class SpacingContour3DConstraint : public Constraint

a class corresponding to a position constraint where the distance between 2 vertices is constrained to belong to an interval [minimumDistance,maximumDistance]

Inheritance:

Public Methods

virtual void	apply () the apply fonction that adds or removes vertices depending on minimumDistance and maximumDistance
double	getMinimumSpacing () const returns the minimum spacing between two vertices
double	getMaximumSpacing () const returns the maximum spacing between two vertices
void	setMinimumSpacing (const double min) sets the minimum spacing between two vertices
void	setMaximumSpacing (const double max) sets the maximum spacing between two vertices

Public

	Exception classes class MissingContour : public Exception thrown when a SpacingConstraint is created specifying without any contour
	constructor SpacingContour3DConstraint (const unsigned int freq, const double min, const double max, ActiveContour3D *c) throw(MissingContour) create a spacing constraint
	destructor virtual ~SpacingContour3DConstraint (void) empty destructor

Private Fields

double	minimumSpacing the minimum Spacing between two vertices : may be set to zero
double	maximumSpacing the maximum Spacing between two vertices
ActiveContour3D*	contour the ActiveContour3D where the constraint is applied

Exception classes

class MissingContour: public Exception

thrown when a SpacingConstraint is created specifying without any contour

double minimumSpacing

the minimum Spacing between two vertices : may be set to zero

double maximumSpacing

the maximum Spacing between two vertices

ActiveContour3D* contour

the ActiveContour3D where the constraint is applied

virtual void apply()

the apply fonction that adds or removes vertices depending on minimumDistance and maximumDistance

double getMinimumSpacing() const

returns the minimum spacing between two vertices

double getMaximumSpacing() const

returns the maximum spacing between two vertices

void setMinimumSpacing(const double min)

sets the minimum spacing between two vertices

void setMaximumSpacing(const double max)

constructor

SpacingContour3DConstraint(const unsigned int freq, const double min, const double max, ActiveContour3D *c) throw(MissingContour)

create a spacing constraint

Throws:

MissingContour thrown when c is NULL

Parameters:

freq - the frequency at which the constraint is applied
min - the minimum spacing value defined as a percentage of the median edge length
max - the maximum spacing value defined as a percentage of the median edge length
c - the ontour on which the constraint applies

destructor

virtual ~SpacingContour3DConstraint(void)

empty destructor
