Detailed Description

A class representing a Bézier patch.

The Patch class encapsulates the properties and control points of a Bézier patch. It includes methods for initialization, validation, and degree elevation.

Constructor & Destructor Documentation

Patch() [1/6]

Patch::Patch

(

int

a_BiDeg

)

Construct a new Patch object.

Parameters

a_BiDeg

The bi-degree of the patch (same in both u and v directions).

Patch() [2/6]

Patch::Patch	(	int	a_BiDeg,
		std::string	a_Group )

Construct a new Patch object.

Parameters

a_BiDeg	The bi-degree of the patch (same in both u and v directions).
a_Group	The group name associated with the patch.

Patch() [3/6]

Patch::Patch	(	int	a_DegU,
		int	a_DegV )

Construct a new Patch object.

Parameters

a_DegU	The degree of the patch in the u direction.
a_DegV	The degree of the patch in the v direction.

Patch() [4/6]

Patch::Patch	(	int	a_DegU,
		int	a_DegV,
		std::string	a_Group )

Construct a new Patch object.

Parameters

a_DegU	The degree of the patch in the u direction.
a_DegV	The degree of the patch in the v direction.
a_Group	The group name associated with the patch.

Patch() [5/6]

Patch::Patch ( const Patch & other )

default

Copy constructor.

Parameters

other

The Patch object to copy from.

Patch() [6/6]

Patch::Patch ( Patch && other )

defaultnoexcept

Move constructor.

Parameters

other

The Patch object to move from.

Member Function Documentation

degRaise()

void Patch::degRaise

(

)

Raises the degree of the patch by one in both u and v directions.

This method modifies the control points to reflect the degree elevation.

isValid()

bool Patch::isValid

(

)

const

Checks if a patch is valid.

Returns

true if the patch is valid, false otherwise.

operator=() [1/2]

Patch & Patch::operator=

(

const Patch &

other

)

Copy assignment operator.

Parameters

other

Returns

Patch&

operator=() [2/2]

Patch & Patch::operator= ( Patch && other )

noexcept

Move assignment operator.

Parameters

other

Returns

Patch&

Member Data Documentation

m_BBcoefs

std::vector<std::vector<Point> > Patch::m_BBcoefs

Control points of the Bézier patch.

This is a 2D vector where each element represents a control point in 3D space. The size of the outer vector is (m_DegU + 1) and the size of the inner vectors is (m_DegV + 1).
