turn3d: Create a solid of rotation from a two-dimensional curve.

In trestletech/rgl: 3D visualization device system (OpenGL)

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.
