Here is the call graph for this function:

virtual void osg::Drawable::drawImplementation ( RenderInfo & ) const

inlinevirtual

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.
