unsigned int osg::ShaderAttribute::addShader ( Shader shader)
inline
unsigned int osg::ShaderAttribute::addUniform ( Uniform uniform)
virtual void osg::ShaderAttribute::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 const char* osg::ShaderAttribute::className ( ) const
inlinevirtual

Return the name of the attribute's class type.

Reimplemented from osg::StateAttribute.

virtual osg::Object* osg::ShaderAttribute::clone ( const osg::CopyOp ) const
inlinevirtual

Clone an attribute, with Object* return type. Must be defined by derived classes.

Implements osg::StateAttribute.

virtual osg::Object* osg::ShaderAttribute::cloneType ( ) const
virtual

Clone the type of an attribute, with Object* return type. Must be defined by derived classes.

Implements osg::StateAttribute.

virtual int osg::ShaderAttribute::compare ( const StateAttribute sa) const
virtual

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

Implements osg::StateAttribute.

virtual void osg::ShaderAttribute::compileGLObjects ( State ) const
virtual

Default to nothing to compile - all state is applied immediately.

Reimplemented from osg::StateAttribute.

virtual bool osg::ShaderAttribute::getModeUsage ( StateAttribute::ModeUsage ) const
virtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

inlinevirtual

Return the name of the attribute's library.

Reimplemented from osg::StateAttribute.

virtual void osg::ShaderAttribute::releaseGLObjects ( State = 0) const
virtual

Release OpenGL objects in specified graphics context if State object is passed, otherwise release OpenGL objects for all graphics context if State object pointer NULL.
