Constructor & Destructor Documentation

NurbsSurfaceValues()

NurbsSurfaceValues::NurbsSurfaceValues

(

)

Default constructor.

Constructor of parameters of non-closed spline surface of second order along the u and v directions.

Member Function Documentation

InitMesh() [1/2]

bool NurbsSurfaceValues::InitMesh	(	ptrdiff_t	uDeg,
		bool	uCls,
		ptrdiff_t	vDeg,
		bool	vCls,
		const Array2< MbCartPoint3D > &	pnts,
		bool	checkSelfInt
	)

Initialization by grid of points.

Initialization of parameters of spline surface by grid of points.

Parameters

[in]	uDeg,vDeg	- Order along u and v.
[in]	uCls,vCls	- Attribute of surface closedness along u and v.
[in]	pnts	- A point set.
[in]	checkSelfInt	- Attribute of check for self-intersection.

Returns

False if incorrect parameters.

InitMesh() [2/2]

bool NurbsSurfaceValues::InitMesh	(	ptrdiff_t	uDeg,
		bool	uCls,
		ptrdiff_t	vDeg,
		bool	vCls,
		const Array2< MbCartPoint3D > &	pnts,
		const Array2< double > *	wts,
		bool	checkSelfInt
	)

Initialization by grid of points.

Initialization of parameters of spline surface by grid of points.

Parameters

[in]	uDeg,vDeg	- Order along u and v.
[in]	uCls,vCls	- Attribute of surface closedness along u and v.
[in]	pnts	- A point set.
[in]	wts	- Weights of points.
[in]	checkSelfInt	- Attribute of check for self-intersection.

Returns

False if incorrect parameters.

InitCloud()

bool NurbsSurfaceValues::InitCloud	(	ptrdiff_t	uvDeg,
		const Array2< MbCartPoint3D > &	pnts,
		const MbPlacement3D *	cloudPlace,
		bool	checkSelfInt
	)

Initialization by point cloud.

Initialization by point cloud (used the original plane).
If uvDeg < 0, then set of triangular plates is created
(by triangulation of points projections on the cloudPlace)

Parameters

[in]	uvDeg	- Order along u and v.
[in]	pnts	- Set of points. Set of points is suitable for initialization (is a point cloud) if it is one-dimensional array of points which don't lie on a straight line without coincidence.
[in]	cloudPlace	- Support plane of point cloud.
[in]	checkSelfInt	- Attribute of check for self-intersection.

Returns

True if correct parameters.

GetMinCloudDegree()

ptrdiff_t NurbsSurfaceValues::GetMinCloudDegree ( ) const

inline

The smallest possible order of splines in the case of point cloud.

Request after the successful creation of the surface otherwise returns a negative value.

GetMaxCloudDegree()

ptrdiff_t NurbsSurfaceValues::GetMaxCloudDegree ( ) const

inline

The maximum possible order of splines in the case of point cloud.

The maximum possible order of splines in the case of point cloud.
Request after the successful creation of the surface otherwise returns a negative value.
