Constructor & Destructor Documentation

BlendAnalytic::BlendAnalytic	(	const double &	r,
		const double &	s
	)

Stores the radius of influence and the strength (maximum intensity).

Parameters

r	Radius.
s	Strength.

void BlendAnalytic::Alpha ( const double & t )

virtual

Scales the maximum intensity of the blending function.

This function scales the internal strength parameter of the blending function radius, as well as the Lipschitz constant.

Reimplemented from BlendCompact.

void BlendAnalytic::Scale ( const double & t )

virtual

Scales the radius if the blending function.

This function scales the internal radius, as well as the Lipschitz constant.

Reimplemented from BlendCompact.
