I want to create a 3-D spline, so that it's like a smooth surface in geogebra. I tried using the spline command, which takes a list of point and even though there are different Z values, that is still generating a 2-D spline. What am I missing here ?
I create another tuple inside so now I can use both in case two tuples are required however would be mainly interested in creating a spline so that the enclosed area is completely opaque
