Member Function Documentation

virtual void osg::PointSprite::apply ( osg::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 bool osg::PointSprite::checkValidityOfAssociatedModes ( osg::State ) const
virtual

Check the modes associated with this StateAttribute are supported by current OpenGL drivers, and if not set the associated mode in osg::State to be black listed/invalid. Return true if all associated modes are valid.

Reimplemented from osg::StateAttribute.

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

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

Implements osg::StateAttribute.

CoordOriginMode osg::PointSprite::getCoordOriginMode ( ) const
inline
virtual bool osg::PointSprite::getModeUsage ( StateAttribute::ModeUsage ) const
inlinevirtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References GL_POINT_SPRITE_ARB, and osg::StateAttribute::ModeUsage::usesMode().

static bool osg::PointSprite::isPointSpriteSupported ( unsigned int  context)
static
virtual bool osg::PointSprite::isTextureAttribute ( ) const
inlinevirtual

Return true if StateAttribute is a type which controls texturing and needs to be issued w.r.t to specific texture unit.

Reimplemented from osg::StateAttribute.
