osg::TexMat::TexMat	(	const TexMat &	texmat,
		const CopyOp &	copyop = `CopyOp::SHALLOW_COPY`

Member Function Documentation

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

virtual

Apply texture matrix to OpenGL state.

Reimplemented from osg::StateAttribute.

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.

Definition at line 43 of file TexMat.h.

Matrix& osg::TexMat::getMatrix ( )

inline

Get the texture matrix

Definition at line 59 of file TexMat.h.

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

inline

Get the const texture matrix

Definition at line 62 of file TexMat.h.

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.

Definition at line 72 of file TexMat.h.

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.

Definition at line 40 of file TexMat.h.

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

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

inline

Set the texture matrix

Definition at line 56 of file TexMat.h.

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.
