Member Function Documentation

virtual void osg::PointSprite::apply

(

osg::State &

state

)

const [virtual]

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

Implements 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.

virtual bool osg::PointSprite::getModeUsage

[static]

virtual bool osg::PointSprite::isTextureAttribute

(

)

const [inline, virtual]

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.
