Sphere Object

Description

Sphere Object

Usage

sphere(
  x = 0,
  y = 0,
  z = 0,
  radius = 1,
  material = diffuse(),
  angle = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  flipped = FALSE,
  scale = c(1, 1, 1)
)

Arguments

x	Default '0'. x-coordinate of the center of the sphere.
y	Default '0'. y-coordinate of the center of the sphere.
z	Default '0'. z-coordinate of the center of the sphere.
radius	Default '1'. Radius of the sphere.
material	Default diffuse. The material, called from one of the material functions diffuse, metal, or dielectric.
angle	Default 'c(0, 0, 0)'. Angle of rotation around the x, y, and z axes, applied in the order specified in 'order_rotation'.
order_rotation	Default 'c(1, 2, 3)'. The order to apply the rotations, referring to "x", "y", and "z".
flipped	Default 'FALSE'. Whether to flip the normals.
scale	Default 'c(1, 1, 1)'. Scale transformation in the x, y, and z directions. If this is a single value, number, the object will be scaled uniformly. Note: emissive objects may not currently function correctly when scaled.

Value

Single row of a tibble describing the sphere in the scene.

Examples

#Generate a sphere in the cornell box.
if(rayrender:::run_documentation()) {
generate_cornell() %>%
  add_object(sphere(x = 555/2, y = 555/2, z = 555/2, radius = 100)) %>%
  render_scene(lookfrom = c(278, 278, -800) ,lookat = c(278, 278, 0), fov = 40, 
               ambient_light = FALSE, samples = 128, clamp_value = 5)
}

#Generate a gold sphere in the cornell box
if(rayrender:::run_documentation()) {
generate_cornell() %>%
  add_object(sphere(x = 555/2, y = 100, z = 555/2, radius = 100, 
                    material = microfacet(color = "gold"))) %>%
  render_scene(lookfrom = c(278, 278, -800) ,lookat = c(278, 278, 0), fov = 40, 
               ambient_light = FALSE, samples = 128, clamp_value = 5)
}
