[OpenGL] Phong Reflection Model에서의 Material Type Setting Table

Phong Reflection Model에서는 재질의 속성을 ambient, diffuse, specular, shininess 네가지로 정의한다.

이중에 ambient, diffuse, specular는 보통 3차원 벡터이며, shininess는 실수값이다.

 

이 모델을 사용할 경우 단일 컬러 벡터를 사용할 때보다 파라미터가 많기 때문에 원하는 재질를 얻기 위해선 많은 시행착오를 해야 하지만, 능력자들이 편리하게 쓸수 있게 셋팅값을 정리해 놓았다.

OpenGL에서 사용하려면 shininess 값에 128을 곱해야 한다.
