how to create a closed spline curve?

in General Discussion • Other • 7 months ago

hello everyone,

I am trying to create a closed shape with spline curve, however my spline curve is always a open one(see below), does anyone know how can I create a closed one? the starting point and the end point should be the same one.

thank you

If you want help you should provide enough code, so we can too run it to try to find out what's wrong!

Anyways, here's a post link which deals w/ the same problem as yours:

Have moved this to Programming Questions since that is what it is?

I agree with GoToLoop - provide some code since the solution will be dependant on how you create and store the spline details.

" since that is what it is?"
Will be once the code is posted. Until then, it is just a general question, that can involve anything (libraries, hardware, vague ideas, whatever).

Make the last three points the same as the first three. This draws a pillowy 5-pointed star:

beginShape();
curveVertex(14,88);
curveVertex(49,6);
curveVertex(80,88);
curveVertex(7,33);
curveVertex(89,32);
// now repeat first three curveVertexes...
curveVertex(14,88);
curveVertex(49,6);
curveVertex(80,88);
endShape();
