Detailed Description

template<typename T>
class WGELinearTranslationCallback< T >

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:

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
	)

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.

template<typename T >

WGELinearTranslationCallback< T >::WGELinearTranslationCallback	(	osg::Vec3	axe,
		T	property,
		osg::ref_ptr< osg::Uniform >	uniform
	)

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.
