This function “turns” the curve (as on a lathe) to form a
solid of rotation along the x axis.
turn3d(x, y = NULL, n = 12, smooth = FALSE, ...)
- x, y
Points on the curve, in a form suitable for
y values must be non-negative.
How many steps in the rotation?
logical; whether to add normals for a smooth appearance.
