成员函数文档编制

◆  Alloc()

static SplineObject * Alloc ( Int32   pcnt ,
SPLINETYPE   type  
)
static

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

参数
[in] pcnt The point count.
[in] type The spline type: SPLINETYPE
返回
The allocated Spline object, or nullptr if the allocation failed.

◆  Free()

static void Free ( SplineObject *&  bl )
static

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

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

◆  GetSplinePoint()

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

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

参数
[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.
返回
The spline point.

◆  GetSplineTangent()

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

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

参数
[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.
返回
The spline tangent.

◆  GetSegmentR()

const Segment * GetSegmentR ( void  )

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

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

◆  GetSegmentW()

Segment * GetSegmentW ( void  )

Gets the first element in the writable segments array.

返回
The writable segment array address. The Spline object owns the pointed array.

◆  GetSegmentCount()

Int32 GetSegmentCount ( void  )

Gets the number of segments.

返回
The segment count.

◆  GetTangentR()

const Tangent * GetTangentR ( void  )

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

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

◆  GetTangentW()

Tangent * GetTangentW ( void  )

Gets the first element in the writable tangents array.

返回
The writable tangent array address. The Spline object owns the pointed array.

◆  GetTangentCount()

Int32 GetTangentCount ( void  )

Gets the number of tangents.

返回
The tangent count.

◆  GetInterpolationType()

SPLINETYPE GetInterpolationType ( void  ) const

Gets the interpolation type of the spline.

返回
The interpolation type: SPLINETYPE

◆  GetLineObject()

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

Gets a line based object from the spline.

参数
[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.
返回
A line based representation of the spline. The caller owns the pointed Line object.

◆  IsClosed()

Bool IsClosed ( void  )

Checks if the spline is closed.

返回
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.

参数
[in] pcnt The new point count.
[in] scnt The new segment count.
返回
true if the number of points and segments was changed successfully, otherwise false .

◆  SetDefaultCoeff()

Bool SetDefaultCoeff ( void  )

Initializes the spline with default coefficients.

返回
true if successful, otherwise false .
