metal: Metallic Material

Description

Metallic Material

Usage

metal(color = "#ffffff", fuzz = 0, implicit_sample = FALSE)

Arguments

color

Default `white`. The color of the sphere. Can be either a hexadecimal code, R color string, or a numeric rgb vector listing three intensities between `0` and `1`.

fuzz

Default `0`. The roughness of the metallic surface. Maximum `1`.

implicit_sample

Default `FALSE`. If `TRUE`, the object will be sampled as part of the scattering probability density function.

Value

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

Examples

# NOT RUN {
#Generate the cornell box with a single metal sphere in the center
scene = generate_cornell() %>%
  add_object(sphere(x=555/2,y=555/2,z=555/2,radius=555/8,material=metal()))
# }
# NOT RUN {
render_scene(scene, lookfrom=c(278,278,-800),lookat = c(278,278,0), samples=500,
             aperture=0, fov=40, ambient_light=FALSE, parallel=TRUE)
# }
# NOT RUN {
#Add a rotated shiny metal cube     
scene = scene %>%
