<![CDATA[Updating a spline]]>Hi

How to update a spline if the number of points changes ?

If the number of points is the same, we can use the following function:

def spline_update(spline,tabPoint):
	dim = len(tabPoint)
	for i in range(0,dim):
		spline.SetPoint(i,tabPoint[i])

	spline.Message(c4d.MSG_UPDATE)
	return spline

If the number of points changes, we must use the ResizeObject() method

I'm looking for an example, which will save me from doing tests.

I made this function which works fine:

def spline_update(doc,spline,tabNewPoint):
	tabPoint = spline.GetAllPoints()
	
	dim = len(tabNewPoint)
	if len(tabPoint) != dim:
		spline.ResizeObject(dim)
	
	for i in range(0,dim):
		point = tabNewPoint[i]
		spline.SetPoint(i,point)

	spline.Message(c4d.MSG_UPDATE)
	return spline

I have moved your topic due to being in the wrong forum. You might want to look at our geometry_splineobject_s26.py example, as it demonstrates all fundamental aspects of the type, including resizing it.

Cheers,
Ferdinand
