Constructor & Destructor Documentation

◆ TexGen() [1/2]

osg::TexGen::TexGen ( )

◆ TexGen() [2/2]

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

Copy constructor using CopyOp to manage deep vs shallow copy.

References _mode, _plane_q, _plane_r, _plane_s, _plane_t, osg::CopyOp::SHALLOW_COPY, osg::StateAttribute::StateAttribute(), and TexGen().

◆ ~TexGen()

virtual osg::TexGen::~TexGen ( void )
protectedvirtual

Member Function Documentation

◆ apply()

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.

◆ compare()

virtual int osg::TexGen::compare ( const StateAttribute & sa) const
inlinevirtual

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

Implements osg::StateAttribute.

References _mode, _plane_q, _plane_r, _plane_s, _plane_t, COMPARE_StateAttribute_Parameter, COMPARE_StateAttribute_Types, osg::StateAttribute::StateAttribute(), and TexGen().

◆ getMode()

Mode osg::TexGen::getMode ( ) const
inline

References _mode.

◆ getModeUsage()

virtual bool osg::TexGen::getModeUsage ( StateAttribute::ModeUsage & ) const
inlinevirtual

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References osg::StateAttribute::ModeUsage::usesTextureMode().

◆ getPlane() [1/2]

Plane & osg::TexGen::getPlane ( Coord which)

◆ getPlane() [2/2]

const Plane & osg::TexGen::getPlane ( Coord which) const

◆ isTextureAttribute()

virtual bool osg::TexGen::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.

◆ META_StateAttribute()

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

◆ setMode()

void osg::TexGen::setMode ( Mode mode)
inline

References _mode.

◆ setPlane()

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

◆ setPlanesFromMatrix()

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.
