Member Function Documentation

virtual void osg::PrimitiveSet::accept ( PrimitiveFunctor functor) const [pure virtual]
virtual void osg::PrimitiveSet::accept ( PrimitiveIndexFunctor functor) const [pure virtual]
virtual const char* osg::PrimitiveSet::className ( ) const [inline, virtual]

return the name of the object's class type.

Must be defined by derived classes.

Implements osg::Object.

Reimplemented in osg::DrawArrays, osg::DrawArrayLengths, osg::DrawElementsUByte, osg::DrawElementsUShort, and osg::DrawElementsUInt.

virtual void osg::PrimitiveSet::computeRange ( ) const [inline, virtual]
virtual void osg::PrimitiveSet::dirty ( ) [inline, virtual]

Dirty the primitive, which increments the modified count, to force buffer objects to update.

Reimplemented in osg::DrawElements.

virtual void osg::PrimitiveSet::draw ( State state,
bool  useVertexBufferObjects 
) const [pure virtual]
virtual const GLvoid* osg::PrimitiveSet::getDataPointer ( ) const [inline, virtual]
virtual DrawElements* osg::PrimitiveSet::getDrawElements ( ) [inline, virtual]

Reimplemented in osg::DrawElements.

virtual const DrawElements* osg::PrimitiveSet::getDrawElements ( ) const [inline, virtual]

Reimplemented in osg::DrawElements.

GLenum osg::PrimitiveSet::getMode ( ) const [inline]
unsigned int osg::PrimitiveSet::getModifiedCount ( ) const [inline]

Get modified count value.

virtual unsigned int osg::PrimitiveSet::getNumIndices ( ) const [pure virtual]

virtual bool osg::PrimitiveSet::isSameKindAs ( const Object obj) const [inline, virtual]
virtual const char* osg::PrimitiveSet::libraryName ( ) const [inline, virtual]

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.

Reimplemented in osg::DrawArrays, osg::DrawArrayLengths, osg::DrawElementsUByte, osg::DrawElementsUShort, and osg::DrawElementsUInt.

virtual void osg::PrimitiveSet::offsetIndices ( int  offset) [pure virtual]
virtual void osg::PrimitiveSet::releaseGLObjects ( State = 0) const [inline, virtual]

If State is non-zero, this function releases OpenGL objects for the specified graphics context.

Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Object.

Reimplemented in osg::DrawElements.

virtual void osg::PrimitiveSet::resizeGLObjectBuffers ( unsigned int  ) [inline, virtual]

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Object.

Reimplemented in osg::DrawElements.
