Detailed Description

Encapsulate OpenGL glStencilFunc/Op/Mask functions.

All functionality except INCR_WRAP and DECR_WRAP is supported by OpenGL 1.1. INCR_WRAP an DECR_WRAP are available since OpenGL 1.4 or when GL_EXT_stencil_wrap extension is present.

If INCR_WRAP or DECR_WRAP values are used while they are detected to be not supported, the INCR or DECR values are sent to OpenGL instead.

OpenGL 2.0 introduced two side stenciling that is available through osg::StencilTwoSided class.

Member Function Documentation

◆ apply()

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.

◆ compare()

virtual int osg::Stencil::compare ( const StateAttribute & sa) const
inlinevirtual

◆ getFunction()

Function osg::Stencil::getFunction ( ) const
inline

References _func.

◆ getFunctionMask()

unsigned int osg::Stencil::getFunctionMask ( ) const
inline

References _funcMask.

◆ getFunctionRef()

int osg::Stencil::getFunctionRef ( ) const
inline

References _funcRef.

◆ getModeUsage()

virtual bool osg::Stencil::getModeUsage ( StateAttribute::ModeUsage & ) const
inlinevirtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

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

◆ getStencilFailOperation()

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

get the operation when the stencil test fails.

References _sfail.

◆ getStencilPassAndDepthFailOperation()

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

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

References _zfail.

◆ getStencilPassAndDepthPassOperation()

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

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

References _zpass.

◆ getWriteMask()

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

References _writeMask.

inline

References _funcMask.

◆ setFunctionRef()

void osg::Stencil::setFunctionRef ( int ref)
inline

References _funcRef, and osg::Referenced::ref().

◆ setOperation()

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(,,).

References _sfail, _zfail, and _zpass.

◆ setStencilFailOperation()

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

set the operation when the stencil test fails.

References _sfail.

◆ setStencilPassAndDepthFailOperation()

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

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

References _zfail.

◆ setStencilPassAndDepthPassOperation()

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

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

References _zpass.

◆ setWriteMask()

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

References _writeMask.
