osg::TexGen::TexGen | ( | const TexGen & | texgen, |
const CopyOp & | copyop = CopyOp::SHALLOW_COPY |
||
) | [inline] |
Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::TexGen::~TexGen | ( | void | ) | [protected, virtual] |
virtual void osg::TexGen::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::TexGen::compare | ( | const StateAttribute & | sa | ) | const [inline, virtual] |
Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.

Mode osg::TexGen::getMode | ( | ) | const [inline] |
virtual bool osg::TexGen::getModeUsage | ( | StateAttribute::ModeUsage & | ) | const [inline, virtual] |
Return the modes associated with this StateAttribute.
Reimplemented from osg::StateAttribute.
References osg::StateAttribute::ModeUsage::usesTextureMode().
virtual bool osg::TexGen::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.

void osg::TexGen::setMode | ( | Mode | mode | ) | [inline] |
void osg::TexGen::setPlanesFromMatrix | ( | const Matrixd & | matrix | ) |
Set the tex gen planes from specified matrix.
Typical usage would be to pass in a projection matrix to set up projective texturing.
