c4d.SplineData – a SplineData class

A datatype which contains information about spline curves. This type is called by value:

#op is a BaseList2D instance and contains a SplineData element at the given position [SPLINESETTINGS_ID]
#in this case you have to send the object back to apply the change.
sdata = op[SPLINESETTINGS_ID]
sdata.mirror()
op[SPLINESETTINGS_ID] = sdata

Methods

SplineData.__init__([v])

Parameter:v (SplineData) – Copy constructor. Return type:SplineData Returns:The new object or None, if allocation failed.

SplineData.SelectAll()

Selects all points.

SplineData.Flip()

Flips the spline.

SplineData.Mirror()

Mirrors the spline.

SplineData.SetRound(r)

Set the tension.

Parameter:r (float) – The tension

SplineData.GetRound()

Gets the tension.

Return type:float Returns:Tension.

SplineData.Maximum()

Makes all Y coordinates less than or equal to 1.

SplineData.Minimum()

Makes all Y coordinates greater than or equal to 0.

SplineData.DeleteAllKnots()

Deletes all knots.

SplineData.DeleteKnot(a)

Deletes a knot.

Parameter:a (int) – The knot index to delete. Return type:bool Returns:True if successful, otherwise False.

SplineData.InsertKnot(x, y, flags=0)

Inserts a knot.

Parameters:

• x (int) – X coordinate
• y (int) – Y coordinate
• flags (int) –

  SPLINE_KNOT_FLAG_NO_HORIZ_MOVE	Don’t allow the knot to move horizontally.
  SPLINE_KNOT_FLAG_NO_VERT_MOVE	Don’t allow the knot to move vertically.

Return type:

int

Returns:

Knot index.

SplineData.GetKnots()

Returns all knots in a list.

Return type:list of Vector Returns:All positions in a list.

SplineData.GetPoint(r)

Gets a point from its X coordinate.

Parameter:r (float) – The x position Return type:Vector Returns:The position

SplineData.GetSelectedCount()

Returns the count of knots which are selected.

Return type:int Returns:The count

SplineData.GetKnotCount()

Gets the knot count.

Return type:int Returns:Knot count.

SplineData.GetRange()

Gets the range of the spline.

Return type:

dict

Returns:

The dict members.

xmin	float
xmax	float
xsteps	float
ymin	float
ymax	float
ysteps	float

SplineData.SortKnots()

Sort the knots.

Return type:int Returns:The new index of the active knot.

SplineData.SetRange(xmin, xmax, xsteps, ymin, ymax, ysteps)

Set the range of the spline.

Parameters:

• xmin (float) – The X min range.
• ymax – The X max range.
• xsteps (float) – The X steps.
• ymin (float) – The Y min range.
• ymax (float) – The Y max range.
• ysteps (float) – The Y steps.
