Question

Anisotropy reflects and transmits light with a directional bias and causes materials to appear rougher or glossier. Anisotropy default value is 0 (zero).
(a) What is the meaning if the Anisotropy value is 0 (zero)?
(b) For which type of material, Anisotropy is preferable? Metal or Wooden (Choose any one).

Hint:

Use anisotropy to create realistic reflections on materials like brushed metals.

Answer 1

(a) Zero Anisotropy: A value of 0 indicates that the material reflects light uniformly in all directions, resulting in a smooth, consistent appearance.

(b) Ideal Material Type: Anisotropy is most beneficial for Metal materials, where it generates a directional sheen characteristic of metallic finishes.
