Member Function Documentation

virtual void makVrv::DtSharedDrawElementsUInt::setIndexBounds ( unsigned int  start, unsigned int  count  )

virtual

Set the index bounds. This allows for independent start and sizes of elements while still sharing the same buffer.

virtual void makVrv::DtSharedDrawElementsUInt::getIndexBounds ( unsigned int &  start, unsigned int &  count  ) const

virtual

virtual osg::Object* makVrv::DtSharedDrawElementsUInt::cloneType ( ) const

inlineoverridevirtual

All of the remaining functions are simply necessary to implement the DrawElements API forwarded to the indices member.

overridevirtual

virtual void makVrv::DtSharedDrawElementsUInt::resizeGLObjectBuffers ( unsigned int  maxSize )

overridevirtual

Resize any per context GLObject buffers to specified size.

virtual void makVrv::DtSharedDrawElementsUInt::releaseGLObjects ( osg::State *  state = 0 ) const

overridevirtual

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

Otherwise, releases OpenGL objects for all graphics contexts.

virtual void makVrv::DtSharedDrawElementsUInt::computeRange ( ) const

overridevirtual

virtual void makVrv::DtSharedDrawElementsUInt::draw ( osg::State &  state, bool  useVertexBufferObjects  ) const

overridevirtual

Draw override.
