CSG Ellipsoid

Description

CSG Ellipsoid

Usage

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

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.

Value

List describing the ellipsoid in the scene.

Examples

if(run_documentation()) {
#Generate a basic ellipsoid:
generate_ground(material=diffuse(checkercolor="grey20")) %>% 
  add_object(csg_object(csg_ellipsoid(),material=glossy(color="red"))) %>% 
  render_scene(clamp_value=10, samples=16,fov=20)
  }
if(run_documentation()) {
#Three different ellipsoids:
generate_ground(material=diffuse(checkercolor="grey20")) %>%
