csg_ellipsoid: CSG Ellipsoid

Description

CSG Ellipsoid

Usage

csg_ellipsoid(x = 0, y = 0, z = 0, axes = c(0.5, 1, 0.5))

Value

List describing the ellipsoid in the scene.

Arguments

x

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

y

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

z

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

axes

Default `c(0.5,1,0.5)`. Ellipsoid principle axes.
