Detailed Description

This class represents the boundary geometry (face loops) on a bounded surface.

Remarks: Each face loop consists of four arrays:

3D curve or position pointers 2D parameter space curve pointers 3D orientations 2D orientations

There is a one-to-one correspondence between elements in the arrays, although certain elements of a given array could be NULL, or meaningless.

Loop degeneracies are represented as follows:

The entire loop degenerates to a single model space point, which is represented by the tuple (numElements = 1, position3d, curve2d). The curve2d may be NULL. The edge sense, and the curve2d sense are irrelevant. isDegenerate() method allows the determination of this condition on a loop. A loop consisting of one or more model space degeneracies is represented as the general case with those edges that are degenerate represented by position3d. This implies that in the general case, model space geometry of a curve boundary may consist of curve3d and/or position3d pointers. Consequently, this geometry is obtained by the user as entity3d pointers. The degeneracy of a constituent edge can be detected by the type of the model space geometry.

This class also supports the ownership of its geometry. Being the owner of its geometry would cause it to remove the geometry on destruction of an instance of the class.

Constructor & Destructor Documentation

◆ OdGeCurveBoundary() [1/3]

OdGeCurveBoundary::OdGeCurveBoundary ( )

Parameters

numCurves	[in] Number of curves in the curve boundary.
crv3d	[in] Array of 3D curves of each element in the curve boundary.
crv2d	[in] Array of 2D curves of each element in the curve boundary.
orientation3d	[in] Orientation for each 3D curve element.
orientation2d	[in] Orientation for each 2D curve element.
makeCopy	[in] If true, makes a copy of 3D and 2D curves.
source	[in] Object to be cloned.

◆ OdGeCurveBoundary() [2/3]

		const OdGeEntity3d const	crv3d,
		const OdGeCurve2d const	crv2d,
		bool *	orientation3d,
		bool *	orientation2d,
		bool	makeCopy = `true`

◆ getContour()

void OdGeCurveBoundary::getContour	(	int &	numCurves,
		OdGeEntity3d ***	crv3d,
		OdGeCurve2d ***	crv2d,
		bool **	orientation3d,
		bool **	orientation2d
	)		const

Returns the paramaters for the curve boundary.

Parameters

numCurves	[out] Receives the number of curves in the curve boundary.
crv3d	[in/out] Array of 3D curves for each element in the curve boundary.
crv2d	[in/out] Array of 2D curves for each element in the curve boundary.
orientation3d	[in/out] Orientation for each 3D curve element. Valid only if crv3d is not NULL; if NULL, the caller must delete allocated memory that was intended for numCurves.
orientation2d	[in/out] Orientation for each 2D curve element. Valid only if crv2d is not NULL; if NULL, the caller must delete allocated memory that was intended for numCurves.

Remarks: For each array, provide memory for the array or allow getCountour to allocate it, and delete the elements of the array. If an array is NULL, getCountour allocates memory and the caller must also delete the corresponding array.

◆ isDegenerate() [1/2]

bool OdGeCurveBoundary::isDegenerate ( ) const

Returns true if and only if the curve boundary degenerates to a single 3D point.

Remarks: Currently not implemented.

◆ isDegenerate() [2/2]

bool OdGeCurveBoundary::isDegenerate	(	OdGePosition3d &	degenPoint,
		OdGeCurve2d **	paramCurve
	)		const

Returns true if and only if the curve boundary degenerates to a single 3D point.

Parameters

degenPoint	[out] Receives the point to which the boundary degenerates.
paramCurve	[out] Receives the paramater curve corresponding to degenPoint.

Remarks: If this method returns true, paramCurve is created with the new operator, and it is the responsibility of the caller to delete it.; Currently not implemented.

◆ isOwnerOfCurves()

bool OdGeCurveBoundary::isOwnerOfCurves ( ) const

Returns true if and only if the curve boundary is the owner of the curve boundary parameters.

◆ numElements()

int OdGeCurveBoundary::numElements ( ) const

Returns the number of elements in the curve boundary.

◆ operator=()

OdGeCurveBoundary& OdGeCurveBoundary::operator= ( const OdGeCurveBoundary & crvBoundary )

◆ set()

OdGeCurveBoundary& OdGeCurveBoundary::set	(	int	numCurves,
		const OdGeEntity3d const	crv3d,
		const OdGeCurve2d const	crv2d,
		bool *	orientation3d,
		bool *	orientation2d,
		bool	makeCopy = `true`
	)

Sets the parameters for the curve boundary and returns a reference to it.

Parameters

numCurves	[in] Number of curves in the curve boundary.
crv3d	[in] Array of 3D curves of each element in the curve boundary.
crv2d	[in] Array of 2D curves of each element in the curve boundary.
orientation3d	[in] Orientation for each 3D curve element.
orientation2d	[in] Orientation for each 2D curve element.
makecopy	[in] If true, makes a copy of each 3D and 2D curve.

◆ setToOwnCurves()

OdGeCurveBoundary& OdGeCurveBoundary::setToOwnCurves ( )

Makes the curve boundary own the curve data and returns a reference to the boundary.

Remarks: If the external boundary owns the data, it will be destroyed when the boundary is destroyed.
