Description

CSG Torus

Usage

csg_torus(x = 0, y = 0, z = 0, radius = 1, minor_radius = 0.5)

Value

List describing the torus in the scene.

Arguments

x

Default `0`. x-coordinate on the torus.

y

Default `0`. y-coordinate on the torus.

z

Default `0`. z-coordinate on the torus.

radius

Default `1`. Torus radius.

minor_radius

Default `0.5`. Cross section radius of the torus.
