Detailed Description

Function Documentation

TiglReturnCode tiglProfileGetBSplineCount	(	TiglCPACSConfigurationHandle	cpacsHandle,
		const char *	profileUID,
		int *	curveCount
	)

Returns the number of curves the given profile is made of.

The given profile may be a fuselage profile or a wing profile. Typically, wing profiles consist of two curves (lower and upper curve), fuselage profiles consist of only one curve.

Parameters

[in]	cpacsHandle	Handle for the CPACS configuration
[in]	profileUID	UID of the profile
[out]	curveCount	Number of curves

Returns

• TIGL_SUCCESS if no error occurred
• TIGL_NOT_FOUND if no configuration was found for the given handle
• TIGL_UID_ERROR if profileUID is wrong
• TIGL_NULL_POINTER if profileUID or curveCount NULL
• TIGL_ERROR if some other error occurred

TiglReturnCode tiglProfileGetBSplineData	(	TiglCPACSConfigurationHandle	cpacsHandle,
		const char *	profileUID,
		int	curveid,
		int	nControlPoints,
		double *	cpx,
		double *	cpy,
		double *	cpz,
		int	nKnots,
		double *	knots
	)

Returns the B-Spline data of the given profile curve. This includes the knot vector and the control points of the B-Spline.

The output arrays cpx, cpy, cpz, and knots have to be allocated by the user first. The control point vector arrays must have the size nControlPoints. This value must be queried with tiglProfileGetBSplineDataSizes first. The knot vector array must have the size kKnots. This value has to be queried also using the function tiglProfileGetBSplineDataSizes.

The given profile may be a fuselage profile or a wing profile. Typically, wing profiles consist of two curves (lower and upper curve), fuselage profiles consist of only one curve.

Parameters

[in]	cpacsHandle	Handle for the CPACS configuration
[in]	profileUID	UID of the profile
[in]	curveid	Index of the curve. Number of curves must be queried with tiglProfileGetBSplineCount. 1 <= index <= count
[in]	nControlPoints	Size of the control point vector. To be queried with tiglProfileGetBSplineDataSizes first.
[out]	cpx	X-values of the control point vector.
[out]	cpy	Y-values of the control point vector.
[out]	cpz	Z-values of the control point vector.
[in]	nKnots	Size of the knot vector. To be queried with tiglProfileGetBSplineDataSizes first.
[out]	knots	Knot vector values.

Returns

• TIGL_SUCCESS if no error occurred
• TIGL_NOT_FOUND if no configuration was found for the given handle
• TIGL_UID_ERROR if profileUID is wrong
• TIGL_INDEX_ERROR if curveid knot in range [1, curveCount]
• TIGL_NULL_POINTER if the argument profileUID, cpx, cpy, cpz, or knots are NULL
• TIGL_ERROR if the values nControlPoints, or nKnots are wrong

TiglReturnCode tiglProfileGetBSplineDataSizes	(	TiglCPACSConfigurationHandle	cpacsHandle,
		const char *	profileUID,
		int	curveid,
		int *	degree,
		int *	nControlPoints,
		int *	nKnots
	)

Returns the B-Spline data sizes for a given curve on a profile. This includes size of the knot vector, size of the control point vector and degree of the spline.

The given profile may be a fuselage profile or a wing profile. Typically, wing profiles consist of two curves (lower and upper curve), fuselage profiles consist of only one curve.

Parameters

[in]	cpacsHandle	Handle for the CPACS configuration
[in]	profileUID	UID of the profile
[in]	curveid	Index of the curve. Number of curves must be queried with tiglProfileGetBSplineCount. 1 <= index <= count
[out]	degree	Degree of the B-Spline
[out]	nControlPoints	Size of the control point vector
[out]	nKnots	Size of the knot vector

Returns

• TIGL_SUCCESS if no error occurred
• TIGL_NOT_FOUND if no configuration was found for the given handle
• TIGL_UID_ERROR if profileUID is wrong
• TIGL_INDEX_ERROR if curveid knot in range [1, curveCount]
• TIGL_NULL_POINTER if the argument profileUID, degree, ncontrolPoints, or nKnots are NULL
• TIGL_ERROR if some other error occurred
