Detailed Description

This class is an OSG Callback which allows simple linear translation of a matrix transform node along a specified axis.

It is controlled by a WPropDouble. This way, one can simply implement movable slices and similar.

Template Parameters

T	the type used as control mechanism. Typically, this should be an property whose type is cast-able to double. The type specified must support access via T->get(). Specialize the class if you do not specify a pointer.

Constructor & Destructor Documentation

template<typename T >

WGELinearTranslationCallback< T >::WGELinearTranslationCallback	(	osg::Vec3	axe,
		T	property,
		osg::ref_ptr< osg::TexMat >	texMatrix,
		double	scaler = `1.0`
	)

Constructor.

Creates the callback. You still need to add it to the desired node.

Parameters

axe	the axe to translate along. Should be normalized. If not, it scales the translation.
property	the property containing the value
texMatrix	optional pointer to a texture matrix which can be modified too to contain the normalized translation.
scaler	scales the property by this value before creating the matrix.

template<typename T >

WGELinearTranslationCallback< T >::WGELinearTranslationCallback	(	osg::Vec3	axe,
		T	property,
		osg::ref_ptr< osg::Uniform >	uniform,
		double	scaler = `1.0`
	)

Constructor.

Creates the callback. You still need to add it to the desired node.

Parameters

axe	the axe to translate along. Should be normalized. If not, it scales the translation.
property	the property containing the value
uniform	optional pointer to a uniform that will contain the matrix. Useful if no tex-matrix is available anymore. The matrix is the matrix that is NOT scaled to be in texture space.
scaler	scales the property by this value before creating the matrix.

template<typename T >

WGELinearTranslationCallback< T >::WGELinearTranslationCallback	(	osg::Vec3	axe,
		T	property,
		double	scaler = `1.0`
	)

Constructor.

Creates the callback. You still need to add it to the desired node.

Parameters

axe	the axe to translate along. Should be normalized. If not, it scales the translation.
property	the property containing the value
scaler	scales the property by this value before creating the matrix.
