Member Function Documentation

◆ apply()

virtual void osg::TexMat::apply ( State & state ) const

virtual

Apply texture matrix to OpenGL state.

Reimplemented from osg::StateAttribute.

◆ compare()

virtual int osg::TexMat::compare ( const StateAttribute & sa ) const

inlinevirtual

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

Implements osg::StateAttribute.

◆ getMatrix() [1/2]

Matrix & osg::TexMat::getMatrix ( )

inline

Get the texture matrix

References _matrix.

◆ getMatrix() [2/2]

const Matrix & osg::TexMat::getMatrix ( ) const

inline

Get the const texture matrix

References _matrix.

◆ getScaleByTextureRectangleSize()

bool osg::TexMat::getScaleByTextureRectangleSize ( ) const

inline

Get whether the post scaling of the TexMat matrix, by the size of the last applied texture rectangle, is switched on/off.

References _scaleByTextureRectangleSize.

◆ isTextureAttribute()

virtual bool osg::TexMat::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::TexMat::META_StateAttribute	(	osg	,
		TexMat	,
		TEXMAT	)

References osg::StateAttribute::TEXMAT, and TexMat().

◆ setMatrix()

void osg::TexMat::setMatrix ( const Matrix & matrix )

inline

Set the texture matrix

References _matrix.

◆ setScaleByTextureRectangleSize()

void osg::TexMat::setScaleByTextureRectangleSize ( bool flag )

inline

Switch on/off the post scaling of the TexMat matrix by the size of the last applied texture rectangle. Use a TexMat alongside a TextureRectangle with this scaling applied allows one to treat a TextureRectnagles texture coordinate range as if it were the usual non dimensional 0.0 to 1.0 range. Note, the TexMat matrix itself is not modified by the post scaling, its purely an operation passed to OpenGL to do the post scaling once the the TexMat matrix has been loaded.
