Anisotropic BSDF(異方性BSDF)

Hair (ヘアー) BSDF

The Anisotropic BSDF is used to add a glossy reflection, with separate control over U and V direction roughness. The tangents used for shading are derived from the active UV map. If no UV map is available, they are automatically generated using a sphere mapping based on the mesh bounding box.

入力

Color(カラー): Color of the surface, or physically speaking, the probability that light is reflected for each wavelength.
Roughness: 反射のシャープさ。0.0で完全に鋭角になり、高い値で滑らかになります。
Anisotropy (異方性): Amount of anisotropy in the reflection; 0.0 gives a round highlight. Higher values give elongated highlights orthogonal to the tangent direction; negative values give highlights shaped along the tangent direction.
Rotation(回転): 異方性接線方向の回転。値0.0は0°回転、0.25は90°、1.0は360°= 0°に相当します。接線方向のテクスチャリングに使用できます。
Normal(ノーマル): Normal used for shading; if nothing is connected the default shading normal is used.
Tangent(タンジェント): 陰影に使用される接線。何も接続されていない場合、デフォルトのシェーディング接線が使用されます。

Properties(プロパティ)

Distribution(分布): Microfacet distribution to use. Sharp results in perfectly sharp reflections like a mirror, while Beckmann, GGX and Ashikhmin-Shirley can use the Roughness input for blurry reflections.
