c4d.utils.SplineLengthData

class c4d.utils.SplineLengthData

Overview

SplineLengthData.__init__

SplineLengthData.Init	Initialize the spline length data object with a spline.
SplineLengthData.Free	Called to free the spline.
SplineLengthData.UniformToNatural	Get the natural position along the spline.
SplineLengthData.GetLength	Returns the length of the spline data object.
SplineLengthData.GetSegmentLength	Get the length of the segment.

Members

SplineLengthData.__init__(self)

SplineLengthData.Init(self, op, segment)

Initialize the spline length data object with a spline.

Parameters

• op (c4d.SplineObject) – The spline object to use.

• segment (int) – The segment of the spline.

Raises

IndexError – If the segment index is out of range : 0<=segment<SplineObject.GetSegmentCount().

SplineLengthData.Free(self)

Called to free the spline.

SplineLengthData.UniformToNatural(self, t)

Get the natural position along the spline.

The uniform position is with respect to the actual length of the spline, whereas the natural position only cares about the interpolation of the curve parameter.

Parameters

t (float) – The uniform position along the spline.

Return type

float

Returns

The natural position in the segment.

SplineLengthData.GetLength(self)

Returns the length of the spline data object.

Return type

float

Returns

The length.

SplineLengthData.GetSegmentLength(self, a, b)

Get the length of the segment.

Parameters

• a (int) – Start of the segment.

• b (int) – End of the segment.
