Member Function Documentation

virtual void osg::PrimitiveSet::accept ( PrimitiveFunctor &  functor  )  const [pure virtual]

Implemented in osg::DrawArrays.

virtual void osg::PrimitiveSet::accept ( PrimitiveIndexFunctor &  functor  )  const [pure virtual]

Implemented in osg::DrawArrays.

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.

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]

Implemented in osg::DrawArrays.

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]

Implemented in osg::DrawArrays.

int osg::PrimitiveSet::getNumInstances (  )  const [inline]

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

Reimplemented from osg::Object.

Reimplemented in osg::DrawArrays.

References NULL.

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.

virtual void osg::PrimitiveSet::offsetIndices ( int  offset  )  [pure virtual]

Implemented in osg::DrawArrays.

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.

void osg::PrimitiveSet::setMode ( GLenum  mode  )  [inline]
void osg::PrimitiveSet::setModifiedCount ( unsigned int  value  )  [inline]

Set the modified count value.

void osg::PrimitiveSet::setNumInstances ( int  n  )  [inline]
virtual bool osg::PrimitiveSet::supportsBufferObject (  )  const [inline, virtual]
