Metallic Material

Metallic Material

Usage
metal(color = "#ffffff", fuzz = 0, importance_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`.

importance_sample

Default `FALSE`. If `TRUE`, the object will be sampled explicitly during the rendering process. If the object is particularly important in contributing to the light paths in the image (e.g. light sources, refracting glass ball with caustics, metal objects concentrating light), this will help with the convergence of the image.

Value

Single row of a tibble describing the metallic material.
