Member Function Documentation

◆ Alloc()

static SplineObject* Alloc	(	Int32	pcnt,
		SPLINETYPE	type
	)

static

Allocates a Spline object. Destroy the allocated Spline object with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters

[in]	pcnt	The point count.
[in]	type	The spline type: SPLINETYPE

Returns: The allocated Spline object, or nullptr if the allocation failed.

◆ Free()

static void Free ( SplineObject *& bl )

static

Destructs Spline objects allocated with Alloc(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters

[in,out] bl The Spline object to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆ GetSplinePoint()

Vector GetSplinePoint	(	Float	t,
		Int32	segment = `0`,
		const Vector *	padr = `nullptr`
	)		const

Gets the spline point at a position along the given segment.

Parameters

[in]	t	The position 0.0 <= t <= 1.0 along the segment. The positioning is natural, for example t = 0.5 is not necessarily at half the length. Use SplineLengthData::UniformToNatural() to get a uniform distribution.
[in]	segment	The segment to get the point in.
[in]	padr	For speedup purposes pass a pointer to the start of the specified segment in the point array. Otherwise the spline has to search its array manually.

Returns: The spline point.

◆ GetSplineTangent()

Vector GetSplineTangent	(	Float	t,
		Int32	segment = `0`,
		const Vector *	padr = `nullptr`
	)		const

Gets the tangent of a spline at a position along the given segment.

Parameters

[in]	t	The position 0.0 <= t <= 1.0 along the segment. The positioning is natural, for example t = 0.5 is not necessarily at half the length. Use SplineLengthData::UniformToNatural() to get a uniform distribution.
[in]	segment	The segment to get the point in.
[in]	padr	For speedup purposes pass a pointer to the start of the specified segment in the point array. Otherwise the spline has to search its array manually.

Returns: The spline tangent.

◆ GetSegmentR()

const Segment* GetSegmentR ( ) const

Gets the first element in the read-only segments array.

Returns: The read-only segment array address. The Spline object owns the pointed array.

◆ GetSegmentW()

Segment* GetSegmentW ( )

Gets the first element in the writable segments array.

Returns: The writable segment array address. The Spline object owns the pointed array.

◆ GetSegmentCount()

Int32 GetSegmentCount ( ) const

Gets the number of segments.

Returns: The segment count.

◆ GetTangentR()

const Tangent* GetTangentR ( ) const

Gets the first element in the read-only tangents array.

Returns: The read-only tangent array address. The Spline object owns the pointed array.

◆ GetTangentW()

Tangent* GetTangentW ( )

Gets the first element in the writable tangents array.

Returns: The writable tangent array address. The Spline object owns the pointed array.

◆ GetTangentCount()

Int32 GetTangentCount ( )

Gets the number of tangents.

Returns: The tangent count.

◆ GetInterpolationType()

SPLINETYPE GetInterpolationType ( ) const

Gets the interpolation type of the spline.

Returns: The interpolation type: SPLINETYPE

◆ GetLineObject()

LineObject* GetLineObject	(	const BaseDocument *	doc,
		Float	lod,
		BaseThread *	thread = `nullptr`
	)		const

Gets a line based object from the spline.

Parameters

[in]	doc	The document containing the spline object. The caller owns the pointed document.
[in]	lod	The level of detail to create the line.
[in]	thread	A thread to check for a break or nullptr. The caller owns the pointed thread.

Returns: A line based representation of the spline. The caller owns the pointed Line object.

◆ IsClosed()

Bool IsClosed ( ) const

Checks if the spline is closed.

Returns: true if the spline is closed., otherwise false.

◆ ResizeObject()

Bool ResizeObject	(	Int32	pcnt,
		Int32	scnt
	)

Changes the number of segments and points for the spline.

Parameters

[in]	pcnt	The new point count.
[in]	scnt	The new segment count.

Returns: true if the number of points and segments was changed successfully, otherwise false.

◆ SetDefaultCoeff()

Bool SetDefaultCoeff ( )

Initializes the spline with default coefficients.

Returns: true if successful, otherwise false.
