Constructor & Destructor Documentation

osg::TexGen::TexGen

(

)

osg::TexGen::TexGen	(	const TexGen &	texgen,
		const CopyOp &	copyop = CopyOp::SHALLOW_COPY
	)			[inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

virtual void osg::TexGen::apply

(

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 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

(

ModeUsage &

usage

)

const [inline, virtual]

const Plane& osg::TexGen::getPlane

(

Coord

which

)

const

Plane& osg::TexGen::getPlane

(

Coord

which

)

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.

osg::TexGen::META_StateAttribute	(	osg	,
		TexGen	,
		TEXGEN
	)

void osg::TexGen::setMode

(

Mode

mode

)

[inline]

void osg::TexGen::setPlane	(	Coord	which,
		const Plane &	plane
	)

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.
