Constructor & Destructor Documentation

osg::Stencil::Stencil (  ) 
osg::Stencil::Stencil ( const Stencil stencil,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::Stencil::~Stencil (  )  [protected, virtual]

Member Function Documentation

virtual void osg::Stencil::apply ( State  )  const [virtual]

apply the OpenGL state attributes. The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from osg::StateAttribute.

virtual int osg::Stencil::compare ( const StateAttribute sa  )  const [inline, virtual]

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

Function osg::Stencil::getFunction (  )  const [inline]
unsigned int osg::Stencil::getFunctionMask (  )  const [inline]
int osg::Stencil::getFunctionRef (  )  const [inline]
virtual bool osg::Stencil::getModeUsage ( StateAttribute::ModeUsage  )  const [inline, virtual]

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References osg::StateAttribute::ModeUsage::usesMode().

Operation osg::Stencil::getStencilFailOperation (  )  const [inline]

get the operation when the stencil test fails.

Operation osg::Stencil::getStencilPassAndDepthFailOperation (  )  const [inline]

get the operation when the stencil test passes but the depth test fails.

Operation osg::Stencil::getStencilPassAndDepthPassOperation (  )  const [inline]

get the operation when both the stencil test and the depth test pass.

unsigned int osg::Stencil::getWriteMask (  )  const [inline]

void osg::Stencil::setFunctionRef ( int  ref  )  [inline]
void osg::Stencil::setOperation ( Operation  sfail,
Operation  zfail,
Operation  zpass 
) [inline]

set the operations to apply when the various stencil and depth tests fail or pass. First parameter is to control the operation when the stencil test fails. The second parameter is to control the operation when the stencil test passes, but depth test fails. The third parameter controls the operation when both the stencil test and depth pass. Ordering of parameter is the same as if using glStencilOp(,,).

void osg::Stencil::setStencilFailOperation ( Operation  sfail  )  [inline]

set the operation when the stencil test fails.

void osg::Stencil::setStencilPassAndDepthFailOperation ( Operation  zfail  )  [inline]

set the operation when the stencil test passes but the depth test fails.

void osg::Stencil::setStencilPassAndDepthPassOperation ( Operation  zpass  )  [inline]

set the operation when both the stencil test and the depth test pass.

void osg::Stencil::setWriteMask ( unsigned int  mask  )  [inline]
