turn3d

Create a solid of rotation from a two-dimensional curve

Description

This function “turns” the curve (as on a lathe) to form a solid of rotation along the x axis.

Usage

turn3d(x, y = NULL, n = 12, smooth = FALSE, ...)

Arguments

`x, y`	Points on the curve, in a form suitable for `xy.coords`. The `y` values must be non-negative.
`n`	How many steps in the rotation?
`smooth`	logical; whether to add normals for a smooth appearance.
`...`	Additional parameters to pass to `tmesh3d`.

Value

A mesh object containing triangles and/or quadrilaterals.
